<br />M::<lSl <br />t" v _'.~ ....... <br /> <br />Draft: April 21, 1994 <br /> <br />etc., assumptions applied in depletion development. They <br />would like to use these rates for the next Beta test and <br />final model releases. <br /> <br />USBR Denver Office personnel have provided depletion <br />rates with incidental use and shortage adjustments <br />removed (See Table ~). Plots of annual consumptive use <br />rates ('52-'90;adjustments removed) for the Upper <br />Uncompahgre, Lower Uncompahgre, Lower Gunnison, and Smith <br />Fork/North Fork areas are shown on Figures 5-8. <br /> <br />During the first beta testing period, one of the testers <br />questioned the apparent upward trend in Lower Gunnison <br />depletion rates (see Figure !). This trend is not <br />apparent in the "adjustments removed" rates (Figure ~). <br /> <br />A drop appears in both adjusted and "adjustments removed" <br />rates for the Upper Uncompahgre area (Figure~, Figure~) <br />beginning in 1981. <br /> <br />Documentation for the development of irrigated <br />agriculture consumptive use as provided by the Denver <br />Office (USBR) is included in Section H of supporting <br />materials provided prior to March 18 meeting. <br /> <br />Review of documentation shows that consumptive use <br />estimates for the 1952-1990 period were developed as part <br />of five efforts: <br /> <br />1952 -1974: CRSS <br /> <br />1975 - 1985: 1971-1975 CU&L report <br />1976-1980 CU&L report <br />1981-1985 CU&L report <br /> <br />1986 - 1990: <br /> <br />methods as outlined in Methods Manual and <br />Plan of Studv for the Colorado River <br />Svstem, Consumptive Uses and Losses <br />Report; 1985-90 <br /> <br />The drop in Upper Uncompahgre consumptive use rates <br />observed in 1981 may be due all or in part to the change <br />in climate station data used in computations from <br />Montrose and Ouray to Ridgway in 1981. <br /> <br />Options: <br /> <br />1. ) Apply weather station and cropping patterns used in <br />computing consumptive use rates in 1981-1985 CU&L report for <br /> <br />11 <br />
