Present Use of Water Supply. <br />An evaluation of the present irrigated acreage and depletions <br />is given in the following paragraphs. Depletions include water <br /> <br />consumed by reservoir evaporation and consumed on areas incidental <br /> <br />to irrigated areas such as seeped ground. In general, this <br />tabulation is by tributaries of the San Juan River which constitute <br />separate basins. Data on irrigated acreages and depletion rates <br />are for the most part from the Report of the Engineering Advisory <br />Committee of the Upper Colorado River Compact Commission. These <br />data were modified where records of more recent irrigated acreages <br /> <br />are available. To these acreages are applied depletion rates <br />derived from inflow-outflow studies, from the Blaney-Criddle <br />method of determining consumptive use, or from estimates of the <br />Engineering Department of the Colorado Water Conservation Board. <br />
