Maximum annual capacity of the Cheyenne Stage UII system <br />(22,656 AF/year) is dictated by a one-fill limitation on Hog Park Reservoir. Although the City of <br />Cheyenne has no immediate plans to enlarge this system, under current growth estimates, it should <br />reach full capacity in the 2040-2050 timefrarne (States West Water Resources 2000). <br /> <br />The difference between current and future agricultural depletions (10,546 AF/year) is attributable <br />to eight small projects whose individual annual depletions range from 100 to 2,656 AF (Table 13). <br /> <br />Table 13.

These new depletions are attributed to a threefold <br />expansion of constructed wetlands (1,000 AF) by the Little Snake River Conservation District, and <br />the Little Snake River Basin Small Reservoirs Project (614 AF), 10 small impoundments with a <br />combined surface area of245 acres that the District proposes to build for stock watering, rangeland <br />improvement, and wildlife enhancemenL Two other impoundments will be constructed under <br />existing funding, with a combined surface area of 19.5 acres and combined depletions of <br />49 AF/year, assuming a net evaporation of 30 inches/year, These two reservoirs were included <br />under existing depletions (States West Water Resources 2000). <br /> <br />Combining depletions from the Little Snake River in Colorado and Wyoming results in basin-wide <br />depletions as shown in Table 14, In this summary, Colorado Water District 54 depletions are <br />included with Wyoming depletions above Baggs, while WD 55 depletions are included with <br />Wyoming depletions below Baggs. Future depletions in Wyoming that were not attributed to a <br />specific geographic region (i.e., 7,816 AF total depletions for evaporation, miscellaneous stock <br />reservoirs, and industrial uses) were prorated in the same proportion as regional depletions by <br />irrigation, assigning 5,471 AF (70 %) to the region above Baggs and 2,345 AF (30 %) to the region <br />below Baggs. <br /> <br />~ <br />!3 <br />'; <br /> <br />Management Plan for Endangered Fishes in the Yampa River Basin <br /> <br />27 <br />
