Mitigation OptionsOn-road Fleet Emissions Mitigation Select "2010 and Newer On-road Vehicles Fleet" option when the on-road heavy-duty truck fleet for the project will be limited to vehicles of model year 2010 or newer

Off-road Equipment Emissions Mitigation

Select "Tier 4 Equipment" option if some or all off-road equipment used for the project meets CARB Tier 4 Standard

Will all off-road equipment be tier 4?

The remaining sections of this sheet contain areas that require modification when 'Other Project Type' is selected.

No Mitigation

No MitigationSelect "20% NOx and 45% Exhaust PM reduction" option if the project will be required to use a lower emitting off-road construction fleet. The SMAQMD Construction Mitigation Calculator can be used to confirm compliance with this mitigation measure (http://www.airquality.org/ceqa/mitigation.shtml).

Note: Required data input sections have a yellow background.

Mitigation OptionsOn-road Fleet Emissions Mitigation Select "2010 and Newer On-road Vehicles Fleet" option when the on-road heavy-duty truck fleet for the project will be limited to vehicles of model year 2010 or newer

Off-road Equipment Emissions Mitigation

Select "Tier 4 Equipment" option if some or all off-road equipment used for the project meets CARB Tier 4 Standard

Will all off-road equipment be tier 4?

No Mitigation

No MitigationSelect "20% NOx and 45% Exhaust PM reduction" option if the project will be required to use a lower emitting off-road construction fleet. The SMAQMD Construction Mitigation Calculator can be used to confirm compliance with this mitigation measure (http://www.airquality.org/ceqa/mitigation.shtml).

Subject: List of threatened and endangered species that may occur in your proposed projectlocation, and/or may be affected by your proposed project

To Whom It May Concern:

The enclosed species list identifies threatened, endangered, proposed and candidate species, aswell as proposed and final designated critical habitat, under the jurisdiction of the U.S. Fish andWildlife Service (Service) that may occur within the boundary of your proposed project and/ormay be affected by your proposed project. The species list fulfills the requirements of theService under section 7(c) of the Endangered Species Act (Act) of 1973, as amended (16 U.S.C.1531 ).et seq.

Please follow the link below to see if your proposed project has the potential to affect otherspecies or their habitats under the jurisdiction of the National Marine Fisheries Service:

http://www.nwr.noaa.gov/protected_species/species_list/species_lists.html

New information based on updated surveys, changes in the abundance and distribution ofspecies, changed habitat conditions, or other factors could change this list. Please feel free tocontact us if you need more current information or assistance regarding the potential impacts tofederally proposed, listed, and candidate species and federally designated and proposed criticalhabitat. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of theAct, the accuracy of this species list should be verified after 90 days. This verification can becompleted formally or informally as desired. The Service recommends that verification becompleted by visiting the ECOS-IPaC website at regular intervals during project planning andimplementation for updates to species lists and information. An updated list may be requestedthrough the ECOS-IPaC system by completing the same process used to receive the enclosed list.

The purpose of the Act is to provide a means whereby threatened and endangered species and theecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2) of theAct and its implementing regulations (50 CFR 402 ), Federal agencies are required toet seq.

07/07/2017 Event Code: 08ESMF00-2017-E-06950 2

utilize their authorities to carry out programs for the conservation of threatened and endangeredspecies and to determine whether projects may affect threatened and endangered species and/ordesignated critical habitat.

A Biological Assessment is required for construction projects (or other undertakings havingsimilar physical impacts) that are major Federal actions significantly affecting the quality of thehuman environment as defined in the National Environmental Policy Act (42 U.S.C. 4332(2)(c)). For projects other than major construction activities, the Service suggests that a biologicalevaluation similar to a Biological Assessment be prepared to determine whether the project mayaffect listed or proposed species and/or designated or proposed critical habitat. Recommendedcontents of a Biological Assessment are described at 50 CFR 402.12.

