Dear Sirs:

New Jersey v. New York et al No. 5 Original, October Term 1950

For the record and in compliance with the provisions of the Amended Decree of the United States Supreme Court entered June 7, 1954, I am transmitting herewith the thirtieth Annual Report of the River Master of the Delaware River for the year December 1, 1983, to November 30, 1984.

As the report year began, the total quantity of water in storage in Pepacton, Cannonsville and Neversink Reservoirs of the City of New York in the Delaware River basin totaled 98 billion gallons. This quantity was 12 billion gallons below the drought-warning curve for the reservoirs and 5 billion gallons higher than the situation that existed one year earlier when total contents were 93 billion gallons. Restrictions on diversions and release requirements had been instituted November 9, 1983, in order to con serve water. By letter on October 7, 1983, I had notified the River Master's Advisory Committee that with storage at 121.8 billion gallons and decreasing at a rate of about 1.3 billion gallons per day (bgd), without above-average precipitation and increased runoff, total contents would reach the drought-warning level in early November. I stated that if this situation developed, the Montague flow objective would be reduced to 1 ,655 cubic feet per second (cfs), and that New York City diversions would be limited to 680 million gallons per day (mgd). New Jersey diversions would be limited to 85 mgd. These measures to conserve the water supply were continued until December 19, 1983.

Reservoir contents increased seasonally in early December but re mained below the drought-warning level until December 14, 1983. Storage increased significantly December 14 in response to heavy precipitation December 13-14 so the restrictions on diversions and the reductions in the Montague flow objective were terminated December 20. The augnented conser vation release rates for instream-environmental improvement were resumed January 3, 1984.

Storage continued to increase during the winter months, and by June 1 the combined contents were 279 billion gallons, and all reservoirs were spilling. Streamflow at the gaging station on Delaware River at Montague, New Jersey, was above the 1 ,750 cfs flow specified by the Anended Decree except January 31 and February 1, when the flow dropped to 1700 cfs because of ice conditions in the channel.

The excess-release rate of 1,860 cfs for this year became effective June 15. During July to November, with the daily diversions at customary rates and large releases to maintain the flow objective at Montague, reser voir storage declined rapidly. It was necessary to order directed releases June 23 to July 2 and on an almost daily basis starting, July 29. This continued with very few interruptions until the end of the report year. The excess-release quantity was exhausted on November 13 and the Montague flow was again targeted at 1,750 cfs.

By early November, it again became evident that unless favorable pre cipitation developed, storage in the reservoirs would decline into the drought-warning zone before the end of the month. By letter dated Novem ber 14, 1984, I notified the Advisory Committee members and other interested parties that, if this condition occurred, diversions and releases would again be reduced to conserve water.

Storage in the reservoirs declined below the drought-warning level on November 27. However, precipitation averaging almost 2 inches occurred November 29-30 and storage increased above the drought-warn ing level, averting the need to impose restrictions on diversions and releases.

During regular operations, diversions for water supply for New York City and releases designed to maintain the flow of the Delaware River at Montague were made as directed by this office and as provided in the Decree. Diversions by New York City from the Delaware River basin reser voirs did not exceed the limit specified by the Decree and did not exceed the limits imposed during the period of water-supply deficiency. Diversions by the State of New Jersey did not exceed the limits prescribed in Section V of the Decree and did not exceed the other limitations effected during the year. No water was diverted from the Delaware River River basin by New Jersey after March 16, 1984 because of dredging of the Delaware & Raritan Canal. The dredging project was still ongoing at the end of the report year.

Current-meter measurements of the Neversink Tunnel diversions were made by personnel of this office during October in conjunction with color- velocity measurements by the engineering staff of the New York City Bureau of Water Supply to verify the accuracy of the venturi flow-meter instru ments. The results agreed quite closely except at the highest flows. Further investigation is planned to identify the reasons for the difference. In addition, on November 7, personnel from this office participated in a walk-through inspection of the Neversink Tunnel to deter mine if any structural deterioration had occurred. The inspection was conducted by personnel from New York City Bureau of Water Supply and Central Hudson Gas & Electric Corporation. No significant deterioration was found, but the inside of the tunnel is coated with about 1/4 inch of a material determined to be primarily silt with some imbedded organic matter.

During the report year, the River Master and staff participated in meetings of the Delaware River Basin Commission to assess water supply conditions and to consider measures to ease the growing deficiences. Upon invitation of the representatives of parties to the Decree, the River Master, or his assistants, met frequently with those representatives as a member of the Flow Management Technical Advisory Committee. Discussions primarily centered on proposals for specific releases from reservoirs in the basin and other emergency measures to cope with streamflow deficiencies in the lower basin (downstream from Montague) when the conditions in the upper basin are normal.

The U.S. Geological Survey continued the operation of its field office of the Deputy Delaware River Master at Milford, Pennsylvania. Robert E. Fish, Deputy Delaware River Master, retired from Federal Service on Decem ber 30, 1983 and was replaced by William E. Harkness. Robert W. Baebenroth and Beverly A. Roberts continued to assist with the operation of the office throughout the year.

During the report year, the Milford Office continued the weekly dis tribution of sunmary river data. These weekly reports contained preli minary data on releases from the New York City reservoirs to the Delaware River, diversions to the New York City water-supply system, reservoir con tents, daily segregation of flow of the Delaware River at the Montague gaging station, and diversions by New Jersey. The reports were made available to the State and City representatives on the Delaware River Master Advisory Committee and to other parties interested in the Delaware River operations. A special monthly summary of past hydrologic conditions, supplemented during the low-flow season by an "outlook" of the river flow for the forthcoming month, was made available to the representatives on the Advisory Committee.

Section II of the report describes in detail Delaware River operations during the report year. As shown on page 19 the City of New York diverted a total of 222.252 billion gallons from the basin during the report year ending November 30, 1984, and released 106.685 billion gallons from Pepac- ton, Cannonsville, and Neversink Reservoirs to the Delaware River during the same period. During the low-flow period from June 23 to November 30 (Montague dates) , the River Master directed releases to the Delaware River from these reservoirs totaling 71.576 billion gallons.

Section III of the report describes water quality of the Delaware River estuary and was prepared by Deloris W. Speight, U.S. Geological Survey, Malvern, Pennsylvania. It contains data showing the extent of salinity invasion and other water-quality characteristics in the Delaware River estuary.

During the report year, the following individuals functioned as mem bers of the River Master Advisory Committee:

Delaware Dr. Robert R. Jordan

New Jersey Dirk C. Hbfman, P.E.

New York Edward A. Karath, P.E.

New York City Joseph T. McGough, Jr.

