Results <br />Figure 1 shows the 6-year average annual consumptive use for the different non-evapotranspiration <br />categories. The total annual consumptive use for the non-evapotranspiration categories (excluding <br />mineral resources and export) is 25,780 acre-ft, where approximately 50 percent is evaporation losses <br />from reservoirs. Figure 2 shows the 6-year average annual consumptive use distribution by subarea. <br />Gunnison2 has the highest consumptive use (approximately 36 percent of the total consumptive use), <br />Mesa5 has the highest consumptive use for livestock and export categories, Montrose6 has the highest <br />consumptive use for stock pond and municipal categories, and Gunnison2 has the highest consumptive <br />use for reservoir category. The details of the results of the calculations are shown in Section 5.0. <br />3.0 CONCLUSIONS AND RECOMMENDATIONS <br />The CU model is implemented using the Gunnison River basin database. Consumptive use estimates for <br />the livestock, stock pond, reservoir, and municipal categories are obtained for each subarea that <br />comprises the Gunnison River basin. No data are identified for the mineral resources and export <br />categories. <br />The 6-year average annual consumptive use for non-evapotranspiration categories is 18,970 acre-ft, the <br />greater part of which is evaporation from reservoirs. <br />4.0 REFERENCES <br />Blaney, H.F.