If a Federal agency determines, based on the Biological Assessment or biological evaluation, thatlisted species and/or designated critical habitat may be affected by the proposed project, theagency is required to consult with the Service pursuant to 50 CFR 402. In addition, the Servicerecommends that candidate species, proposed species and proposed critical habitat be addressedwithin the consultation. More information on the regulations and procedures for section 7consultation, including the role of permit or license applicants, can be found in the "EndangeredSpecies Consultation Handbook" at:

http://www.fws.gov/endangered/esa-library/pdf/TOC-GLOS.PDF

Please be aware that bald and golden eagles are protected under the Bald and Golden EagleProtection Act (16 U.S.C. 668 ), and projects affecting these species may requireet seq.development of an eagle conservation plan(http://www.fws.gov/windenergy/eagle_guidance.html). Additionally, wind energy projectsshould follow the wind energy guidelines (http://www.fws.gov/windenergy/) for minimizingimpacts to migratory birds and bats.

Guidance for minimizing impacts to migratory birds for projects including communicationstowers (e.g., cellular, digital television, radio, and emergency broadcast) can be found at:http://www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/towers/towers.htm;http://www.towerkill.com; andhttp://www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/towers/comtow.html.

Environmental Compliance Report

Project: Phoenix Lake Preservation and Restoration Project

Activity: Plant survey

Surveyor(s): Robin Hunter, Kevin Fisher

Date: May 31, 2017

Time: 10:45 AM – 11:30 AM

Weather: Overcast, 65-70°F, calm

Methods: The Rare Plant Survey Area consists of the wetland area within the north orchard (Figure

1), which is the area within the Project that would be subject to disturbance and could also potentially

support rare plants. The entire Rare Plant Survey Area was systematically walked in meandering transects.

Plant species encountered were identified to the taxonomic level required to determine whether the plant

was a special-status taxon. This survey was within the bloom period the special-status plant species with

potential to occur within or adjacent to this habitat: yellow-lip pansy monkeyflower (Diplacus pulchellus

[=Mimulus pulchellus]) and stinkbells (Fritillaria agrestis).

Results: No special-status plants were observed. A list of all plant species encountered during the

survey is provided in Attachment A.

Special-status species observed (if any): None.

Notes: None.

1.2.1 State of California Regulations

CEQA and State CEQA Guidelines

The proposed project must comply with California Environmental Quality Act (CEQA) (PublicResourcesCode[PRC]21000etseq.andtheCEQAGuidelines(CaliforniaCodeofRegulations[CCR],Title14,Chapter3),whichdetermine,inpart,whethertheprojecthasasignificanteffectonauniquearchaeologicalresource(perPRC21083.2)orahistoricalresource(perPRC21084.1).

Determinedbyaleadstateagencytobehistoricallysignificant.

CEQAGuidelines CCR15064.5 also applies to unique archaeological resources as defined in PRC21084.1.

AssemblyBill(AB)52,whichwentintoeffectonJuly1,2015,requires,perPRC21080.3.1,thatCEQAlead agencies consultwith a California Native American tribe that is traditionally and culturallyaffiliatedwiththegeographicareaofaproposedproject,ifsorequestedbythetribeandiftheagencyintendstoreleaseanegativedeclaration,mitigatednegativedeclaration,orenvironmentalimpactreportforaproject.Thebillalsospecifies,underPRC21084.2,thataprojectwithaneffectthatmaycauseasubstantialadversechangeinthesignificanceofatribalculturalresource(TCR)isconsideredaprojectthatmayhaveasignificanteffectontheenvironment.ThislatterlanguagewasaddedtotheCEQAchecklist inAugust2016.TUD, as theproject’sCEQA leadagency,will consultwithNativeAmericantribespursuanttoPRC21080.3.1.

The CRHR includes all properties listed, or determined to beeligibleforlisting,intheNationalRegisterofHistoricPlaces(NRHP),includingpropertiesevaluatedunder Section 106 of the National Historic Preservation Act (NHPA). The criteria for listing aresimilartothoseoftheNRHP.CriteriaforlistingintheCRHRincluderesourcesthat:

2) Areassociatedwiththelivesofpersonsimportantinourpast;

3) Embodythedistinctivecharacteristicsofatype,period,region,ormethodofconstruction,orrepresenttheworkofanimportantcreativeindividual,orpossesshighartisticvalues;or

4) Haveyielded,ormaybelikelytoyield,informationimportantinprehistoryorhistory.

The regulations set forth the criteria for eligibility as well as guidelines for assessing historicalintegrityandresourcesthathavespecialconsiderations.

