4.3 Reservoirs <br />Reservoirs are described in the Yampa Model by five input files: <br />4.3.1 Reservoir Station File <br />4.3.2 Net Evaporation File <br />4.3.3 EOM Content File <br />4.3.4 Reservoir Target File <br />4.3.5 Reservoir Right File <br />4.3.1 Reservoir Station File - yampaT.res <br />The yampaT.res file describes the physical properties of each reservoir simulated in the Yampa River <br />basin. Table 4.3.1a summarizes the key data associated with each of the reservoirs modeled. <br />Appendix C, Section 10 discusses the specific operations of each explicitly modeled reservoir. <br />Appendix D.11 describes the aggregated reservoirs. <br />TABLE 4.3.1A <br />Reservoir Summary <br /># <br />ID # <br />Name <br />Location <br />Capacity <br />acre -feet <br /># <br />Owners <br />1 <br />583540 <br />STILLWATER RES NO 1 <br />YAMP STILLWATER RES RES <br />6392. <br />8 <br />2 <br />584240 <br />YAMCOLA RES <br />YAMP YAMCOLA RES RES <br />9096. <br />12 <br />3 <br />583500 <br />ALLEN BASIN RES <br />MIDD ALLEN BASIN RES RES <br />2250. <br />3 <br />4 <br />584213 <br />STAGECOACH RESERVOIR <br />YAMP BEAR RES WESSEL RES <br />33275. <br />5 <br />5 <br />583631 <br />LAKE CATAMOUNT <br />YAMP _LAKE CATAMOUNT <br />RES <br />7422. <br />1 <br />6 <br />583508 <br />FISH CREEK RES <br />MIDD FISH CREEK RES RES <br />4042. <br />1 <br />7 <br />583787 <br />STEAMBOAT LAKE <br />WILL UPPER WILLOW CR RES <br />26364. <br />2 <br />8 <br />583521 <br />LESTER CR RES <br />LEST LESTER CR RES RES <br />5657. <br />1 <br />9 <br />443902 <br />ELKHEAD RESERVOIR <br />ELKH ELK HEAD RESERV RES <br />13699. <br />3 <br />10 <br />ARY 001 <br />ARY 001 <br />ARY 001 Yam aRbelCra RES <br />23206. <br />1 <br />11 <br />ARY 002 <br />ARY 002 Yam a eerlod e <br />ARY 002 Yam aR Deerl RES <br />9122. <br />1 <br />12 <br />ARY 003 <br />ARY 003 LSnakeRnrLily <br />ARY 003 LSnakeRnrLil RES <br />1494. <br />1 <br />13 <br />ASY 001 <br />ASY 001 YampaRbelCraig <br />ASY 001 Yam aRbelCm RES <br />8344. <br />1 <br />14 <br />I ASY 002 <br />ASY 002 Yam aR Deerlod e <br />ASY 002 Yam aR Deerl RES <br />4441. <br />1 <br />15 <br />1 ASY 003 <br />1 ASY 003 LSnakeRnrLil <br />1 ASY 003 LSnakeRnrLil RES <br />3173. <br />1 <br />Nine reservoirs were modeled explicitly in the Yampa Model; these included eight reservoirs that <br />have a capacity greater than the cutoff value of 4,000 acre -feet and one reservoir with a capacity less <br />than the cutoff value. Of the smaller reservoirs, Fish Creek Reservoir was included because it is the <br />major municipal storage facility for the city of Steamboat Springs and the Mt. Werner Water & <br />Sanitation District and because it is presently being enlarged to a total capacity of approximately <br />4,042 acre -feet. The enlargement was completed in the fall of 1995. Although Fish Creek Reservoir <br />is modeled at its current, enlarged capacity, its storage target for the study period was set to 1,842 <br />acre -feet, which is the pre - enlargement storage volume. Allen Basin Reservoir was included because <br />it was identified as a key storage source for many of the direct flow water rights in the upper reaches <br />of Hunt Creek and because it is directly related to a large transbasin feeder ditch, the Allen Basin <br />Supply Ditch. <br />Six aggregated reservoirs were added to the model under Phase IIIa to represent all of the absolute <br />decreed storage (ARY 001, ARY 002, and ARY 003) and all of the stockponds (ASY 001, <br />Reservoirs 4 -11 <br />
