<br />. <br /> <br />e <br /> <br />. <br /> <br />STORABLE FLOWS <br />Direct Flow Water Rights <br />As mentioned above, the CWCB estimates that the historical average depletions of the Simonton <br />Ditch were 276 acre-feet/year. Normally, this amount of water could replace most all ofthe annual <br />evaporation from the present Conservation Pool of 1,989 acre-feet. At that level, the surface area is <br />approximately 107 acres. The Simonton right, if successfully transferred for this purpose, would <br />receive a fuU water supply in all years of this study. <br /> <br />Storage Rights <br />The storable water available from the CWCB storage rights of 3,989 acre.feet depends on the excess <br />water available in Bear Creek. The Model quantifies the water available to water rights junior to <br />Priority No. 19 on a daily basis. Most of these junior water rights belong to the Denver Water <br />Department although the junior water rights in the Ward Canal could divert a portion of the excess <br />water. Denver Conduit IS, a 72-inch diameter pipe, conveys water from the Harriman Ditch head gate <br />to Marston Lake. There is sufficient capacity for Denver's junior water rights to divert about 150 cfs. <br />Although it may be conservative to subtract the fuU 150 cfs at aU times from the excess water available <br />in Bear Creek by the Model, this was done to compute the storable flows available to the CWCB's <br />storage water rights during times of no demand on the South Platte River. <br /> <br />Since the Model excludes 1949, a very wet year, the storable flows were estimated by subtracting a fuU. <br />230 cfs from the measured flows at the Morrison Gage on Bear Creek at all times. There would be <br />a full supply available to CWCB in 1949. <br /> <br />The supporting calculations for the storable flows can be found in Appendix C, which consists of <br />computer sheets for months when excess water would have been available in Bear Creek for the <br />CWCB storage rights. The explanation of the column headings of the computer printouts can be <br />found in Table A. <br /> <br />The storable water in Bear Creek, on a monthly basis, is summarized in Table B. Also shown are the <br />amounts available to the CWCB. The CWCB had a fuU supply of 3,989 acre-feet during both 1949 <br />and 1957. A total of 2,540 acre-feet could have been stored during 1952 and no storable water was <br />available during the remaining years of 1950,1951,1953,1954,1955 and 1956. <br /> <br />Note that no water was stored during the winter months. During most "wet" years, the daily flow <br />rarely exceeds 40 cfs, during which time the City of Denver can be expected to divert the entire <br />amount from November 1 through March 31. NormaUy, there is also a South Platte River call most <br />of the time during this period. <br /> <br />1953 <br /> <br />S9..Q26.00W <br /> <br />7 <br />
