Show IRRIGATION WATER L UTAH MUST : 'jrriirntion farmers of Utah must lid measures to conserve their liiT supply and prevent water ( W'4c, .laaies K. Barker, Utah "tat'" 'extension irrigation specialist, special-ist, warns. ..-thousands of acres of land in (1)t, s(nte He barren for lack of jrripstion while tons of water are "oing to waste," he said. " One way in which considerable water goes to waste is through ,,'e'nige in irrigation canals. On j recent irrigation tour in Cache valley, sponsored by the county extension service office, it was found that more than 70','r of the witer wns 'ost 1,1 a three-mile stretch of one irrigation canal, jlr. Barker reported. This canal, belonging to the Richmond Irrigation Co., was los-inC los-inC l-1" cubic feet of water per second, out of a total of 2.22 cubic feet per second, or more than 52, the first one-half mile distance, he said. "It would be well for other irrigation canal owoiers throughout the state to determine how much water they are losing through seepage." Sandy loam mixed with from five to 10 bentonite is probably the most satisfactory material for lining canals to prevent seepage, according to results achieved by a soil conservation service irrigation irriga-tion research laboratory at the mouth of Logan canyon. This laboratory, with Dr. C. W. Laurit-zen Laurit-zen in charge, was visited as part of the irrigation tour. The sandy loam-bentonite mixture mix-ture will probably have to be protected pro-tected with a layer of gravel after imprevious material is placed in tie canal, Dr. Lauritzen pointed out |
