Show -8- thousand acres are well above the flood levels, and I believe that the difficulty and expense of protecting the entire tract from danger of overflow would be small, on an acreage basis. As a matter of fact, the main branch canals, for the irrigation of this tract, would run parallel with the river, and the banks of these canals would, in most cases, form the only levees required. Water supply The water for the irrigation of these lands must necessarily come from the Colorado River. There is no other source of supply I have not yet undertaken to measure the flow of the river, since these measurements, to be of value, must be very complete and correspondingly expensive. The data that I can obtain from the U. S. Govt. Reports is very meagre. I find the following three measurements made by the Wheeler Survey: Water Flow, surface cu. ft. per below Locality Date second. high water Stone's ferry, Nevada, Aug. 12,1875 18410 17 feet Fort Mohave, Cal.

It is important, that a very complete guaging of the river be made. Daily measurements of the flow should |