Pennsylvania R. Timothy Weston

A meeting with the Advisory Committee and members of their staff was held May 17 in Milford, Pennsylvania to review the hydrologic con ditions in the basin, the outlook for the 1984 release season and to discuss the current activities of the River Master's office. It was suggested at this meeting that a plan, including costs, be prepared for modernizing data collection equipment and updating forecast procedures. That plan is in preparation and will be submitted to the Advisory Committee for their consideration.

The appreciation of the River Master and staff is expressed for the continued excellent cooperation of all the representatives of the parties to the Decree. Once again, it is gratifying to report that New York City complied with the terms of the Decree, with the temporary reductions of diversions and releases, and with the directives of the River Master.

A draft of this report was furnished to the Advisory Committee members for comment.

Sincerely yours,

Francis T. Schaefer, P.E. Delaware River Master

REPORT OF DELAWARE RIVER OPERATIONS

by William E. Harkness and Robert W. Baebenroth

Abstract

A Decree of the U.S. Supreme Court in 1954 established the position of Delaware River Master. The Decree authorizes diversions of water from the Delaware River basin and requires compensating releases from certain reservoirs of the City of New York to be made under the supervisor! and direction of the River Master. Reports to the Court, not less frequently than annually, were stipulated.

During the 1984 report year, December 1, 1983, to November 30, 1984, precipitation and runoff varied from above average to below average in the Delaware River basin. For the year as a whole, precipitation and runoff were near average. Operations were under a status of drought warning December 1, 1983; however, the above normal precipitation the first half of the year increased storage in the reservoirs to record levels by June 1 , 1984. Below normal precipitation from August to November coupled with large releases to maintain the Montague flow objective and customary di versions for water supply reduced storage in the reservoirs to the drought- warning level by November 27.

Diversions from the Delaware River basin by New York City and New Jersey conformed to the terms of the Amended Decree throughout the year. Releases were made as directed by the River Master at rates designed to meet the Montague flow objective on 127 days between June 23 and Novem ber 30. Releases were made at conservation rates or at rates designed to relieve thermal stress in the streams downstream from the reservoirs at other times.

INTRODUCTION

The Anended Decree of the United States Supreme Court entered June 7, 1954, authorized diversions of water from the Delaware River basin and pro vided for releases of water from certain reservoirs of the City of New York to the Delaware River to be made under the supervision and direction of the River Master. The Decree also stipulated that reports be made to the Court not less frequently than annually. This report describes the River Master operations December 1, 1983 to November 30, 1984.

Definitions of Terms and Procedures

The following definitions apply to various terms and procedures used in the operations described in this report. A table for converting inch-pound units to International System of Units (SI) is given on page v. The map of the Delaware River basin above Wilmington, Delaware (fig. 1 ), indicates the location of pertinent streams and reservoirs.

Time of day. - Time of day is expressed in 24-hour eastern standard time, which included a 23-hour day April 29 and a 25-hour day October 28.

Rate of flow. - Mean discharge for any stated 24-hour period, in cubic feet per second (cfs) or million gallons per day (mgd).

Rate of flow at Montague. - Daily mean discharge of the Delaware River at Montague, N.J., on a calendar-day basis.

Reservoir-controlled releases. - Controlled releases from reservoirs passed through outlet valves 5T the dams or through turbines in powerplants. This does not include spillway overflow at the reservoirs.

Uncontrolled runoff at Montague. - Runoff from the drainage area above Montague exclusive of the drainage area above the Downsville, Cannonsville, Neversink, Wallenpaupack, and Mongaup dams but including spillway over flow at these dams.

Point of maximum reservoir depletion. - Elevation at the top of the highest outlet, sometimesreferredtoas minimum full-operation level.

Storage or contents. - Usable volume of water in a reservoir. Unless otherwise indicated, volume is computed on the basis of level pool and above the point of maximum depletion.

Capacity. - Total usable volume between the point of maximum depletion and the elevation of the lowest crest of the spillway.

Diversions. - The City of New York diverts water from Pepacton, Cannonsville, and Neversink Reservoirs in the upper Delaware River basin through the East Delaware, West Delaware, and Neversink Tunnels, respec tively, to its water-supply system.

The State of New Jersey diverts water from the Delaware River through the Delaware & Raritan Canal.

12

Excess quantity and seasonal period for its release. - As defined in the Decree, the excess quantity of water equals 83 percent of the amount by which the estimated consumption in New York City during the year is less than the City's estimate of continuous safe yield from all its sources of supply obtainable without pumping, except that the excess quantity should not exceed 70 billion gallons. Each year the "seasonal period" for release of excess quantity begins on June 15. The design rate for that period becomes effective at Montague on that date and continues in effect until the following March 15, or until the cumulative total of excess-release credits becomes equal to the seasonal quantity, whichever occurs first.

Daily excess-release credits. - Daily credits and deficits during the seasonal period are equal to the algebraic difference between the daily mean discharge at Montague and 1,750 cfs; however, the daily credit cannot exceed the 24-hour period releases from Pepacton, Cannonsville and Never- sink Reservoirs routed to Montague and made in accordance with direction, with the following exception. During the seasonal period, credits are also made for part or all of other releases from these reservoirs contri buting to daily mean discharge at Montague between the excess-release rate and 1 ,750 cfs.

Precipitation

Precipitation observed on the basin above Ifontague for the 1984 report year was above normal, totaling 48.89 inches. Precipitation was excessive for December, April, May and July and was deficient for January, September and October. The monthly precipitation during the report year is shown in table 1.

These data were computed from records collected by the National Weather Service, New York City Department of Environmental Protection, Bureau of Water Supply and the River Master, at ten stations distributed over the basin area above Mantague, December through May, nine stations June through October and eight stations in November.

December to May is generally considered the normal time of year when surface- and ground-water reservoirs fill. During this period in 1983-84, precipitation totalling 29.18 inches was observed, which was 143 percent of the 43-year average. During June to November, 19.71 inches of precipi tation was observed, which was 87 percent of the 43-year average. The maximum monthly precipitation listed during the year for any of the ten stations was 10.23 inches in May at Liberty, N.Y.; the minimum monthly precipitation observed was 0.60 inches in September at Milford, Pa.

Acknowledgments

Part of the hydrologic data presented are records of U.S. Geological Survey gaging stations. These records were collected, computed and fur nished by the Offices of the U.S. Geological Survey at Albany, New York, Malvern, Pennsylvania, and Trenton, New Jersey, in cooperation with the States of New York and New Jersey, the Commonwealth of Pennsylvania, and the City of New York.