TheimplementingregulationsoftheNHPArequirethatculturalresourcesbeevaluatedforNRHPeligibility if they cannot be avoided by an undertaking (proposed project). To determine sitesignificancethroughapplicationofNRHPcriteria,severallevelsofpotentialsignificancethatreflectdifferent(althoughnotnecessarilymutuallyexclusive)valuesmustbeconsidered.AsprovidedinTitle36CFRSection60.4,“thequalityofsignificanceinAmericanhistory,architecture,archaeology,andcultureispresentindistricts,sites,buildings,structures,andobjectsthatpossessintegrityoflocation,design,setting,materials,workmanship,feeling,andassociation”andmustbeconsideredwithinthehistoriccontext.Resourcesmustalsobeatleast50yearsold,exceptinrarecases,and,tomeeteligibilitycriteriaoftheNRHP,must:

Extensive archaeological research in associationwith the constructionofNewMelonesDamandReservoir, located justwestof Sonora,provides themost in‐depth, region‐specific archaeologicaldata in close proximity to the project area. Studies at New Melones revealed broad periods ofoccupation,whichhavebeendefinedbychronologicalphases,inthisportionoftheStanislausRiverwatershed(Moratto2002).

2.3 Ethnohistoric Context The“Miwok”(alternativelyknownasthe“Miwuk”or“Me‐Wuk”)refertoalargeexpanseofpeoplewho were related through language and who occupied a vast region of central and northernCalifornia,fromthePacificCoast,eastthroughtheSacramento‐SanJoaquinDelta,andsouthalongthefoothillsoftheSierraNevadamountainrangetotheFresnoRiver.AlfredKroeberidentifiedthree“territorially discrete” groups of theMiwok: the Coast Miwok, LakeMiwok, and InteriorMiwok(Kroeber1925:442).Levy(1978)furtherdividestheInteriorMiwokintofivesub‐groups:theBayMiwok,thePlainsMiwok,theNorthernSierraMiwok,theCentralSierraMiwok,andtheSouthernSierraMiwok.Basedon theirhistoryand similarities, theNorthern,Central, andSouthernSierraMiwokgroupsformaSierraMiwoklanguagegroup,differentthanthelanguagegroupsoftheCoastal,Bay,andPlainsMiwok(Levy1978:398).TheCentralSierraMiwokoccupiedtheupperStanislausandTuolumneRiverwatershedsaboveapproximately200feetabovesealevel,includingtheportionoftheSullivanCreekwithintheprojectarea,atthetimeofEuropeancontact.



The principal political unit of the Miwok was the tribelet. According to Levy (1978:398), “eachtribeletwasanindependentandsovereignnationthatembracedadefinedandboundedterritoryexercisingcontroloverthenaturalresourcescontainedtherein.”Eachtribeletconsistedofseveralsemi‐permanent inhabited settlements and a larger number of annually inhabited seasonalcampsites.CentralSierraMiwokvillagesconsistedofavarietyofbuilidings, includingcedarbarkhomes (umachas), acorn granaries (chakka), and large semi‐subterranean ceremonial houses(roundhouses,orhangi)(TuolumneBandofMe‐Wuk2016).Otherstructuresthatwereusedinthelowerelevationsorduringthesummerincludedaconicalhouseoftulemattingandacircularbrushstructureforceremonies(Levy1978:408‐9).

TheSierraMiwokhad,andcontinuetohave,extensiveknowledgeaboutthenaturalresources intheir ancestral territory. Annual intentional burning of grasses insured an abundance of seed‐producingannualsandampleforagingfordeer.TheSierraMiwokseasonallycollectedresourcesatboth higher and lower elevations to obtain foods not found in the vicinity of their permanentsettlements. The gathering ofwild plant foods included several highly prized varieties of acorns(interiorliveoak,blueoak,andblackoak),nuts(buckeye,hazelnut,greypineandsugarpine),seeds,roots,andgreens.TheSierraMiwokprimarilyhunted themuledeer,butalsohuntedblackbear,grizzlybear,andvalleyquail,aswellasaquaticresources includingseveral fowland fishspecies(Levy1978:402‐5).

