Up to three scenarios of future irrigation demands <br />in the basin will be imposed as follows: <br />ao Historical diversion levels of the irrigation <br />systemso <br />bo A diversion level for the irrigation systems <br />derived by limiting the historic diversions <br />to a function of the estimated historic <br />consumptive use (perhaps reflecting a 50 <br />percent ditch efficiency). <br />c. A diversion level for the irrigation systems <br />derived by limiting the historic diversions <br />to a function of the estimated historic <br />consumptive use (perhaps reflecting a 30 <br />percent ditch efficiency). <br /> <br />L <br /> <br />Estimates will be required of historic consumptive use <br />under the major irrigation rights to be modeled and a <br />pattern of return flows to the river. If previous <br />estimates of consumptive use are not available, then <br />estimates will be derived using the Blaney-Criddle <br />methodo It is anticipated that estimates of ditch <br />system crop acreages will be available from a data base <br />prepared by the State Engineer's Office. Estimates of <br />consumptive use and return flow patterns will be refined <br />through the calibration phase of Task 6c. <br /> <br />Work Product: Generated modeling input data unique to <br />determinations of Rio Grande storable flows. <br /> <br />L <br /> <br />f <br />j <br /> <br />16 <br /> <br />~ <br /> <br />Leonard Rice Consulting Waler Engineers, Inc. <br />