The River Master daily operation records were prepared by the Milford Office of the Delaware River Master from hydrologic data collected prin cipally on a day-to-day basis. Data for these records were collected and computed by the Milford Office or were furnished by agencies, as follows: Data from Pepacton, Cannonsville and Neversink Reservoirs by the New York City Department of Environmental Protection, Bureau of Water Supply; from Lake Wallenpaupack by the Pennsylvania Power & Light Company; and from Mongaup Reservoir by Orange and Rockland Utilities, Inc.

OPERATIONS

December to May

During the first half of the report year, precipitation was 8.84 inches above average and ranged from deficient to excessive. Precipitation during May, 9.14 inches, was the highest May in the period of record. Pepacton, Cannonsville and Neversink Reservoirs reached their highest combined storage since the completion of Cannonsville Reservoir, 281.634 billion gallons, 104 percent of capacity on May 30.

14

On December 1, 1983, Pepacton Reservoir contained 62.851 billion gallons of water in storage above the point of maximum depletion, or 44.8 percent of the reservoir's storage capacity of 140.190 billion gallons. Cannonsville Reservoir contained 20.790 billion gallons, or 21.7 percent of the reservoir's storage capacity of 95.706 billion gallons and Neversink Reservoir contained 14.643 billion gallons, or 41.9 percent of the reser voir's storage capacity of 34.941 billion gallons. The combined storage in the three reservoirs as of December 1 was 98.284 billion gallons, or 36.3 percent of their combined capacity. Daily storages in Pepacton, Cannonsville and Neversink Reservoirs are shown in tables 10, 11 and 12, respectively.

On November 9, 1983, during the previous report year, the combined storage of Pepacton, Cannonsville and Neversink Reservoirs declined below the drought-warning level of the operation curves recommended by the par ties to the Decree. At that time the permissible diversion rate to the New York City Water-Supply system was reduced from 800 to 680 mgd and the design rate of flow of Delaware River at Mantague, New Jersey was changed from 1,750 to 1,655 cfs. Those rates were continued until December 19, 1983, vhen the combined storage had been more than 15 billion gallons above the drought-warning level for 5 consecutive days. On December 20 the allowable diversion rate of 800 mgd, and the Montague minimum basic design rate of 1,750 cfs, were resumed.

Diversions to Rondout Reservoir December 1, 1983 to May 31, 1984, totaled 89.065 billion gallons and averaged 487 mgd.

From December 1 to May 31 the anticipated discharge at Montague, ex clusive of water released from the City reservoirs, did not fall below the applicable design rate and no releases were directed to meet the Montague flow objective. During this period, New York City made releases for con servation purposes at rates set forth in the Interstate Water Management Recommendations of the Parties to the Decree. Releases were made at the basic conservation rates December 1 to January 2 and at the augmented conservation rates thereafter. The conservation release rates are shown in table 2.

There were two days during the December to May period when the observed discharge at Montague was less than the prevailing design rate. (See table 15.) These deficiencies were caused by ice in the channel during cold weather.

Inflow to the City's reservoirs during the December through May period generally exceeds draft rates and therefore increases storage. The average inflow to Pepacton, Cannonsville, and Neversink Reservoirs for these six months during the 43-year period, December 1940 to May 1983, was 304.8 billion gallons. During the correspondending six months of the current report year, inflow to the three reservoirs totaled 392.8 billion gallons.

Loss chargeable to evaporation was considered to be insignificant and was not included in the computation. Storage in the three reservoirs increased from 97.187 billion gallons on November 30, 1983 to 281.416 billion gallons May 31, 1984.

June to November

Precipitation during the previous six months was almost 9 inches above average, but during the June to November period, precipitation was below average all months except July. From August 1 to November 28, a deficiency of about 4.2 inches below the 43-year average accrued.

16

Diversions to Rondout Reservoir June 1 to November 30 totaled 133.187 billion gallons. The equivalent diversion rate did not exceed the limit specified by the Decree and was 728 mgd on November 30. Releases were required to satisfy the Montague Formula on 127 days when the antici pated discharge at Montague exclusive of water released from the City reservoirs, fell below the design rate. Releases at augmented conservation rates or at rates designed to relieve thermal stress were made at other times from each reservoir by the City of New York.

During June 1-14, the flow required to be maintained in the Delaware River at Montague was the minimum basic rate of 1,750 cfs. The fore casted discharge, exclusive of releases from Pepacton, Cannonsville and Neversink Reservoirs, was greater than 1,750 cfs each day. During that per- the observed discharge at Montague was always greater than 1 ,750 cfs.

On June 15, the seasonal period began for release of the excess quantity of water from the reservoirs, and the design rate at Montague was increased to 1 ,860 cfs. This rate was composed of the basic rate of 1 ,750 cfs plus 110 cfs of required excess releases.

The New York City Department of Environmental Protection, Bureau of Water Supply, furnished the River Master with the following advance data for the 1984 calendar year:

1. The estimated continuous safe yield, from all the City's sour ces, obtainable without pumping, is 1,665 mgd, or a total during the calendar year 1984 of 1,665 x 366 days = 609.390 billion gallons.

2. The estimated consumption that the City must provide from all its sources of supply during the calendar year 1984 is 591.582 + 7.250 = 598.832 billion gallons.

On the basis of the provisions of the Decree and the above data, the aggregate quantity of excess-release water (see definition page 13.) was 83 percent of (609.390 - 598.832) or 8.763 billion gallons. The Montague design rate during the excess release period beginning June 15, 1984, was computed as:

1,750 + 8.763 billion gallons x 1,547 cfs/bgd = 1>86Q cfg

120 days

Data on consumption of water by the City of New York for each calendar year, beginning in 1940, are shown in table 16.

The design rate of 1,860 cfs at Montague was required June 15 to November 13, when the excess-release quantity was expended. Accordingly, directed releases from the City reservoirs were designed to maintain the rate of 1 ,860 cfs at Montague June 15 to November 13 and a rate of 1 ,750 cfs November 14-30.

17

On the basis of advance estimates, releases from the reservoirs de signed to maintain the prevailing rates at Montague were required on 127 days during the period June 23 to November 30 (table 14). During this period, there were 58 days when the observed discharge at Montague was less than the prevailing design rate and 63 days when the observed discharge was above the prevailing design rate (table 15). Deficiencies or excesses in flow on these days were attributed to the uncontrolled flow, weather adjustment, or powerplant releases which were other than those anticipated.

The hydrographs of plate 1 , June 1 to November 30, show the total dis charge at Montague; the portion derived from uncontrolled runoff downstream from the reservoirs; the portion contributed by the power reservoirs; and the portion contributed by Pepacton, Cannonsville and Neversink Reservoirs. In analyzing the water budget at Montague, the uncontrolled runoff downstream from the reservoirs was computed as the residual of observed flow less releases from all reservoirs and therefore was subject to all the errors in observations, transit times, and routing of the several components of flow. Because all of these uncertainties are contained in these figures, the computed hydrograph of uncontrolled runoff was somewhat ragged.

