<br /> <br />O~CDv2 <br />. <br /> <br />. <br /> <br /> <br />. <br /> <br />- <br /> <br />adjusted for storage and water stored by exchange <br /> <br /> <br />after 1976. PRWCD records and the USGS publishes <br /> <br /> <br />storage data. April 1 snow water equivalent, SPb, <br /> <br /> <br />is obtained from the USDA Soil Conservation <br /> <br /> <br />Service. Qtr and Van Bremer Arroyo flows, Ovb are <br /> <br />measured by the State Engineer's office. <br /> <br />3. Compute measured and predicted ten year sums of <br />purgatoire River flow, at Thatcher, Em and I:p , <br />respectively. Equation A is used in Ep after <br />1977 . <br /> <br />_')'1 <br /> <br />4. Compute difference between sums, I:m-I:p . <br /> <br />5. Underdel iveries, Em-Ep < 0, are to be made up from <br />storage or project operations. <br /> <br />6. Adjustments in Van Bremer Arroyo flow, Qvb, will be <br />made by the State Engineer if significant base <br />flow occurs due to changes in Model land irrigation <br />resulting from the project and current <br />construction. <br /> <br />7. Equation A is recommended for use as long as Qtr, <br />SPb and Qvb (after adjustment noted in Step 6, <br />above) show no long term trends. The State <br />Engineer will evaluate trends and make adjustments <br />as necessary. <br /> <br />-25- <br />
