Show USAC Publishes Booklet on Delta Canal Lining Shows Clay Packing To Be Impervious To Water and Holding Up 1 A technical bulletin is being published pu-blished by the Experiment Station at the U.S.A. C. for people of Millard Mill-ard county, concerning interesting experiments on canal lining made by Dr. O. W. Israelsen, Research Professor of Irrigation and Drainage Drain-age at the Utah State Agricultural Agricultur-al College. Recently Dr. Israelson spent a week in Delta to study the permeability perme-ability of the clay lining which was placed in the Delta-Melville companies' C canal during April 1941. Permeability measurements made immediately after completing comple-ting the lining showed that the compacted clay was very resistenl to water flow. It would require about 12 years for one cubic foot of water to flow through a square foot of the bed of the canal. Recent sludies indicated that the clay soil is still very low in permeability, there being substantially substan-tially no change since 1941. The permeability of the natural sand underlying the clay, through which the canal was originally built, on the average is 10,000 times that of the clay lining. Ground water studies in the vicinity of the canal ca-nal also indicate that the clay lining lin-ing has greatly reduced seepage losses. i The information contained in this bulletin will be of vital importance im-portance to the Irrigation Companies, Com-panies, the Drainage Districts, and to the Farmers in general. Water seepage losses in canals near Hinckley, Sutherland and Su-garville Su-garville were also made. The. records re-cords kept on the B-canal for a distance of one and one fourth miles showed a loss during one irrigation season of 457 acre feet of water, or enough water to irrigate irri-gate 300 acres of land for one season. sea-son. If this seepage loss could ' have been prevented and the wa-' wa-' ter rented at $1.50 per acre foot, it would have netted the stockholders stock-holders $678.00. 1 But this is not the only loss the 1 farmers sustained by this canal i seepage. The lands adjacent to ' the canal were more or less water-' water-' logged, rendering them unproduc-l unproduc-l five, making it necessary for the ' Drainage District to extend their open drains into the area to re-' re-' lieve the waterlogged condition at 1 a cost of approximately $1,500.00 per mile. i These experiments having been , made and soon to be published, will be of vital importance to the Delta area in planning Post-War ' labor activities.