The advance estimate of flow of the Delaware River at tfcotague ex clusive of the releases from the New York City reservoirs was less than the design rate on 15 days scattered throughout the period from June 23 to August 10, 1984. From August 11 to November 30, tiie advance estimate was always less than the design rate and releases were directed every day. The table below compares the advance estimates of the various contribu tions to the flow at Montague to the observed observations during the August 11 to November 30, 1984 period.

From December 1, 1983 to November 30, 1984, diversions to Rondout Reservoir totaled 222.252 billion gallons, and all releases from the New York City reservoirs to the Delaware River totaled 165.042 cfs-days (106.685 billion gallons).

During the year, maximum storage in Pepacton Reservoir was 144.249 billion gallons, or 103 percent of capacity, on May 30. Maximum storage in Cannonsville Reservoir was 102.224 billion gallons, or 107 percent of capacity, on May 31. Maximum storage in Neversink Reservoir was 35.563 billion gallons, or 102 percent of capacity, May 30. The maximum combined storage in the three reservoirs during the year was 281.634 billion gal lons, or 104 percent of capacity, on May 30.

Minimum storage during the year in Pepacton Reservoir was 62.851 bil lion gallons, or 45 percent of capacity on December 1 and 6, 1983. The minimum storage in Cannonsville Reservoir was 20.790 billion gallons, or 22 percent of capacity on December 1. Minimum storage in Neversink Reser voir was 12.076 billion gallons, or 35 percent of capacity on November 29, 1984. Minimum combined storage in the three reservoirs was 98.284 billion gallons, or 36 percent of capacity December 1, 1983.

A resume 1 of the combined storage of the three reservoirs on the first day of the month June 1967 to December 1984 is shown in figure 3. Storage was above the median June 1 , below the median all other months and was within the range between the highest and the lowest storage of earlier years, except for a new high on June 1 .

On November 30, combined storage in the three reservoirs was 110.248 billion gallons, or 41 percent of their combined capacity. During the year, combined storage increased 13.061 billion gallons, or 5 percent of capacity.

SUPPLEMENTARY RELEASE FROM VftTJ.KMP AT TRACK POWERPLANT

An agreement between Pennsylvania Power & Light Company and the City of New York provides for supplementary releases from Wallenpaupack hydroelectric powerplant if the Delaware River Basin Commission requests them to compensate for water consumed at the Company's Martins Creek steam- electric generating station. Releases may be requested if the flow of the Delaware River at Trenton, N.J. is expected to be less than 3,000 cfs for more than three consecutive days. No supplementary releases were requested during the year.

W&TER BUDGET, DELAWARE RIVER AT MDNTAGUE, N.J.

The data and computations of the water budget formed the basic opera tion records required to carry out the River Master's specific responsi bilities with respect to the Montague Formula and the Interstate Water Management Recommendations during the report year. The water budget has two parts: (1) advance estimates of the daily average flow at Montague, exclusive of controlled releases from New York City's reservoirs (table 14) and (2) segregation of the daily average flow at Montague among its various source components (table 15). The time intervals required for water to travel from the various sources to Montague were taken into account.

Discharge of the Delaware River at Montague was composed of the following source components:

1. Controlled releases from Lake Wallenpaupack on Vfellenpaupack Creek in the production of hydroelectric power.

2. Controlled releases from Mongaup Reservoir on Mongaup River in the production of hydroelectric power.

3. Runoff from the uncontrolled area upstream from Montague.

4. Controlled releases from Pepacton, Cannonsville and Neversink Reservoirs of the City of New York.

The release from the City's reservoirs necessary to maintain the applicable rate of flow at Montague was computed from the advance estimates of flow at Montague, exclusive of controlled releases from the City's reservoirs.

TIME OF TRANSIT

The average times for the effective transit of water from the various sources of controlled supply to Montague used for discharge routing during the 1984 report year are as follows:

Source Hours

Pepacton Reservoir 60Cannonsville Reservoir 48Neversink Reservoir 33Lake Wallenpaupack 16Mongaup Reservoir 12

20

This schedule was developed from reservoir and powerplant operations and gaging-station records of prior years and was found generally suitable. At times, noticeable exceptions occur, e.g., when a large release from Cannonsville Reservoir follows a small one, a large part of the release is expended in filling the channel en route, and the remainder may appear at Montague as much as 12 hours late. During the winter, the cold weather causes ice to form in the stream, which, together with the low streamflow, gradually increases the resistance to streamflow and lengthens the time of transit.

SEGREGATION OF FLOW AT MDNTAGUE

The River Master daily operation record of reservoir releases and daily segregation of flow among the various source components contributing to the flow of the Delaware River at Montague is shown in table 15 on page 54. The arrangement of data conforms with the downstream movement of water from the various sources to Montague. A horizontal summation of data in the table is equivalent to routing the various contributions to Montague, using the schedule for travel time of water discussed previously. The uncontrolled runoff was computed by subtracting the contributions of the several other sources from the observed discharge at Montague.

COMPUTATION OF DIRECTED RELEASES

In the daily operations, it was necessary that the River Master utilize: (1) discharges computed from recorded or reported stream gage heights for various 24-hour periods without current information about changes in stage-discharge relations that might have occurred; (2) daily discharge from New York City's three reservoirs obtained from venturi meters; (3) rainfall reports for the previous 24 hours; (4) actual powerplant operations converted to daily discharge; (5) advance estimates of power demand converted to daily discharge; (6) advance estimates of uncon trolled runoff at Montague; and (7) average times for routing of water from the several sources. Variable errors of estimate occur in projecting data, but these data must be used in the daily design and direction of releases from New York City reservoirs.

The time of transit of water from Pepacton Reservoir to Montague was greater than that from any other reservoir above Montague, therefore, the time of daily directed releases to maintain prescribed rates of flow at Montague was based on time of transit from Pepacton Reservoir. Releases from Cannonsville and Neversink Reservoirs were timed to arrive at Montague concurrently with releases from Pepacton Reservoir. To allow for the actual differences in transit times, daily directed releases began at Pepacton at 1200, at Cannonsville at 2400, and at Neversink Reservoir at 1500 the following day.

21

The determination of the amount of release required from the City's reservoirs to maintain specified rates of flow at Montague was based on estimates of releases from Lake Wallenpaupack and Mongaup Reservoir and an estimate of the uncontrolled runoff at Montague. Taking into account the time of transit from these sources to Msntague, this determination required that advance estimates of the following components be made on the morning of each day: (1) the expected release of water from Lake Wallenpaupack for power production for a 24-hour period, beginning at 0800, two days later; (2) expected release of water from Mongaup Reservoir for power production for a 24-hour period two days later, beginning at 1200; and (3) expected uncontrolled runoff at Montague three days later. The River Master daily operation record for computing daily directed release from the City's reservoirs during the periods of low flow is shown in table 14.

