-2- being the average over the period of 1899 to 1920, both included, a period of 22 years. However, during the period of 1905 to 1920, both years included, Yuma shows an average of 18,244,444 acre feet and Laguna 17,218,000 acre feet per annum. Adding to the amount disclosed at Yuma the amount diverted and used above, including that from the streams in Arizona, would make the production of the basin between 22,000,000 and 24,000,000 acre feet per annum, reckoned from that station. Further calculations and deductions will disclose practically the same amount of water passing Lee's Ferry as Laguna, each approximately 1,000,000 acre feet less than at Yuma. Further, there is an inflow between Lee's Ferry and the measuring station at Topock, which would be practically the same as at Boulder canyon, of 2,500,000 acre feet; the principal streams which must furnish this are Little Colorado, Kanab creek, Cataract, Diamond creek and the Virgin river. This amount of water is lost by evaporation, percolation or seepage and diversion before it reaches Laguna. That amount, however, is present at or near the Boulder canyon, for use from there if the river can be stabilized and controlled so as to reduce the waste to a minimum.
