During heavy snow year$, when only a <br />mininal amount of snCMrnaking would be used, Imore water will <br />be produced from the natural snow pack than ~uring dry years <br />when much snow making is required. OITerall, I snowmaking will <br />not produce significant increases in water prqauction. <br /> <br />I <br />I <br />I <br />I <br />The proponent has 22.6 cubic feet per second I (cfs) in surface <br />flow water rights (primarily in l2 irrigatio~ ditches) in the <br />West Fork and tributaries, and two conditional well water <br />rights in the alluvium of the West Fork. Tt)e Water Use Plan <br />of Augmentation (W.B. Schroeder, D.C. Hallford, and T.S. <br />Sullivan; 1984) was approved on November 26, i 1984 in District <br />Water Court, District Seven. The augmentation plan proposes <br />to change 649 acre-feet of existing lconsumptive use <br />associated with nine ditches to a range of uses including <br />domestic, commercial, irrigation, fire prot~ction, and other <br />beneficial uses. I <br />! <br />The Augmentation Plan considers the historical water <br />"depletion" associated with the nine ditches that is <br />available for use, and carefully coordinaBes diversion and <br />storage to maintain Colorado Water Conserv~tion Board (ONCB) <br />instream flow needs for the West Fork of t1-Je San Juan River. <br />The plan includes two off-channel (100 I acre feet each) <br />reservoirs (Wolf Creek Reservoirs 1 a~d 2) to store <br />consunptive use water not required to replace depletions. <br />Some alternate points of diversion are plantled for several of <br />the proponent's surface flow rights. I <br />i <br />The water for the base area will be p~ovided through a <br />central municipal water system from wells.1 Golf course and <br />pasture irrigation will be provided from di~ches. Streamflow <br />increases in the West Fork from "'.ay through September are <br />anticipated as base area water use will hot be as large as <br />historic irrigation.

About <br />l49 acres have been identified for possible coverage with <br />man-made snow which would be prOlTided th~ough a combination <br />of the structures to be augmented (storag~s, diversions, and <br />wells). The total arrount of water requirec;'l for such a system <br />is dependent on weather conditions, terr4in irregularities, <br />depth of coverage, and system efficiency.
