Show -15- At the headgates, the bottom of the canal will be at an elevation of 10.2 feet below mean low water in the river for the month of March; no Dam hence an adequate volume of water will be assured without a dam. Proposed dimensions Above ei Rio From the Potholes to El Rio, a distance of 13 miles, the canal has been finally located and estimates of yardage prepared on the following basis, which I recommend for adoption, Grade, 0.35 feet in 5000 ft. Cross-section Bottom width, 116 feet. Top 158 " Depth, 14 " Top width of lower levee, 10 " " upper " , 6 " Outer slope of lower levee, 2:1 All other slopes, 1.5:1 Maximum depth of water, 11 feet. Carrying capacity, at 11 feet depth, 3500 cubic feet per second. " 10 " " . 3000 " " " " . At El Rio, it is proposed to turn back into the river a large portion of the water, and create there a water power for purposes which will be hereafter explained. ei Rio From El Rio to the Salton Basin, such grades and dimensions have been given as will allow the delivery of 2000 cubic feet per second to the lands. These dimensions vary with the character of the work encountered and detail data of all changes will be shown on the profile accompanying this report; but throughout the greater part of its length below El Rio the canal will have a fall of 1 foot in 5000, a bottom width of 110 feet, a depth of |