The SierraMiwokmanufactured both coiled and twined basketry. The basketrywas stylisticallysimilartotheYokutsandNumic‐speakingpeopleslocatedeastoftheSierraMiwok.(Levy1978:405‐8).Approximately20differenttypesofbasketswereused(TuolumneBandofMe‐Wuk2016).

TheSpanishfirstmadecontactwiththeCentralSierraMiwokduringexpeditionstotheSacramento‐SanJoaquinValleyin1806(TuolumneBandofMe‐Wuk2016).TheSierraMiwoklargelyescapedthedirect ramifications of the Spanish mission period and the Mexican rancho era, which sodevastatinglyaffectedtheirMiwok‐speakingrelativesintheSanFranciscoBay,Delta,andCentralValleyregions,andtheirNorthernYokutsneighborstothewest.However,theinfluxofforeignersduringtheCaliforniaGoldRushbeganaperiodofforcibleremovalfrommanyoftheirtraditionalresources.ThiswasexacerbatedwhenCaliforniabecamepartoftheUnitedStatesin1850andthesubsequentarrivaloftheU.S.Government.TreatiessignedbymembersoftheSouthernSierraMiwoktribeletswereneverratifiedbytheUnitedStatesSenate(Levy1978).SomeoftheSouthernSierraMiwokwereremoved to theFresnoarea, thoughmostof themremained in rancheriasscatteredthroughouttheSierraNevadafoothills.Miwokslivingontherancheriasduringthelatterhalfofthenineteenthcenturyandtheearlypartof thetwentiethsubsistedpartlybyhunting/gatheringandpartlythroughseasonalwagelaboronfarmsandranchesinthefoothillareas(Levy1978:401).TheMiwok were initially involved in gold mining operations during the Gold Rush before relationsbetweentheSouthernSierraMiwokandAmericanandEuropeanminersbecamehostile.TherearerecordsofSouthernSierraMiwoksupplyinglaborforlargeminingoperations,alongwithevidenceto indicate the deaths of at least 200 Miwok by miners during the period 1847–1860 (Levy1978:401).

Intheearlypartofthetwentiethcentury,anumberofsmallparcelsofland(rangingfrom2tomorethan300acres)wereacquiredbythefederalgovernment(throughexecutiveorderorbypurchase)asreservationsforsomeoftheindividualslivingonrancherias.Thisincludednearly300acresoflandsfortheTuolumneMiwok.Sincethattime,theTuolumneBandofMe‐Wukhasgrownitslandbase and has become a strong political and business entity within Tuolumne County. The tribeopenedtheBlackOakCasino in2001andsince thenhasusedtheproceedsof thevenuetobuild

2.4 Historic‐Era Context TuolumneCountywaswelloutsideofthecoastalareasofCaliforniainitiallycolonizedbytheSpanishinthelate1700sandearly1800s.However,GabrielMoragaledanexplorationpartythroughthewesternportionofthecountyin1806(Kyleetal.2002).Butitwasn’tuntiltheadventoftheGoldRushthatEuropeanandEuro‐AmericanpopulationexplodedinTuolumneCounty.Reportedly,goldwasfirstdiscoveredinthecountybyapartyledbyJamesWoodalongabranchoftheTuolumneRiver(nowknownasWoodsCreek)nearpresent‐dayJamestowninthesummerof1848.Thenewsspread rapidly, and numerousmining camps, including those at Columbia and Sonora, had beenestablishedintheregionbytheendoftheyear.WoodsCreekissaidtohave,ultimately,containedmoregoldthananycreekofitssizeinthestate(Kyleetal.2002).SonoraCamp,asitwasknownintheearlyyears,wasestablishedbyagroupofMexicanswhocamelookingforgold.Bythefollowingsummer,thetownhadgrownto5,000,comprisedmostlyofMexicanandChileannationals(Kyleetal.2002).ThepopulationoftheCountyquicklypassed250,000by1853(TuolumneCountyHistoricalSociety2017).

GoldminingintheregionfollowedthetrajectoryoftheentireMotherLodeandothergold‐richareasofthestate.Theeasily‐accessibleplacerminesplayedoutquickly.Throughinnovation,theuseofpansevolvedtorockers,andthensluiceboxes,asminersengineeredthecreeksandriverbottomstoreachdeepergold‐bearinggravels.Hydraulicminingbecametheprimarymethodofgoldmininginthe1860s,aslarge‐nozzlehoseswereusedtowashawaywholehillsidestoaccessthegolddeposits.TheStateprohibitedhydraulicmininginthe1880sduetotheenvironmentaldamagecausedbytheamountofdebriswasheddownthecreeksandrivers.Hardrockmininganddredgingthenbecamethepreferredmethodsofgoldextraction.

