INTRODUCTION

The Water Resources Department of the St. Johns River Water

Management District has prepared this annual report for the water

year 1984 (October 1983 through September 1984). This report is

directed toward state, regional and local governmental units,

planning agencies, agricultural and business concerns, and inter-

ested members of the public; and is intended to provide

information on hydrologic conditions in the District.

The report is divided into two sections. The first section

deals with the status of the resource: 1. Rainfall, 2. Floridan

aquifer, 3. Surface Water, and 4. Water Use data. The second

section, the Appendices, contains rainfall statistics for 1951 to

1980 (the period used for calculating normal rainfall) and for

the available period of record, and a list of current technical

reports and papers available through the Department.

STATUS OF THE RESOURCE

Precipitation in the St. Johns River Water Management

District occurs primarily as rainfall. The isohyetal map of the

normal rainfall which is the annual mean for the period 1951-1980

is shown in Figure 1.

The annual rainfall variation in the District for the water

year 1984 is shown in Figure 2. Rainfall within the District

during the 1984 water year ranged from a low of 38.57 inches at

structure S-157 on Canal C-54, seventeen miles south of Melbourne

in South Brevard County, to a high of 78.90 inches at Orange City

in Southwest Volusia County. Average rainfall for the 1984 water

year calculated using the isohyetal map (Figure 2) was about 60.0

inches as compared to a District mean of 52.0 inches (based on

Figure 1) for the period of 1951-1980. The rainfall was above

normal for three consecutive years since the 1981 drought, the

mean rainfall for 1982 and 1983 being 62 and 55 inches,

respectively.

The departure from the normal rainfall for the 1984 water

year is illustrated on Figure 3. Rainfall was above normal

throughout most of the District. Portions of Alachua, Marion,

Lake, Brevard, Osceola, and Indian River counties received below

normal. Several areas received rainfall of 15 to 20 inches above

normal. In summary, rainfall for most of the District during the

1984 water year was greater than the average of 1951 - 1980,

which is the current normal.

Figures 4 and 5 display the potentiometric surface of the

Floridan aquifer during May and September 1984, respectively.

The change in potentiometric water levels between the normal

seasonal low in May and the seasonal high in September is shown

in Figure 6. While most areas of the District experienced a rise

in potentiometric levels between May and September, the levels in

the western portions of the District, Alachua, Baker, Bradford,

Clay, Marion, Putnam, Western Duval, and Nassau counties dropped.

The area of greatest rise in the Floridan potentiometric levels

occurred in Indian River, central Orange, and western St. Johns

counties. Table 1 summarizes the monthly and annual changes in

the Floridan potentiometric levels for selected observation wells

throughout the District.

Figure 7 shows the locations of four long-term monitor wells

in the District. The Alamana well, V-0101 in Volusia County,

showed little overall change in potentiometric levels during the

1984 water year (Figure 8). Potentiometric levels in Well D-

0160, at Neptune Beach in Duval County, dropped approximately 4

feet from February 1984 through September 1984. However, overall

levels from September 1983 to September 1984 remained nearly con-

stant with only a 0.40 foot rise. In the Brooklyn well, C-0120

at Keystone Heights in Clay County, the potentiometric level

dropped nearly 0.8 foot from September 1983 to September 1984.

The Platt well, BR-0645 near Melbourne in Brevard County, also

had decreasing potentiometric levels during Water Year 1984.

At the end of the water year, potentiometric levels in the Platt

well were approximately 1.6 feet lower in September of 1984 than

in September of 1983.

The Keystone Heights and Alamana wells are located in

recharge areas which are sparsely populated. Variations of water

levels in these two wells are the result of differences in

natural recharge and discharge. The overall decrease in poten-

tiometric levels at the Keystone Heights well indicates greater

discharge during the water year than recharge in the hydrauli-

cally connected areas down gradient in the Floridan aquifer. The

overall increase in potentiometric levels at the Alamana well

indicates greater recharge than discharge.

The Neptune Beach and Platt wells are located in areas of

high demands on the Floridan aquifer. The fluctuations in water

levels are directly affected by heavy ground water pumpage. The

Neptune Beach well reflects heavy urban withdrawals. The Platt

well reflects predominately agricultural demands.

The period of record trends of all 4 wells indicate slowly

dropping potentiometric water levels. The potentiometric levels

in the Platt well appears to have stabilized after 1981 or 1982.

The streams and rivers of the St. Johns River Water

Management District derive their flows from runoff of precipita-

tion and from ground water discharge. Locations of stream or

lake gaging stations used in the preparation of this report are

shown in Figure 9.

Figures 10 through 19 present monthly streamflow data for

water years 1982-1984 for selected gaging stations in the

District. Figures 20 through 29 show monthly elevations for some

principal lakes in the District. The median shown on these

figures indicates the flow (or stage) value equaled or exceeded

for 50 percent of time during the period of record. Overall

rainfall was about 15 percent above normal for the District

during the 1984 water year. In general, streamflow and lake

elevations are above median for most of the months. However,

because of relatively low rainfall conditions in the upper St.

