<br />\ ': ," <br /> <br />j'\:,,~,,!"!' <br />oJu_.~ <br /> <br />- 11 - <br /> <br />The lack of"'lift'e"season water encourages the over application of <br />spring flows where availale. Provision of late season from storage <br /> <br />should reduce this practice. Project water supply will be dependent <br /> <br />on reduction of spring diversions. <br /> <br />The presently irrigated acreage is estimated to be 14,500 <br />acres which cause a stream depletion of 14,700 acre feet per year. <br />Precipitation during the growing season is less than 8 inches. <br />The city of Durango derives its water supply from the Florida <br />River and during years of low water supply, such as 1956, severe <br />shortages were experienced. <br />5. Animas River Basin. <br /> <br />The Animas River is the largest tributary of the San Juan <br />River. The Florida River watershed is actually a sub-basin of <br />the Animas River. The water supply of the two streams are signi- <br />ficantly different, however, because the Animas Riyer has its source <br />far north of the Florida in the high and rugged San Juan mountains. <br />It is deeply entrenched in steep walled canyons until it emerges <br />into narrow gently sloping mountain valleys nort~ of Durango. <br />Direct flow rights total 211 cfs on the main stem of the <br />Animas River and 32 cfs on Hermosa Creek. There is an ample <br />water supply to provide for these rights. The present irrigated <br />acreage is estimated to be 10,300 acres and the stream depletion <br />12,000 acre feet per year. <br />Combined with the Florida River the total irrigated acreage <br />is about 24,800 acres and the stream depletion 26,700 acre feet <br />per year. In addition, it is estimated that depletions resulting <br /> <br />from domestic uses, and reservoir evaporation losses are 2,000 <br /> <br />acre feet per acre. <br /> <br />.." -" . ,. .~., <br /> <br />, <br />, <br />,,_;1.~ <br />