Water is essential to goldmining andwithout a reliablewater source, goldmining in the SierraNevada foothills was a seasonal endeavor. Thus, as gold mining expanded and new areas wereexploited,extensivewaterstorageanddistributionsystemsweredevelopedintandem.By1858,itwasreportedthatTuolumneCountycontained181milesofcanalsandditches.FoothillandFrancis(2012)haveprovidedadetailedchronologyofthemyriadwatercompaniesthatlaidthefoundationfortheTUD,andthereaderisreferredtothatreportforin‐depthinformationonthetopic.

Relatively short ditcheswere developed early on to supplywater to specific diggings, primarilyaroundColumbia,butitwasquicklyrecognizedthatmoreelaborateoperationswouldberequiredtobringwatertowholeareasthatwerebeingactivelymined;potablewaterwasalsoneededforthecommunitiesthathadbeenestablished.TheTuolumneCountyWaterCompany(TCWC),formedin1851, was one of the first water companies in the County to incorporate “for the purpose ofdevelopingandconservingthewateroftheStanislausRiverandconveyingittothevariousminersin Tuolumne County” (Foothill and Francis 2012:3.3). The first section of flume and canal wasconstructed between Lyons Ranch and Columbia. Completed in 1852, the system began on “theStanislausRiverabout10milesaboveStrawberryStationontheMonoRoad(StateRoute108)…thesystemfollowedthechanneloftherivertoBulkHeadbelowLyonsFlatDamandbyditchandflumetoColumbia,Springfield,ShawsFlat,andMontezuma”(FoothillandFrancis2012:3.4).Itconsistedofabout18milesofflume,30milesofearthenditch,andfoursmallreservoirs,andadiversiondamatLyonsFlat.Althoughtherehavebeensomemodifications,thissystemisstillinusetoday(FoothillandFrancis2012:3.7).



AccordingtoFoothillandFrancis(2012:3.13):

FormorethanhalfacenturytheTuolumneCountyWaterCompanywasthedominantplayerinthebuildingofdams,reservoirs,andditchesandthedeliveryofwatertothenorthernportionofthecounty.Duringthisperiodthecompanyabsorbed,bymergerorpurchase,morethan40othercompaniesincorporatedbetween1851and1907,about 20 of which were integrated into later systems… The systems wereconstructed,reused,connected,enlargedandimproved,altered,andabandoned,firstby the TCWC in 1851‐1898, the Columbia and Stanislaus River Water Company(1855‐1860),theTuolumneHydraulicAssociationanditssuccessors(1852‐1876),andtheSullivanCreek/Street’s/Shaw’sFlatsystem(1855‐1876),andothers.

ManyoftheseditcheswerepurchasedandconsolidatedbytheTuolumneHydraulicMining Company… in 1872 and sold to the TCWC in 1876... Thereafter, the ditchsystemswerebundledandtransferredtotheTuolumneWaterandElectricPowerCompany in1898, theTuolumneWaterPowerCompany in1907, reformedas theSierraandSanFranciscoPowerCompanyin1909,PacificGas&ElectricCompanyin1927,CountyofTuolumneinthe1980s,andtheTuolumneUtilitiesDistrict,formedin1992.

ConstructionandownershipofPhoenixLake,similarly,hasaconvolutedpast.Referencesindicatethatthedamandreservoirwereoriginallyconstructedin1853or1854bytheTuolumneHydraulicAssociationortheSullivan’sCreekandTuolumneWaterCompany,respectively(FoothillandFrancis2012:4.3;PhoenixLakeTaskForce [PLTF]2010:3).Thereservoirwaspurchasedby thePhoenixWaterCompanyin1859,alongwiththeditchesownedbytheShaw’sFlatandTuolumneRiverWaterCompany(FoothillandFrancis2012:4.31),andhenceforthwascalledthePhoenixReservoir.Thecontemporary damwas completed in 1880 following a storm event in 1862 that destroyed theoriginaldamsystem(PLTF20104).Bythattime,thereservoirandditcheswereunderthecontroloftheTCWC.

