UVWUA storage at Taylor Park was not <br /> <br />limited by an amount of exchange water on account at Blue Mesa, UVWUA <br /> <br />storage at Taylor Park was carried over from year to year, and all storage <br /> <br />releases to meet irrigation demands at the Gunnison Tunnel were charged <br /> <br />against Taylor Park. The USBR targets for Blue Mesa storage were <br /> <br />consequently adjusted by subtracting the average amount of UVWUA storage <br /> <br />water on account at Blue Mesa (Table 4) from the USBR targets. The <br /> <br />resulting targets shoWYI in Table 5 were used to simulate Blue Mesa <br /> <br />operations in the model. <br /> <br />TABLE 5: Adjusted Blue Mesa Storage Target (1000 acre feet) <br /> <br />Oct <br />702 <br /> <br />641 <br /> <br />Dec <br />576 <br /> <br />Jan <br />483 <br /> <br />Feb <br />409 <br /> <br />Mar <br /> <br />344 <br /> <br />Apr <br />468 <br /> <br />Mav <br />53S <br /> <br />Jun <br /> <br />Jul <br /> <br />AUQ <br />798 <br /> <br />~p <br /> <br />Nov <br /> <br />74S <br /> <br />824 <br /> <br />7~ <br /> <br />This adjustment allows Blue Mesa and Taylor Park exchange operations <br /> <br />to be eKamined independently and simplifies the model. The operation of <br /> <br />the exchange with the unadjusted Blue Mesa targets is illustrated below. <br /> <br />H. Evaporation <br /> <br />Reservoir evaporation is determined by the model at the end of each <br /> <br />month and subtracted from ending reservoir contents. This adjustment for <br /> <br />evaporation often leaves reservoir contents slightly below targets. The <br /> <br />WBLA, Inc. 1909 Broadway, #3, Boulder, Colorado 80302 <br /> <br />