Johns River Basin in 1984, the mean annual discharges at dif-

ferent locations in this basin are below those of 1982/1983

(Figs. 11-13, 15, and 16). A drawdown program was conducted on

Lake Griffin which is reflected by its 1984 elevations in Figure

28.

Table 2 presents the annual mean flow data for different

tributaries in the lower St. Johns River Basin.

Water use data are collected annually for the 19 counties

within the St. Johns Water Management District. Water use is

compiled for the following categories: Public Supply; Domestic

Self-Supplied; Industrial Self-Supplied (including

Institutional/Recreational Self-Supplied); Agricultural

Irrigation (including Livestock Use); Thermoelectric Power

Generation; Heat Pump/Air Conditioning; and Free-Flowing Wells.

The total fresh water use in the District for 1984 amounted to

1,507.05 MGD (Table 3) of which ground water totaled Ir217.04 MGD

(80 percent) and surface water 290.01 MGD (20 percent). There was

6.26 MGD of water reuse in the District for 1984 which was not con-

sidered in these figures. Of the 1,217.04 MGD ground water, 0.84

MGD was saline used in Reverse Osmosis for Public Supply.

The total population of the St. Johns River Water Management

District in 1984 was 2.575 million of which 79% was served by

public or private water suppliers. The monthly water use for

Public Supply in 1984 fluctuated from a peak in May of 377 MGD to

a low in January of 282 MGD (Figure 30). This increase in

pumpage is due primarily to lawn irrigation in the late spring

and early summer seasons.

For further details in water use refer to the "Annual Water

Use Survey: 1984", Technical Publication SJ 84-7 (see Appendix B).

Agricultural Irrigation was the largest fresh water use

category for 1984, accounting for 41% of the ground water used

within the District (Figure 31). The second largest category was

Public Supply using 26% of the fresh ground water. Other

categories with substantial amounts of ground water use were Heat

Pump/Air Conditioning (12%), Industrial Self-Supplied (11%), and

Domestic Self-Supplied (7%). Free-Flowing Wells accounted for

2%, and Thermoelectric Power Generation accounted for less than

1% (0.4%) of the total ground water used in 1984.

The major fresh surface water use category in 1984 was

Agricultural Irrigation, accounting for 90% of the total surface

water use. Public Supply, Industrial Self-Supplied, and

Thermoelectric Power Generation accounted for the remaining 10%

of total fresh surface water use (Figure 31) .

Brevard and Indian River counties were the largest users of

fresh water for 1984 (Table 4), accounting for 289.63 MGD (19%)

and 279.51 MGD (18.5%), respectively. Orange (183.08 MGD), Duval

(148.37 MGD), and Lake (143.88 MGD) counties were the next three

largest fresh water users. These five counties accounted for 69%

of the total fresh water use.

Brevard County, the largest fresh ground water use county in

1984, accounted for 259.97 MGD (21%). Other counties which

withdrew over 100 MGD of fresh ground water were Orange (152.86

MGD), Duval (144.71 MGD), Lake (125.87 MGD), and Indian River

(105.11 MGD). Indian River and Brevard counties' totals include

0.82 MGD and 0.01 MGD, respectively, of saline ground water used

for reverse osmosis.

Indian River County was the largest fresh surface water use

county in 1984, accounting for 174.40 MGD (60%). Other counties

using substantial amounts of surface water were Orange (30.22

MGD), Brevard (29.66 MGD), and Lake (18.01 MGD). Lake (2.52 MGD)

and Duval (1.56 MGD) counties used the largest amount of reuse

water (65%).

Figure 32 shows each county's fresh water use by source

(refer to Table 4 for actual values). Water use shown for those

counties partially within the SJRWMD (Alachua, Baker, Bradford,

Lake, Marion, Okeechobee, Orange, Osceola, and Polk) represents

the data from the St. Johns River Water Management portion only.

The remaining portions of those counties are not accounted for in

this report.

APPENDIX A

ANNUAL RAINFALL STATISTICS

The mean rainfall for 1951-1980 (the past three decades en-

ding in 1980) is considered as normal for a given gaging station.

However, other rainfall statistics, such as the median (value

equaled or exceeded for 50% of time), middle or normal range (the

range covered by the middle 50% of the annual rainfall values),

maximum and minimum during the record period, the lowest mean

annual rainfall (drought rainfall) for a specified period, etc.,

will be of interest for comparison with 1984 water year rainfall

data.

For several long term NOAA (National Oceanic and Atmospheric

Administration) stations located within and close to the

District, the foregoing rainfall statistics including drought

rainfall for 3-, 5-, and 10-year continuous periods are presented

in Table A-l for 1951-1980. In addition, Table A-2 considers all

rainfall data available through calendar year 1984 and presents

similar statistics.
