No releases were allowed to exceed the maximum practical <br />outlet release of 113,000 cubic feet per second. <br /> <br />c. Values of 0 to 40,000 cubic feet per secCDd in tables 1 <br />through 3, which indicate the releases necessary during January, February <br />and March, are based upon a release of 40,000 cubic feet per second <br />during April, May, June and July. <br /> <br />d. Values in tables 1 through 3 do not exceed 40,000 cubic <br />feet per second unless releases of 75,000 cubic feet per second would <br />be necessary during all four succeeding DIOnths. <br /> <br />e. Values in tables 1 through 3 of 75,000 cubic feet per <br />second or greater are average releases during the periods 1 January to <br />1 August, 1 February to 1 August, and 1 March to 1 August, respectively. <br /> <br />f. Values in tables 4 through 6 are average releases during <br />the periods 1 April to 1 August, 1 May to 1 August, and 1 June to 1 <br />August, respectively. <br /> <br />g. NOrllBlly the releases specified in table 6 will be appli- <br />cable through the month of July, with the objective of having the res- <br />ervoir vater surface at elevation 1,219.61 feet (1,500,000 acre-feet <br />below elevation 1,229.0 feet) CD 1 August. Revisions to these m1n1_ <br />releases -.y be made during July if Justified by a forecast of the re- <br />maining runoff and comparison with empty reservoir space available. <br /> <br />26. When the releases given in tables 4 through 6 of Appendix A <br />are between 20,000 and 40,000 cubic feet per second, it will be pends- <br />sible to release less than the indicated amounts for a part of the <br />period, provided the average releases for the entire period will equal <br />the releases given in the table without flows exceeding 40,000 cubic <br />feet per second at the gaging station, Colorado River below Davis Dam. <br />This method of operation delays releases in excess of powerplant capacity <br />until DIOre accurate succeeding forecasts are available. <br /> <br />10 <br />
