November through April, average daily demand is about 1.1 mgd (102 acre-feet/month) <br />and during the months of May through October daily demand averages about 1.4 mgd <br />(131.0 acre-feet/month). The District's general manager indicates that the peak daily <br />demand is approximately 2.2 mgd. <br />3.5. WATER RIGHTS AND EXISTING YIELD <br />The decreed water rights for the District and a summary of their approximate seasonal <br />and annual yield are listed below in Table No. 2. Yield information is based on <br />hydrological analyses of Evans Gulch basin, historic diversion records, and discussions <br />with the District General Manager. <br />TABLE 2 <br />SUMMARY OF THE DISTRICT'S WATER <br />RIGHTS AND THEIR APPROXIMATE <br />AVERAGE YEAR YIELD <br />Approximate Approximate <br />Actual May- Actual Nov- Approximate <br />Oct Avg Apr Avg Total Annual <br />Decreed Monthly Yield Monthly Yield Yield <br />Water Ri ht Yield ac-ft ac-ft ac-ft <br />Evans Gulch - Direct Flow 8.65 cfs <br />Evans Gulch — Stora e 191.3 ac-ft 179 7g,5� 1,540 <br />Elkhorn Shaft (lowa Ditch & Blow 1.46 cfs <br />Ditch <br />lowa Gulch - lowa Ditchl 11.737 cfs 43 24 450 <br />Em ire Gulch - Blow Ditch 2 cfs 0 41 245 <br />Arkansas Wells (1.5 cfs - lowa 1.5 cfs 23.4 23.4 280 <br />Ditch, 1.5 cfs — Stevens & Leiter <br />Canterbury Tunnel (1.5 cfs - 1.5 cfs 83.0 83.0 1,000 <br />Stevens & Leiter <br />' The May through October average yield from Evans Gulch is currently limited by the maximum <br />treatment capacity (2 mgd) at the District's water treatment plant. <br />Z The facilities are not currently operational due to the condition of the structures <br />and treatment requirements. Yields, therefore, are available under the District's water <br />rights but not physically available to their water supply. <br />3.6. COMPARISON OF WATER DEMAND AND AVAILABILITY <br />Table No. 3 provides a comparison of the District's varying demands relative to available <br />supply. It also provides the comparison relative to future demands. Present yields and <br />demands are based on hydrological analyses of the Evans Gulch basin, historic <br />_! W. W.