The electric power companies cooperated fully in furnishing advance estimates of powerplant release (table 14). As the hydroelectric plants were used chiefly for meeting peak-power demands of the system, advance estimates were subject to many modifying factors such as the influence of the vagaries of weather upon peak-power demand and unpredictable trans mission and mechanical difficulties in electric-system operation. As a result, the actual use of water for power generation was at times at con siderable variance with the advance estimates that were used by the River Master's office in design computation. Furthermore, it was impractical for the companies to estimate their probable operation on any period other than 24 hours. In the estimates for the Wallenpaupack plant, the time factor was of little concern, as power operations during periods of low flow were usually between 0800 and 2400, T«hich fell within the 24-hour period beginning at 0800. In routing the Mongaup Reservoir release esti mates, some error was introduced at times, as the power operations during periods of low flow were usually between 0700 and 2200 which spanned the 1200 to 1200 routing period.

For computation purposes during periods of low flow, the estimate of uncontrolled runoff at Montague three days in advance was treated as two items: (1) Present runoff and (2) estimated increase in runoff from preci pitation. The present runoff was computed for 2,156 square miles of un controlled drainage area above Montague based on conditions over the drainage area as of 0800 on the morning the estimate was made. The esti mated increase in runoff was computed from precipitation \iiich was fore cast to occur on the day the estimate was made and the two following days. Estimated quantities for these items are shown in table 14.

During the winter period, the advance estimate of the uncontrolled runoff (present conditions) was based on nearby gaging stations and on the recession curve of the uncontrolled flow at Mantague projected to the date, three days hence, under design.

22

During open-river conditions, the present runoff portion of the advance estimate of uncontrolled runoff was based on discharges as of 0800 at gaging stations listed below:

Drainage area Station (square miles)

Beaver Kill at Cooks Falls, N.Y. 241Cadosia Creek at Cadosia, N.Y. 17.9Oquaga Creek at Deposit, N.Y. 67.6Equinunk Creek at Equinunk, Pa. 56.3Callicoon Creek at Callicoon, N.Y. 110Tenmile River at Tusten, N.Y. 45.6Lackawaxen River at Hawley, Pa. 290Shohola Creek near Shohola, Pa. 83.6Neversink River at Port Jervis, N.Y. 336

The procedure for computing the advance estimate combined a routing and recession (as applicable) of the 0800 discharges of the Beaver Kill, Oquaga, Equinunk, Callicoon and Shohola Creeks and Tenmile, Lackawaxen, and Neversink Rivers gaging stations to Montague, with a computed yield from the remaining ungaged, uncontrolled drainage area. Releases from Never sink Reservoir were deducted from discharge of the Neversink River site. The yield from the ungaged, uncontrolled drainage area was estimated on the basis of the yield of Cadosia, Oquaga, Equinunk, and Callicoon Creeks, and Tenmile and Lackawaxen Rivers with routing and recession by individual gaging stations.

The advance estimate of increase in runoff from precipitation is shown in table 14 under the heading of "Weather Adjustment." The National Weather Service Office, Philadelphia, Pa., cooperated throughout the low- flow periods by furnishing quantitative forecasts of average precipitation over the drainage area above Montague and air temperatures for each day of the three-day period. During the winter, the probable increase in runoff was estimated from the current state of snow and ice and from forecasted temperature and precipitation for the several days under consideration. During open-river conditions, runoff from the forecasted precipitation was estimated from previously established relationships.

The total anticipated flow at Montague, exclusive of releases from the City's reservoirs (table 14), was the sum of the forecasted releases from the power reservoirs, the estimated uncontrolled runoff under then current conditions, and the weather adjustment. The amount by which this computed flow was less than the prescribed Montague rate indicated the expected deficiency at Montague, which would have to be made up by corresponding releases from New York City reservoirs.

23

There were times when revised forecasts of weather or powerplant re lease in substantial amount became available before the completion of the required release from New York City reservoirs. At such times, the re lease required from New York City reservoirs was recomputed on the basis of the revised information, and the release required was changed to re vised indicated deficiency. Usually this procedure resulted in a reduced release requirement from New York City reservoirs and the conservation of water. Only the final figures are shown in table 14.

When the estimates of anticipated flow at Montague, inclusive of New York City releases, were too high, insufficient water was released. When the estimates were too low, more water was released than necessary. Such deviations from the estimates were unavoidable; however, cumulative deviations in the estimating procedure over a period of time were reduced by using an adjustment based on the amount by which the cumulative directed releases were greater or less than the cumulative releases actually re quired to maintain the prescribed rate of flow at MDntague. The cumula tive difference between directed and actually required releases was divided by minus 10 to spread the balancing adjustment over 10 days, but was limited to a maximum of ±110 cfs. The mechanics of determining the balancing adjustment are shown in colunns 8 to 13 of table 14. As the cumulative difference could be determined only after the actual flow at Mantague was computed, the balancing adjustment was entered in column 7 four lines below its computation in columns 13. The balancing adjustment was applied June 25 to November 13 and was helpful in reducing cumulative errors and in conserving water.

DIVERSIONS TO NEW YORK CITY V&TER SUPPLY

Table 13 shows diversions from Pepacton, Cannonsville and Neversink Reservoirs to the New York City water-supply system during the report year. The tabulation includes a running account of the average rates of the combined diversions from the reservoirs, computed as prescribed by Interstate Water Management Recommendations of the Parties to the Decree December 1-19 and the equivalent rate as prescribed by the Decree Decem ber 20 to November 30. The tabulation shows that the allowable maximum equivalent diversion rates were not exceeded at any time.

Tables 10, 11 and 12 show storage in Pepacton, Cannonsville and Never sink Reservoirs, respectively, above "point of maximum depletion" or mini mum full-operating level.

On December 1, 1983 combined storage in the three reservoirs was 98.284 billion gallons, which was below the drought warning level as defined by the Interstate Water Management Recommendations. This was the lowest com bined storage during the year. Storage increased gradually but remained below the drought warning level until a significant increase occurred December 14 in response to heavy precipitation throughout the basin. Storage increased above the drought-warning level on December 14 and drought-warning status was lifted December 19 when storage had remained above drought-warning level for five consecutive days.

Storage continued to increase seasonally throughout the winter and spring and reached a combined maximum storage of 281.634 billion gallons on May 30. It remained at fairly high levels throughout the summer months. However, the combination of below-normal precipitation from August through November coupled with large releases to meet the Montague formula and customary diversions for New York City water supply, storage declined to the drought-warning level on November 27. Heavy precipitation occurred Novem ber 29 and storage increased above drought-warning level, averting the need to impose conservation measures.

