The complete analysis made of these absolute rights is shown in <br />Appendix Section E. The above diversion rates result in an annual <br />application of approximately eight acre-feet per acre of irrigated land for <br />the reach of the river studied. <br /> <br />The monthly ciiversion for the senior ,~bsolute rights was combined with <br />tributary inflow and return flows to determine the minimum amount of water <br />which must be provided at the confluence of the North and South Forks. The <br />following tabulation shows the monthly volumes of water that must be <br />available to satisfy senior absolute rights. <br /> <br />Month <br /> <br />Total <br /> <br />Senior Conditional Water Rights <br />The most significant conditional water rights senior to the YJWCD rights are <br />those on the South Fork associated with the Stillwater Project. These <br />rights consist of 370 cfs of direct flow and 12,550 acre-feet of storage. <br />Of the direct flow right, 300 cfs is an on-channel, nonconsumptive right <br />related to hydropower. If developed and put into use, the power right would <br />not diminish the quantity of flow downstream and therefore would be <br />available for use by absolute water rights. The remaining 70 cfs of the <br />Stillwater ri~lht is a direct flow consumptive right. For the operation <br />studies, it wc.s assumed that this 70-cfs right would not be available to <br />help meet the downstream senior absolute water demand. <br /> <br />V-4 <br />
