Agenda Item 9d May 24-25, 1999 Board Meeting Page 3 of5 CD >i-'>> DEPLETION BASELINE The depletion baseline has changed at least for Colorado from that identified as the 1991 Environmental Baseline in the Animas-La Plata Biological Opinion, Based on recent CRDSS model runs, Colorado provided the following infonnation update for inclusion in the hydrologic modeling done for the SJRIP. Comparisons of the depletion estimates as the currently stand are shown on the attached table. The intent is have the applicant identifY the water rights and any historic diversion amounts associated with those rights as part of the initial application in the Section 7 process, The Service would then work with each state to verifY the water rights and historic diversions and arrive at a consensus of how much of the project rights are historic and covered by the program and how much would be considered new water development and charged against the 122,000 AF of allowable new depletions under the program, Irril!ated Acres Our baseline irrigated acres are based on the 1993 survey of irrigated acres done by the State of Colorado and the U .S, Bureau of Reclamation. The irrigated acres account for all potentially irrigated acres including aeres that were identified as fallow in 1993, The values, reported by water district are as follows: Water District 1993 Irrigated 1993 Fallow 1986 Settlement Total Basel ine Acres Acres Acres Acres 29 12,777 584 1,317 14,678 77 2,738 89 2,827 78 & 46 6,547 1,240 1,196 8,983 31 46,555 798 47,353 30 32,489 654 815 33,958 33 20,090 2,391 22,481 34 12.442 61 8.400 20,903 T olal Acres 133,638 5,817 11,728 151,183 Please note that irrigated acres for Water District 32 are not included in these values because the water supply to irrigate the acres in Water District 32 is derived from imports to the McElmo Creek Basin from the Dolores River, Please note that the \986 Settlement Acres do not include any Dolores Project or Animas-La Plata Project acres, Dolores Project acres are in Water District 32 and covered under the existing section 7 consultation for the Dolores Project.