Storage November 30 was 110.248 billion gallons, 0.248 billion gallons above drought-warn ing level.

ANALYSIS OF FORECASTS

Forecasts of the flow at Montague based on the anticipated flow of the several components (exclusive of the release from the City's reservoirs) vary somewhat with those actually experienced on most days even under the most favorable conditions. The daily variations in the several components are often largely compensating with the resulting forecast being fairly accurate. Forecasts were compared with actual uncontrolled runoff and powerplant releases from August 11 to November 30, which included most of the days for which releases were directed.

A comparison of the hydrographs on figure 2 of forecast uncontrolled runoff and the actual uncontrolled runoff indicate that the forecasting procedures were generally adequate. The forecast included anticipated uncontrolled runoff under then-existing conditions plus the weather adjustment based on forecast precipitation. The total uncontrolled runoff during August 11 to November 30 (Montague dates) was 76,402 cfs-days. (See table on page 18.) The forecast of uncontrolled runoff for those days was 68,098 cfs-days, or 10.9 percent less than actual runoff. However, 4,858 cfs-days of runoff (59 percent of the difference) occurred on November 30 due to almost 2 inches of rain that fell over much of the area that was not forecast.

During this same period, the total actual release from the powerplants was 29,822 cfs-days. The advance estimate of powerplant releases for those days was 27,384 cfs-days, or 8.2 percent less than actual releases.

On the basis of the observed discharges at Montague, exact forecasting of releases required from the City's reservoirs during the release period June 21 to November 30, would have totaled 108,790 cfs-days. The releases, as designed, totaled 110,490 cfs-days, or 1.6 percent more than for exact forecasting.

COMPARISONS OF RIVER MASTER OPERATION DATA AND OTHER STREAMFLOW RECORDS

It has been explained that the River Master operations are, in effect, day-to-day operations, for which it is necessary to use preliminary records of streamflow. The following summaries show comparison of records used in the River Master operations and Geological Survey records. In the com parison of releases approximating conservation rates only, data were used in units of million gallons per day and converted to cubic feet per second in the summaries.

Releases from New York City Reservoirs

The River Master operations data on the controlled releases from Pepacton, Cannonsville and Neversink Reservoirs, to the Delaware River were obtained from calibrated instruments connected to venturi meters in stalled in the outlet conduits.

26

The Geological Survey gaging station on the East Branch Delaware River at Downsville, N.Y., is 0.5 mile downstream from Pepacton Reservoir dam. The discharge shown in table 3 includes releases and spillage from Pepacton Reservoir. It also includes a small amount of seepage, which enters the channel between the dam and gage site and, a small amount of runoff, which originates between the dam and gage site. The drainage area at the dam is 372 square miles.

Releases were made at conservation or other rates by New York City during the year. For flows of approximately 6.0, 55, 110 and 600 cfs at the gaging station, the venturi meter instruments indicated 44.0, -8.1, -5.4 and +5.5 percent difference, respectively, in rates of release from the reservoir than those shown by the gaging-station records.

The Geological Survey gaging station on the West Branch Delaware River at Stilesville, N.Y., is 1.4 miles downstream from Carmonsville Dam. The discharge shown in table 4 includes releases and spillage from Carmonsville Reservoir and the runoff from 2 square miles of drainage area between the dam and the gage site. The drainage area at the dam is 454 square miles, and that at the gaging station is 456 square miles.

Releases were made in a range from conservation to high rates during the year. For flows of approximately 13 and 35 cfs at the gaging station, the venturi meter instruments indicated 39 and 4.2 percent less water, respectively, being released from the reservoir than those shown by the gaging-station records. The venturi indicated 9.4 percent more discharge than that shown by the gaging-station records at flows of approximately 340 cfs and 3.6 percent more discharge for flows in the 1,100 cfs range.

The Geological Survey gaging station on the Neversink River at Never- sink, N.Y., is 1,650 feet downstream from Neversink Dam. The discharge shown in table 6 includes releases and spillage from Neversink Reservoir and, during storms, a small amount of runoff, which originates between the dam and gage site. The drainage area at the dam is 92.5 square miles and that at the gaging station is 92.6 square miles.

Releases were made at conservation or other low flows by New York City during the year. For flows of approximately 5, 24, 45 and 65 cfs at the USGS gaging station, the venturi meter instrument indicated +2.5, +4.1, -2.5 and +7.6 percent difference, respectively, in rates of release from the reservoir than those shown by the gaging-station records.

The above comparisons indicate good agreement between the data from the venturi meters and U.S. Geological Survey gaging stations at all stations for all ranges of flow except for the very low flows at Carmonsville Reservoir. The gaging station records shown significantly more water at low flows than the venturi meter records for this site.

27

Releases from Lake Wallenpaupack

In the River Master operations December 1 to November 30, records of daily discharge through the Wallenpaupack powerplant were furnished by the Pennsylvania Power & Light Company. Daily discharges were computed on an 0800 to 0800-time basis to allow for the 16-hour average transit time to Montague.

The records of daily mean discharges for Wallenpaupack Creek at Wilson- ville, Pa., published by the Geological Survey, were also furnished by the Company. These discharges, shown in table 5, represent the flow through the turbines of the powerplant and are computed on a midnight to midnight basis. The gates at the dam were opened to allow spillage from May 29 to June 1, 1984. During this period, 7,757 cfs-days, as computed by the Company, was spilled from Lake Wallenpaupack.

During December 1983 through November 1984, the River Master's record based on computations by Pennsylvania Power & Light Company, indicated 0.2 percent more discharge than the Geological Survey record. This diff erence was due to the difference in the time frame of the computations and a slight difference in the computation of the spillage.

Delaware River at Montague, N.J.

The River Master's operation record indicated 2.2 percent less dis charge for the year than the Geological Survey record, and daily records were generally in good agreement.

Diversion Tunnels

Records of diversions through the East Delaware, West Delaware, and Neversink Tunnels were furnished to the River Master's office by the City of New York. These records were obtained from New York City's calibrateid instruments connected to venturi meters installed in the tunnel conduits. Current-meter measurements were made by the River Master's office to verify the accuracy of the reported diversions. The current-meter measurements were made in the outlet channels downstream from the tunnels.

Water diverted from Pepacton Reservoir discharges through the East Delaware tunnel into Rondout Reservoir. The elevation of Rondout Reservoir was too high many months of the year to permit access to the outlet channel, which is used for measuring discharge from the tunnel by current meter. The results of two current-meter measurements showed on the average that the venturi-meter instruments gave higher figures by 6.3 percent for the totalizer, 7.6 percent for the manometer and 6.4 percent for the indicator needle.

