With heade;o.te diversions averag- <br /> <br />ing 38,324 A.F. per year (period 1927-1g40),and deliveries to the reser- <br /> <br /> <br />voir averaging 31,460 A.F. per year (during the same period), the overall <br /> <br />conveyance losses alonG the A.lT.C. averaged 6,8641\.1'. annually, or 17.%. <br /> <br />of the heade;ate diversions. <br /> <br />Segree;ations of the A.V.C. conveyance losses. as between the <br /> <br />qu~tities consumed and returned, has been accomplished by calculating <br /> <br />'. <br /> <br />the quantities consumed.
