<br />.....'." <br /> <br />-:) <br /> <br />-\ <br /> <br />PROPOSED CATLIN TRANSFER PLAN <br />------------- - --- <br /> <br />N---- <br />o <br />.:-::> <br />,.j;:o, <br /> <br />COLORADO WATER CONSERVATION BOARD <br /> <br />October 16, 1974 <br /> <br />1. The State of Colorado has purchased 2,097.58 Catlin shares <br />of a total of 18,660 shares or 11.24 percent of the total. <br /> <br />2. The catlin Canal has two decrees: <br /> <br />248 cfs with a priority date of 12/3/1884 <br />97 cfs with a priority date of 11/14/1887 <br /> <br />3. Historic headgate diversions of the Catlin Canal are shown <br />in table 1. Values shown include the water released from <br />Mt. Pisgah Reservoir and purchased from other sources. <br /> <br />4. Those who sold their Catlin shares were contacted, and it <br />was determined that 2,336 acres were irrigated with the <br />state's shares and that 2,206 acres were irrigated at least <br />once each winter in February or March. <br /> <br />A. Irrigation season consumptive use from 2,336 <br />acres is shown in table 2 and average 4,533 <br />acre-feet annually or about 1.94 acre-feet <br />per acre. Consumptive use was computed using <br />a modified Jensen-Haise method. <br /> <br />B. winter consumptive use from 2,206 acres was <br />estimated to be 263 acre-feet annually and <br />was estimated by applying winter lake evapora- <br />tion to the irrigated area for a two-week <br />period. <br /> <br />5. The return flow used in the transfer plan is 20 percent. <br />This is the percent recharge determined for the Catlin's <br />Arkansas River reach by the U.S.G.S. with their digital <br />model. <br /> <br />6. Conveyance losses were assumed to be 0.07 percent per mile, <br />which is the rate the state engineer presently charges on <br />deliveries of storage water. <br />
