Section Of Yellowstone Feeder Canal Lined Viith flew Asphaltic Membrane; Es First Experiment Performed !n Utah Several weeks ago approximately approxi-mately 750 feet of asphaltic membrane lining was installed in the Yellowstone Feeder Ca-! Ca-! nal, which carries water from Gulch Irrigation Company, T. N. Todd Irrigation Co.. and Monarch Canal and Reservoir Co. The asphaltic membrane lining lin-ing material was supplied by Johns-Mansville Co., and since it was one of two' of the first projects of its kind ever at tempted in the west, several officials of-ficials of the company were in attendance while the project was under operation. The only other installation of this kind is at Lyman, Nebraska. Officials of the Johns-Manville Co. attending to assist in the installation in-stallation were Vice President E. J. Lyons, New York; George Clarvoe, technical adviser and head of the company's laboratories. labora-tories. New Jersey; Harry Brod-erson, Brod-erson, plant head at Pittsburg, Calif.; George A. Fritz, head salesman, intermountain area, San Francisco; and J. A. Fletcher, Flet-cher, Rocky-Mountain area salesman. sales-man. Assisting in the installation of the project was the Bureau of Reclamation, with Parley Neeley, of Spanish Fork, re-1 aional engineer, and John Shaw, technician from the Denver office, of-fice, directing the bureau's part of the installation. A 750 foot section was mada waterproof by the installation of a catalytically ' blown asphalt emulsion that was prepared and shipped from the company's refineries re-fineries at Cody, Wyoming. It was sprayed on the canal line section after it had been excavated exca-vated 18 inches deeper than the normal section. After spraying, the material was covered with gravel and clay. Closely identified with tha project was Louie Galloway, engineer for the Moon Lake Water Wa-ter Users Association, and from him comes the following information: infor-mation: "Experience has proven that there is considerable loss of water wa-ter in transient in the Yellowstone Yellow-stone Feeder Canal from tho Lakefork river to the point where the water is received by the irrigation companies at the top of the bench west of Mon arch. A particularly baa section in the canal is about three miles northeast of Altonah. ' , "The United States Congress appropriated money to be used for experimental purposes in connection with the soil and moisture conservation program. Some ofthese funds were allocated allocat-ed to the Bureau of Reclamation to be expended on Reclamation Reclama-tion projects. The officials of Region 4 of the Bureau of Reclamation, Rec-lamation, after a conferenc2 with officials of Moon Lake Water Wa-ter Users' Association (Moon Lake Project) entered into a contract con-tract with the Moon Lake pro- ject for the lining of a section j of the Yellowstone Feeder Cana, on an experimental basis. j . "So as to have comparative j costs on concrete lining and also to have information on maintenance mainten-ance costs along with the other two types of Lining, it was -decided to install 550 feet of concrete con-crete lining. The design for this concrete section was prepared under the direction of C. W. Lauritzen, in charge of research, Soil Conservation Service. Logan. Lo-gan. Mr. Lauritzen and his personnel per-sonnel supplied the technical supervision for the placing of this concrete lining, and the contractor con-tractor was Vernon Hurst, of Spanish Fork. Concrete lining has been used so long that it is not considered in an experimental stage, and the cost of this lining was borne by the Moon Lake Water Users' Association, except for the technical tech-nical assistance and a small sum furnished through the office of Mr. Lauritzen." "It might be borne in mind that the use of this new material from the Johns-Mahville Company Com-pany is the second installation in the west and the first in Utah, and the use of the catalytically catalyt-ically brown blown asphalt has been used extensively throughout through-out the west in other irrigation projects but is the first application applica-tion to an irrigation project in the State of Utah. These are demonstration plots or r of the canal and it is tf(. it wiil show what types of -ing should be used in the reaches of the Yellowstone er Canal."