28

The powerplant that used the water diverted through the tunnel operated most days of the year. On days when the powerplant was not in operation, there was a small amount of leakage through the wicket gates, which was not recorded on the totalizer. Results of a current-meter measurement March 4, 1982, indicated a rate of 10.9 cfs from cooling water and leakage.

Based upon measurements obtained this year and in previous years, the record of quantity of water diverted through the East Delaware Tunnel should be substantially correct.

The West Delaware tunnel is used to divert water from Carmonsville Reservoir into Rondout reservoir. Due to the high level of Rondout reser voir for much of the year only two current-meter measurements were made to compare with venturi measurements. These two measurements indicated that the venturi gave higher results by 14 percent for the totalizer, 23 percent for the manometer and 11 percent for the indicator needle. Inspections of the channel downstream from the outlet, when valves were closed showed negligible leakage.

The Neversink Tunnel is used to divert water from Neversink reservoir into Rondout reservoir. Results of the comparative data showed that the venturi measurements and 10 current-meter measurements agreed fairly well. The average difference between the two methods showed the venturi higher by 3.6 percent for the totalizer, 6.6 percent for the manometer, and 6.4 percent for the indicator needle.

A series of measurements of flows through the Neversink Tunnel by-pass works was made October 1-3 to check the accuracy of the venturi-meter instruments. Measurements at flows of approximately 180, 280, 390 and 450 mgd were made by the color-velocity method by personnel of New York City and by current-meter method by hydrologists from the River Master office.

There was good agreement between the results of the color velocity tests, venturi-meter totalizer and the current meter measurements except at the highest flow. At 456 mgd by color-velocity method, the venturi- meter totalizer gave 458 mgd but the current meter method only showed 426 mgd (-6.6 percent). The results of these tests and other current meter checks indicate that the reported record of the quantity of water diverted through the Neversink Tunnel was substantially correct.

29

DIVERSIONS BY NEW JERSEY

According to the terms of the Decree, the State of New Jersey may divert for use outside the Delaware River basin from the Delaware River or its tributaries in New Jersey, without compensating releases, a quantity of water not to exceed 100 mgd (154.7 cfs), as a monthly average, with the diversion on any day not to exceed 120 mgd (185.6 cf s). The diversion through the Delaware & Raritan Canal was recorded at the gaging station at Kingston, N.J. The gaging station is 6.6 miles beyond the Delaware-Raritan divide, and records include a slight amount of inflow from the Raritan River basin. The Interstate Water Management Recommendations of the Parties to the Decree, reduced allowable diversions by New Jersey to an average of 85 mgd (131.5 cfs) December 1-19, 1983 due to the drought warning status in effect since November 9, 1983. Allowable diversions were increased December 20, 1983 to those provided by the Decree.

In order to increase the carrying capacity of the Delaware & Raritan Canal, the New Jersey Water Supply Authority began dredging the canal in March 1984. The canal was closed at about noon on March 16 near Washington Crossing, New Jersey. However, since the gaging station is downstream from the point of closure and no water from the Raritan River Basin was pumped into the canal until later, it was assumed that all flow up to and including March 17 at the Kingston gaging station was from the Delaware River Basin and that all flow thereafter was from the Raritan River Basin.

Summarized below are the records of discharges at the Kingston gaging station from Table 8 that are diversions from the Delaware River basin. The summary table shows that the Decree limitations were not exceeded during the year, December 1 to November 30. The table also shows that the average rates of the Interstate Water Management Recommendations were not exceeded.

OONFORMANCE OF OPERATIONS AS PROVIDED UNDER AMENDED DECREE OF THE U.S. SUPREME OXJRT, DATED JUNE 7, 1954

At the beginning of the report year, conservation measures including reductions in allowable diversions from the basin and rates of flow of the Delaware River at Montague were in effect due to a drought-warning status having been declared November 9, 1983. With general improvement over drought and the filling of the reservoirs, the restrictions were lifted December 20.

Diversions from the Delaware River basin to the water-supply system of the City of New York were less than the 800 mgd authorized by the Decree. Diversions during the drought-warning period also were less than the 680 mgd permissible level in effect for that period. Allowable and actual diver sions are shown in the following table:

Effective dates

Allowable diversions Equivalent rate not to exceed

Under Compensating Releases of the Montague Formula, the City released water from its reservoirs at rates designed by the River Master to maintain the minimum basic rate of flow of 1,750 cfs at Montague December 20 to June 14 and November 14-30; and at the excess-release rate of 1,860 cfs June 15 to November 13. Releases from the reservoirs, aider the reduced rates provided in the Interstate Water Management Recommendations and in accordance with the design data of the River Master, were made to provide 1 ,655 cfs at Montague, N.J. December 1-19.

Diversions from the Delaware River basin by the State of New Jersey were found to be less than the authorized monthly average of 100 mgd and less than the authorized maximum daily flow of 120 mgd uider the Anended Decree. During the drought-warning period, December 1-19, allowable and actual diversions were 85 mgd and 67 mgd respectively.

Section III

QUALITY OF THE DELAWARE RIVER ESTUARY By Deloris W. Speight

INTRODUCTION

This section describes the water-quality monitoring program carried out by the U.S. Geological Survey in the Delaware Estuary during the 1984 report year. Also presented here are some of the data that were obtained by this program and a brief discussion of the significance of the data.

WATER-QUALITY M3NITORING PROGRAM

Water quality of the Delaware River and Estuary was monitored at sites between Trenton, N.J., and Ship John Shoal Lighthouse, N.J. Data were acquired continuously by electronic instruments at six sites, one at Trenton, just upstream of the head of tidewater and at five sites in the estuary (fig. 4). The monitors at Chester, Pa., Fort Mifflin, Pa. and Benjamin Franklin Bridge were not operated from early December 1983 through the end of March 1984. At Ship John Shoal Lighthouse and Fort Mifflin the water was monitored for two parameters: temperature and specific conductance. At the remaining sites, the water was monitored for four parameters: temperature, specific conductance, dissolved oxygen, and pH.

Additional data were obtained monthly at ten sites between Torresdale and Marcus Hook, Pa. At each of these sites, water samples were collected at three points of the cross-sect ion. These samples were analyzed for tem perature, chloride, alkalinity, biochemical oxygen demand, specific conduc tance, dissolved oxygen, and pH.

Data obtained from the continuous monitoring sites were processed and stored for future reference by the U.S. Geological Survey, "fliey were also distributed regularly to cooperators and published annually lay the U.S. Geological Survey in "Water Resources Data for Permslyvania, Volume 1, Delaware River Basin". Data from the monthly sites were processed and stored by the City of Philadelphia Water Department.

