. f}fl07::ig . included in Appendix B: . FIDrida Farmers Ditch FIDrida Canal Harris PattersDn Ditch PiDneer Ditch McClure-Murray Ditch . These ditches deliver water fDr 93 percent Df the lands irrigated in the FlDrida River basin, excluding the Salt Creek area. The FIDrida Canal is IDcated abDut 1.8 miles upstream Df the Florida Farmers Ditch. The FIDrida Canal and the FIDrida Farmers Ditch are used fDr deliveries Df irrigation water tD the FIDrida Mesa. Since the natural flDW Df Salt Creek is negligible, the water supply fDr ilTigated areas alDng Salt Creek is diverted frDm the LDS PinDs River, as described belDw. The remaining irrigated areas are supplied by a number Df small irrigatiDn ditches alDng the Florida River and its tributaries. . . Transbasin DiversiODS from Los Pinos River A pDrtiDn Df the water diverted frDm the LDS PinDs River by the RDbert MDrrisDn Ditch and King CDnsDlidated Ditch is delivered tD the Salt Creek basin, a tributary Df the FIDrida River. DiversiDns intD the Salt Creek basin have cDntinued thrDughDut the 30 year study periDd fDr irrigatiDn Df abDut 3,100 acres. RecDrds are available fDr the tDtal diversions frDm the Los Pinos River by RDbert MDrrison and King CDnsDlidated ditches, but nD recDrds have been kept tD indicate the amDunt of water that has been delivered intD the Salt Creek basin. The transbasin diversiDns are reflected in the Salt Creek gage recDrds fDr the 20 year periDd of record including 1957 thrDugh 1963 and 1968 thrDugh 1980. The annual flDW Df Salt Creek varied from 1,200 tD 12,500 acre-feet during the 20 year period Df recDrd, almDst all Df which was attributable tD water impDrted frDm the LDS PinDs River~ DiversiDns thrDugh the RDbert MorrisDn and King CDnsDldiated ditches varied frDm 22,100 tD 56,600 acre-feet per year during the same period, as shown by the summaries Df diversion records in Appendix B. The cDrrelatiDn cDefficient of annual streamflDw versus ditch diversiDns is 0.84. TherefDre, RDbert MDrrisDn and King CDnsDlidated diversion recDrds were used tD estimate Salt Creek flDWS during the'ten year periDd when . . . . -9- .