Asgoldminingdiminishedintheregion,thewaterstoredinPhoenixLakewasusedforagricultureandpotablewaterforSonora,andthelakeitselfbecameapopularrecreationarea.ThisresultedintheestablishmentofPhoenixLakeParkinthemid‐1920s.Todaythereservoirhaslimitedaccessbythepublic,butisenjoyedbyhomeownerswholiveadjacenttothelake(TUD2017),primarilytothesouthandeast.

Phoenix Lake Dam

Phoenix Lake Dam, which impounds Phoenix Lake/Reservoir, consists of an earthen dam andreinforced concrete spillway. References indicate that the dam and reservoir were originallyconstructed in1853or1854by theTuolumneHydraulicAssociationor theSullivan’sCreekandTuolumneWaterCompany,respectively(FoothillandFrancis2012:4.3;PLTF2010:3), tosupporthydraulicmining.By the late1870s, itwasalso thesourceofwater for the townsofSonoraandJamestown(FoothillandFrancis2012).Thecontemporarydamwascompletedin1880followingastormeventin1862thatdestroyedtheoriginaldamsystem(PLTF2010:4)

A third resource, Phoenix Ditch, hadpreviouslybeenrecordedintheprojectstudyarea.Noneoftheseresourceswillbeimpactedbytheproposedproject,ascurrentlydesigned.Thedamisnotscheduledtobealteredandtheditch,whichislikelyburiednexttoSummersPond,maybecoveredbyadditionalfillmaterial.TheminesiteisoutsidethedefinedprojectAPE.

TheremovalofsedimentfromPhoenixLakewillnotgobelowthedepthofthedepositedsedimentsandwill not impact original ground; therefore, it is not anticipated that archaeologicalmaterialswould be uncovered during sediment removal. Furthermore, no archaeological materials wereidentifiedintheremainderoftheprojectarea.However,thereisalwaysthepossibilitythatburiedcultural materials will be uncovered during construction activities. If prehistoric or historic‐eramaterials are encountered, all work in the vicinity of the finds should halt until a qualifiedarchaeologist canevaluate thediscoveryandmakerecommendations inaccordancewith36CFRSection800.13(b).Prehistoricmaterialswouldmostlikelyincludeobsidianandchertflaked‐stonetools (e.g., projectile points, knives, choppers), tool‐making debris, ormilling equipment such asmortarsandpestles.Historic‐eramaterialsmightincluderemainsofagriculturalimplements;stoneorconcretefootingsandwalls;anddepositsofmetal,glass,and/orceramicrefuse.

Thepossibility of encounteringhuman remains also cannotbediscounted. Section7050.5 of theCaliforniaHealth and Safety Code states that it is amisdemeanor to knowingly disturb a humanburial. Ifhumanremainsareencountered,workshouldhalt inthevicinityof theremainsand,asrequired by law, the Alameda County coroner should be notified immediately.

Re: Phoenix Lake Preservation and Restoration Project

To Whom It May Concern,

A record search of the sacred land file has failed to indicate the presence of Native American cultural resources in the immediate project area. The absence of specific site information in the sacred lands file does not indicate the absence of cultural resources in any project area. Other sources of cultural resources should also be contacted for information regarding known and recorded sites. Enclosed is a list of Native Americans individuals/organizations who may have knowledge of cultural resources in the project area. The Commission makes no recommendation or preference of a single individual, or group over another. This list should provide a starting place in locating areas of potential adverse impact within the proposed project area. I suggest you contact all of those indicated, if they cannot supply information, they might recommend others with specific knowledge. By contacting all those listed, your organization will be better able to respond to claims of failure to consult with the appropriate tribe or group. If a response has not been received within two weeks of notification, the Commission requests that you follow-up with a telephone call to ensure that the project information has been received. If you receive notification of change of addresses and phone numbers from any of these individuals or groups, please notify me. With your assistance we are able to assure that our lists contain current information. If you have any questions or need additional information, please contact me at (916) 373-3712. Sincerely, Joshua Standing Horse Associate Governmental Program Analyst

