reservoir never fills and is always below its decreed capacity (the maximum he has observed is <br />58,000 acre-feet). The Commissioner estimated that approximately 20,000 acre-feet is stored in <br />Sanchez Reservoir each year. Travel time between Sanchez Reservoir and downstream diversion <br />points is between 6 and 10 hours. The current president of the Sanchez Ditch and Reservoir <br />Company is Jerry Lorenz. <br />Storage in Sanchez Reservoir can occur by way of diversions directly from Culebra Creek (via <br />the Culebra-Sanchez Canal) or from water from Quates, Jarosa ,Torcido, Vallejos, and San <br />Francisco creeks. Water from Vallejos and San Francisco creeks can be dumped into the <br />Culebra-Sanchez Canal for delivery to the reservoir. Water from Quates, Jarosa and Torcido <br />creeks occasionally drain directly into the reservoir. The Commissioner estimated that 98 percent <br />of water stored in Sanchez is from Culebra Creek. Sanchez Reservoir serves two major canals: <br />the Culebra-Cerritos, and the Culebra Eastdale. The Culebra-Cerritos Canal prefers to run <br />between 3 and 15 cfs through their canal system, and reservoir water is used to help sustain this <br />diversion rate. The Culebra-Eastdale Canal prefers to run approximately 8 cfs through their <br />system. <br />Eastdale No.l and No.2 reservoirs are owned by Dean Swift. These reservoirs are off-channel <br />storage vessels built in the early 1900s that are supplied primarily by way of diversions through <br />the Culebra-Eastdale Ditch. Storage from delivery of Culebra Creek water typically occurs <br />during the winter months. Water can also be delivered into Eastdale No. 1 via diversions through <br />the Cerro Canal which diverts water from Costilla Creek (a minimum delivery of 1,000 of from <br />Costilla Creek to the reservoir is specified in the Costilla Creek Compact). The reservoirs lie to <br />the north of Costilla Creek and about 4 miles due north from the Town of Jarosa. Eastdale No. l <br />and No.2 have decreed capacities of 3,468 acre-feet and 3,041 acre-feet, respectively. The two <br />reservoirs are effectively managed as one storage facility, with the No.2 reservoir being used only <br />when the No. l reservoir is full or requires maintenance. <br />In addition, there are numerous decreed storage rights for smaller reservoirs, lakes and stock <br />ponds in the District. The District Commissioner does not actively administer these storage <br />facilities. <br />As with direct flow diversions, the surface water model being developed for the RGDSS will <br />consider certain storage structures as key. The District Commissioners confirmed that Sanchez, <br />Eastdale No.l and Eastdale No.2 are the principal storage structures in the District and the only <br />ones that significantly effect water rights administration. Although numerous small stock ponds <br />exist in the District with decreed water rights, these ponds fill each year with natural local runoff <br />from precipitation. <br />The role of the Water Commissioner with respect to operations reservoirs in the District is <br />generally limited to 1) ensuring inflows are passed when storage not approved, 2) approving <br />storage under different water rights; and 3) ensuring reservoir deliveries at appropriate headgates. <br />Trans-Mountain Diversions <br />There are no trans-mountain delivery or release points within District 24. <br />Day to Day Water Rights Administration <br />Water rights administration occurs by way of frequent and detailed communication between the <br />District 24 Commissioner, the Division 3 Engineer (Steve Vandiver) and his staff, the Water <br />C:Acdss\D24 Mem.doc District 24 Interview July 2, 1999 -Page 4 of 7 <br />