The above-described programs were carried out in cooperation with the City of Philadelphia Water Department, Delaware River Basin Commission, Delaware River Master, and other agencies of federal, state, and county governments.

ESTUARINE WVTER-QUALITY DATA DURING 1984

The following is a summary and discussion of the data that were collected during the 1984 report year. Additional information can be found in the tables at the end of this section.

73

Streamflow

Streamflow is a vital factor in controlling the water quality of the estuary. Increased streamflow usually results in limiting salt-water intrusion and diluting the concentration of dissolved minerals, both of which contribute to a lower specific conductance and chloride level. Increased flow also aids in maintaining lower water temperature during warm weather and supporting higher dissolved-oxygen levels.

Based on streamflow records for the Delaware River at Trenton, N.J., mean monthly streamflow was lowest for the year during November (3,559 cfs) and highest for the year during April (34,900 cfs) (see table 9). The mean monthly streamflow was above the respective median for the period of record in December, February, and April through August, and below the median for January, March and September through November.

Temperature

The significance of water temperature in regard to water quality in the estuary lies in its profound influence on various physical, chemical, and biological properties of the water. In general, increases in water temperature have deleterious effects on water quality by lowering the saturation level of dissolved oxygen and increasing biological activities.

The primary factors involved in controlling water temperature in the estuary are climatic; however, various uses of the water by man can also have significant effects.

Based on records from Benjamin Franklin Bridge (Pier 11 North), Philadelphia, Pa., mean monthly temperatures April to November 1984 were below normal (based on the period 1962 to 1983) in April through September and above normal in October and November (see fig. 5).

Specific Conductance and Chloride

Specific conductance is the ability of a solution to conduct electri city. Basically, it can be used to measure the amount of ionized material in solution and relates approximately to dissolved-sol ids concentration.

Specific conductance values in bodies of water usually reflect the geochemistry of the drainage basin; however, pollution and the intrusion of oceanic salts can also have considerable effects. Increasing streamflows reduce the concentration of dissolved solids, thus lowering specific conductance and chloride concentrations. Conversely, decreasing flows have the opposite effects.

In the Delaware Estuary, the intrusion of oceanic salts is important to those who must use the estuary as a water supply. For this reason, chloride concentration is of great interest. Water with chloride con centrations in excess of 250 mg/L (milligrams per liter) is usually con sidered undesirable for domestic use and water with concentrations in excess of 50 mg/L is unsatisfactory for some industrial uses.

74

As sea water has a chloride concentration of approximately 19,000 mg/L the location of a body of water in relation to the sea can influence chloride concentrations in that body of water. For this reason, chloride con centrations in the Delaware Estuary generally increase with distance downstream toward the Delaware Bay and Atlantic Ocean.

Chloride concentration was not measured directly at Fort Mifflin, Pa. and Reedy Island Jetty, Del., but a correlation between specific conductance and chloride concentration has been developed based on analyses of water samples taken in the estuary. Chloride concentrations at those sites pre sented in tables 17 and 19 were derived from that relationship. The rela tionship is less reliable when chloride concentrations are lower than 30 mg/L because other ionized materials may be present in amounts large enough to affect the conductance-chloride relation. Therefore, chloride concentrations derived from specific conductance are not given when the relationship indica tes chloride concentrations of less than 30 mg/L. Chloride concentrations at Chester, Pa. were furnished by Scott Paper Company.

At Fort Mifflin, the maximum daily chloride concentration equaled or exceeded 50 mg/L 33 percent of the time (see table 17). The maximum was 111 mg/L on October 21. At Chester, the chloride concentrations equaled or exceeded 50 mg/L January 26 to February 16, March 13, August 31, and September 2 to November 30 and exceeded 250 mg/L September 26 to October 2, October 5 to November 13, November 15, and November 19 to November 30 with a maximum concentration of 640 mg/L on October 14 (see table 18). The maximum daily chloride concentration in the estuary at Chester was greater than 50 mg/L 31 percent of the time and greater than 250 mg/L 16 percent of the time (see table 18). Chloride concentrations in excess of 250 mg/L were recorded on all but 9 days at Reedy Island Jetty (see table 19) with concentrations in the range of 2,000 to 9,000 mg/L being common. The maximum concentration at this site was 9,280 mg/L on November 23.

Dissolved Oxygen

Dissolved oxygen is necessary in water for the respiration of aquatic organisms. It also plays a significant role in chemical reactions in aquatic environments. The major sources of dissolved oxygen in water are diffusion from the air and photosynthesis in aquatic plants. Dissolved- oxygen levels are limited by temperature, salinity, and the partial pressure of atmospheric oxygen.

Dissolved-oxygen levels in the estuary tend to be highest near Trenton and to decrease with distance downstream to a point near or somewhat downstream from the Benjamin Franklin Bridge where minimum values are usually reached.

75

During the past year, mean dissolved-oxygen concentration at the Benjamin Franklin Bridge was below 5 mg/L most days between May 7 and July 6, and con tinued below 5 mg/L for the period July 11 to November 30 (see table 20). Hie minimum daily mean was 0.5 on June 22. At Chester, the mean dissolved-oxygen concentration was below 5 mg/L on many days from June 9 through November 13 (see table 21). The lowest daily mean was 0.9 mg/L on July 2. Hie minimum hourly value was 0.2 mg/L on July 2. At Reedy Island Jetty, the minimum hourly value was 3.2 mg/L on July 5.

Figure 6 shows the frequency of hourly dissolved-oxygen concentration at Benjamin Franklin Bridge (Pier 11 North) and Chester during the critical summer period, July through September. During this period, the dissolved- oxygen concentration was below 4 mg/L 85 percent of the time at the Benjamin Franklin Bridge. Dissolved-oxygen concentrations were similar at the Benjamin Franklin Bridge in the 1983 and 1984 report years. Dissolved-oxygen con centration was below 4 mg/L only 16 percent of the time at Chester in 1983 as compared with 92 percent of the time in 1984.

Hydrogen-Ion Concentration (pH)

Hydrogen-ion concentration (pH) is fundamentally a measure of acidity or alkalinity. Values of pH below 7 indicate acidity, whereas values above 7 indicate alkalinity. In natural waters, pH generally ranges from 6.0 to 8.5. The main factors controlling the pH of a body of water are usually the geochemistry of the drainage basin and external influences such as pollution. Photosynthetic activity can also have a considerable influence on pH values. Increased photosynthetic activity (algal bloom) produces higher pH values. All pH values at Benjamin Franklin Bridge, Chester, and Reedy Island Jetty were within the range of 6.2 to 8.2. pH in the estuary tends to be lowest near Trenton, N.J., and to increase downstream.
