Using this method, Table No.1 <br />attached hereto shows the present level of losses at 317,000 acre-feet <br />per year. This is not a measured loss per se, but reaults from a water <br />budget analysis which takes into account records of releases from <br />Lake Mead, inflow from tributaries which are measured, reservoir storage <br /> <br />changes, and diversions from and returns to the river including diversions <br /> <br /> <br />by miscellaneous users pumping from the underground system of the river. <br /> <br /> <br />The balancing figure then represents the net loas. <br /> <br />Estimates of fUture losses have been made based on the present loss level <br /> <br />adjusted by (1) future Bill Williams River inflow estimated at 65,000 acre-feet, <br />(2) an assumed decreased rate of consumptive use per acre on Colorado River <br />Indian Reservation amounting to a total of 56,000 acre-feet after full <br />development, (3) assigning the 80,000 acre-feet of net gain, Imperial Dam <br />to Northerly Boundary, to wuneasured return flow from irrigation operations, <br />(4) an assumed change in estimated depletions by miscellaneous users in <br />other areas of 42,000 acre-feet, (5) excess deliveries to Mexico estimated <br />at 85,000 acre-feet, and (6) aalvages estimated to be accomplished in the <br />fUture by the Bureau of Reclamation's salvage program, i.e., 100,000 acre-feet <br />from a phreatophyte control program and 170,000 acre-feet from the river <br />management and channelization program. Based on the foregoing adjustments, <br /> <br />6 <br />
