Based on recent CRDSS model runs, Colorado provided the following <br />information update for inclusion in the hydrologic modeling done for the SOOP. <br />Comparisons of the depletion estimates as the currently stand are shown on the <br />attached table. <br /> <br />The intent is have the applicant identify the water rights and any historic <br />diversion amounts associated with those rights as part of the initial application in <br />the Section 7 process. The Service would then work with each state to verify the <br />water rights and historic diversions and arrive at a consensus of how much of the <br />project rights are historic and covered by the program and how much would be <br />considered new water development and charged against the 122,000 AF of <br />allowable new depletions under the program. <br /> <br />Irril!ated Acres <br /> <br />Our baseline irrigated acres are based on the 1993 survey of irrigated acres <br />done by the State of Colorado and the U,S, Bureau of Reclamation, The irrigated <br />acres account for all potentially irrigated acres including acres that were identified <br />as fallow in 1993. The values, reported by water district are as follows: <br /> <br />. <br /> <br />Water District 1993 Irrigated 1993 Fallow 1986 Settlement Total Baseline <br /> Acres Acres Acres Acres <br />29 12,777 584 1,317 14,678 <br />77 2,738 89 2,827 <br />78 & 46 6,547 1,240 1,196 8,983 <br />31 46,555 798 47,353 <br />30 32,489 654 815 33,958 <br />33 20,090 2,391 22,481 <br />34 12.442 61 8.400 20.903 <br />Total Acres 133,638 5,817 11,728 151,183 <br /> <br />Please note that irrigated acres for Water District 32 are not included in <br />these values because the water supply to irrigate the acres in Water District 32 is <br />derived from imports to the McElmo Creek Basin from the Dolores River. Please <br />note that the 1986 Settlement Acres do not include any Dolores Project or <br />Animas-La Plata Project acres, Dolores Project acres are in Water District 32 and <br />covered under the existing section 7 consultation for the Dolores Project. The <br />Animas-La Plata Project is addressed separately below, <br /> <br />M&I Consumntive Uses <br /> <br />Colorado's M&I consumptive uses are identified as follows in our current <br />version of STATE MOD: <br />