P3a continued: Phoenix Lake Dam, which impounds the waters of Sullivan Creek and two tributaries, Power and Chicken Creeks, to form Phoenix Lake/Reservoir, consists of an earthen dam and reinforced concrete spillway. References indicate that the dam and reservoir were originally constructed in 1853 or 1854 by the Tuolumne Hydraulic Association or the Sullivan’s Creek and Tuolumne Water Company, respectively (Foothill and Francis 2012:4.3; PLTF 2010:3), to support hydraulic mining. By the late 1870s, it was also the source of water for the towns of Sonora and Jamestown (Foothill and Francis 2012). The contemporary dam was completed in 1880 following a storm event in 1862 that destroyed the original dam system (PLTF 2010:4)

The dam was described in 1909 as being 1,150 feet long and 40 feet high. In 1916, it was described as “an earth-filled dam with a total crest length of 910 feet and an average height of 3 feet, a concrete retaining wall and rubble masonry and concrete spillway… with flash boards; the submerged area was 105 acres. The outlet consisted of two parallel discharge pipes through the levees, set in concrete.” (Foothill and Francis 2012:4.32). The dam has clearly undergone some modifications over time, as today the structure is 795 feet in length, 52 feet high, 10 feet wide, and covers approximately 76 acres (DSOD 2017).

The reservoir originally supplied water to the Curtis Creek (now Phoenix), Sonora, and Shaw’s Flat ditches to support mining operations (Foothill and Francis 2012). Each of these ditches appear to contributing elements to a potential Tuolumne Utilities National Register District (Foothill and Francis 2012).

Features (Number, briefly describe, indicate size, list associated cultural constituents, and show location of each feature onsketch map.): Feature 1 is a prospect pit or collapsed mineshaft measuring 25 feet (NW/SE) x 20 feet (NE/SW) and isapproximately 20 feet in depth. The center of Feature 1 was designated as the site datum. No shaft entrance is visible at the baseof the pit and is assumed to have been in-filled or collapsed; the volume of a nearby tailings pile (Feature 2) appears to containmore material than the pit could contain. Feature 2 is a tailings pile oriented to the southeast and downslope of Feature 1 andmeasures 55 feet (NW/SE) x 40 feet (NE/SW) and has a maximum height in the southeast of approximately 20 feet. Structure 1 isconstructed of wood framing and corrugated metal sheets fastened with wire nails; the foundation is constructed of pylonsconsisting of molded concrete blocks measuring approximately 15 inches square and 8 inches high. These blocks are stacked andmasoned together in courses of various heights to level the structure across the top of Feature 2 and the southeast-trending hill;the number of courses ranges from a just a few in the west corner of the structure to more than 10 courses in the east corner. Thefootprint measures 16 feet (NE/SW) x 26 feet (NW/SE); the apex of the gabled roof is 16 feet high. The roof has been crushed inthe south corner, likely from a falling tree limb. Structure 2 is located north of Structure 1 and is similar in design and construction.Structure 2 measures 14 feet (NE/SW) x 16 feet (NW/SE) and sits on a rock foundation constructed of local boulders of unknowntype. A scatter of metal debris surrounds the base of the structure and includes threaded metal rods and nuts, machinery parts ofunknown function, and a crushed, rusted condensed milk can.

Most of the site is situated on a relatively level hilltop which slopes down in the southeastern tip of the site with on-site vegetation including manzanita, grey and ponderosa pine, and native/seasonal grasses. Aspect is to the south, slope varies from 0-35º, and exposure is 90%. The site is in good condition, with potential impacts from pedestrian activities associated with a trail that leads directly to the site. Two modern picnic tables at the site appear to have been recently installed, along with signage attached to trees near Feature 1 reading "Warning/ Do not lean over or clime [sic]".

*A5. Cultural Constituents (Describe and quantify artifacts, ecofacts, cultural residues, etc., not associated with features.): Culturalconstituents consist of a debris scatter of non-diagnostic metal machinery parts and fragments, along with a single crushedcondensed milk can.

*A6. Were Specimens Collected? No Yes (If yes, attach Artifact Record or catalog and identify where specimens are curated.)*A7. Site Condition: Good Fair Poor (Describe disturbances.): A trail leads to the site and modern picnic tablesand signage have been recently installed.*A8.
