<br />""1' <br />" <br />00 <br />C\J <br /> <br />There is shown graphically on Plote 4 the relation between <br /> <br />the last Gay of storage and the ~ount storable in Haystack Roser- <br /> <br />voir, under several sets of ~JndititJns: <br /> <br />Curve 1 - All water available above Haystack Reservoir and its <br />feeder canals to be stored until date when diversions <br />are reduced; <br /> <br />Curve 2 - Diversion demand of Table 4 to be applied to water avail- <br />able below Haystack Reservoir, qnd deficiency supplied <br />from storable water until it all passes into direct use; <br /> <br />Curve 3 - Continuation of past rates of diverSion, with deficiencies <br />supplied as in Curve 2 until stcrable water has all passed <br />into direct use. <br /> <br />Curve 1 is not based on any definite assUIcpti on as to <br /> <br />what diversion practice has been or should be before the uate when <br /> <br />diversion s were cut, ane since it eepends solely on that date it <br /> <br />ignores possible ceficiencies in stream flow before that ('ate, and <br /> <br />might in some years be considerably in error. Curves 2 and 3, which <br /> <br />take account of such deficiencies in years of recore, indicate what <br /> <br />restriction of use may be necessary to assure storing 7,000 acre- <br /> <br />feet in Haystack Reservoir. <br /> <br />Curve 2 results from the application of the ideal demand <br /> <br />of Table 4 to the flow for the perioe before the date of last <br /> <br />storage, and since it practically coincides with Curve 1, shows <br /> <br />that spring diversions must be materially reduced in drier years <br /> <br />to fill the Haystack Reservdr. This is confirmed by Curve 3 <br /> <br />,n <br /> <br />~ <br />'. <br /> <br />. <br />, <br />
