The maximum flow of the Colorado River Is from 70,000 to 110,000 cubic feet per second and occurs during the months of May, June, and July, the time when water Is most needed for Irrigation. The maximum capacity of the main canal of the Palo Verde Mutual Water Coapany Is about 700 cubic feet per second; and, as the greatest demand for water wo_Lld occur during the months when the river reaches Its maximum flow, there would be diverted less than 1$ of the entire discharge of the river. The records obtained from the gauging station at Yuma, Arizona, Indicate that the minimum flow of the river occurs during the months of October, :Tov ember, December, and January, and Is approximately 5,000 cuolc feet per second. During this time, practically no water would be required for Irrigation purpose? in the Palo Verie Valley. The ground water level or water table in the Palo Vercie Valley Is within ten to twenty feet from the surface and the underground drainage is lntr the Colorado River; therefore a large percentage of the water turned on the land for purposes of irrigation eventually finds Its way bacKto t'ne Colorauo hirer through underground drainage.
