b-"1 THE DELTA BASINS

TheDelta area has beendivided into five basins. Theyare DrainageBasin No. 10, 32, 44A, 448 and 44C. The tidal characteristics of the De]ia area are dominantin the NorthDelta (Basin10), central De'lta(Basin 44A) and south Delta (Basin 44C) Basins. The areas west of the Delta (Basin aaB) drawwater foi irrigation mostly fr.omthe.Delta. The basin east of the Delta (Basin 32) contains water districts which drain from the eastside of the valte.f,tnto ttr6 Deltabasins.

TheDelta Basins that are influencedby tjdal action haveunique characteristics. Thesebasins containht'gh1y organjc soils andare typ'ica1'lyislands suryounded by channelsof water. Thesewaters are fed primari1V bV th-eSacramento and San JoaquinRiv_q.rs. Water in the Delta meandersthrough sioughs, cuts, canalsand channels. Thedirection of thes.eflows dependson inflow vblumes,tides, export pumping,.diversionsand other factors. Becauseof these characteristics,'the water bodies do not easily fit the descriptions in the In'landSurface Witers P'lan.

An argumentcan be madefor a separateclassification systemfor these Delta Basins. Fewwater bodies in theseBasins are agricultural suDplvor drainaoe dominated.Many of the channelsin the Delta hav-ebeen construiteO anO aieaoEa partial'ly for agricul.ture.but nonewould fal I into category (b) designati;n. Tt,qsgmajgr water bodies have not beenclassified as ca{eg6ry(l) bedauseof t tidal influencesand difficulties fitting theminto the clalsifitaiion scheme.

Category(b) Water Bodies The following information supports our list of waterbodies recommendedto be categortzedas Category b waterbodies as defined in the Iniand SurfaceWaters pian. These water bodies are shown on Figures 1 and 2. Kings Riven

The.Kings River begins-in the highest eievations of the SienraNevada in the northeastpart of the Tulare Lake Hydrologic Basin. It is dammed near piedra in the SierraNevada foothills to form Pine Elat Reservoir. From the reservoir, it fiows in a southwesteriy_ direction towards historic Tulare Lake. About one mile eastof where it meetsHighway 41, the River splits into North Fork and ClarLs Fork. At the Crescent Headworks, the North Foik continues into the which connectsthe Kings River to the San |oaq_uinRiver during flood periods. (The Basin Pian describesthe portion of the Frgsno blough from thett"r..rit i"aoworks to the Stiruon Weir as the North Fork.) The last eilnt miles of the Fresno Slough has beenreconstmcted and wili not be discussed-her". Approximateiv three miles downstream of the North Fork/Clartcs.Fork :piit tfre'S'outfrr.if;pfil- from the Clarks Fork. The South Fork and Clarks Forli reconverge five milds Jo*r**",",. Kings River peoples lhe downstrea:n of weq,_excfr$.g the Fresno slough, is {omiryted by agn:ilt'rd supply flows from Marctr ,t-igh eugus; J-"n y""r. Aquatic resourc€s in these readres are enhanced due to thise flows. "d*ltu"l The Lower South Fork is dominated from Septenrber through February by a ground (use.d mix of water for irrigation) and agricuitural disctrargL. a"" idr"ti. resourc€spresent in the Lower south Foik of the Kings Riier oiri *iv as a result of theseagriculturai flows.

The FresnoSiough is normally dry:xcgpt for flood periods when it convevsKings River water out of the Tulare Lake Basin. During outo periocis, the Slough receives small quantities of agricultural dischargeswhictr"percoiaie q*;klii;;;" bed' Any stream aquatic resourcesPresent in the slough during periods br low precipitation exist oniv as a resuit of thesedischarges.

EastsideSheams:

Eastside streamsare ephemeraland have water after rainfall events. Several streamson the eastsicie of Fresnoand Tu-larecounties mav be ciominated ,,frost hrate.r" bv dunng winter months. Thesestrearru inciude wahtoke c;k,-i;"i;";; Creek,and sand Creek. "Frost water" is well water used to pr""""i tir" otrus from freezing crop during partio.riarlvcold days. The "frost water,,mav contains a agrimlturai chemicaisused in the citrus orchards.

ws1 TULARE LAKE BASIN

Traver Creek is normaiiy dry except for flood periods. It currentiv carries agrictrlfr-ud supply warer from the Kings River during the irrigation seasonand may carry "frost water" during cold spells. Any aquatic resourcesPresent in this creek during periods of no precipitation exist only as a result of the suppiv flows.

Kaweah Riven

The Kaweah River svstem (which indudes the St. Iohns River, Elk Bavou, Outside Creek, Deep Creek, Elbow Creek, Cottonwood Creek, and Cross Creek) beiow is fuIiy appropriated. Except during flood periods, it is dry river bed or dominated by agricuifiuai suppiy flows during the irrigation season.

Poso Creeic

Poso Creek originates in the Sierta foothills and flows into the valley floor in the general direction of the Tuiare Lake Bed. On the valley t'loor, it is an uncontrolied lphemeral stream which flows only during periods of intense preciP_itation. The North Kern Water Storage District uses the lower reach of the channel for ground water recharge with Kern River water. Any aquatic resources Present in this reach of the creek is the result of these flows.

Buena Vista Aquatic Recreation Area:

The is the natural terurinus of the Kern River. Aquatic iakes and regulation-of along the edge of the old lake bed are now used for limited _storage irrigition *iters from the Kern River, the Cdifornia Aqueduct,_and some ground *"tlt. All beneficial uses at these lakes are derived from these flows;

Kings Riven

The Kings River historicallv distributes into multiple channels as it enters the vailev t-ioor. These channels, now reconsfmcted and with headgatry are ciry except for agricuirural suppiv flows. The reconstructed charmeis indude China Slough, phi1ilps Ditch, Carmeiita Ditch, Rice Ditch, Short Ditch #1, Mclaughitl Ditch, Farm Ditch #1 and #3, Jacobi Ditch, Fink Ditch, Turner Ditch, Hanke Ditch, Bwd Ditch, jack Ditch, Cameron Ditch, and Harris Slough Ditch'

At the end of the Kings River, the Fresno Slough rraditionailv carried Kings_River. water out of the Tularl Lake Basin and into the San ioaquin River svstem' Since the Fresno Slough Bvpass was constructed, the Fresno Slough has been dry excePt for agricuitural supiiy water from the Mendota Pooi and smaii arnounts of Kings River water.

Kaweah Riven

The Kaweah River historically distributes into multiple channets as it enters the valley floor. Some of these channels remain naturaland some have been reconstmcted. Reconstructed drannels include the Bates Slough, tewis Creek, Inside Creek' Mill Creek, and Casteron Creek. These ciranneis]J--""p, t , Creek, are dominat"d by."rr*l.trral supply waters. Mill Creek, at differeni ti-o of the year, mav be donlnaLed bv agricultual supply waters or domestic and indpstrial wastewater from facilities in Visalia
