Show Sjisw Cover on Provo Biver fs Less Than 1838 April surveys show the snow cover on headwaters of Provo river is only G8 per cent of that of 1938, and only 54 per cent of the long-time average, according ac-cording to a report received Tuesday by County Agent S. K-Boswell. K-Boswell. The report was prepared by George D. Clyde, irrigation engineer, en-gineer, Utah state agricultural experiment station. Cooperating in making the surveys were the experiment station, U. S. weather bureau, state engineer, U. S. forest service, and the U. S. bureau bu-reau of agricultural engineering. To Affeot Lake "There has been considerable snow melting at the higher elevations, ele-vations, and most of the low snow has disappeared," the report re-port states. "The ground under the snow is saturated. With normal nor-mal spring precipitation and temperatures tem-peratures there should be no excessively ex-cessively high spring runoff." The probable runoff of Provo river will not exceed 100,000 acre-feet acre-feet for the April-September period, per-iod, or 29,000 for the July-September period, the report says. Melting this year is two to three weeks early. This, together with the absence of low snow cover, will materially reduce the amount of water reaching Utah lake. There is at present in the lake 463,000 acre-feet available for use. Therefore, it is belXd there will be ample water for all users under the Utah lake and Jordan river4 systems, according ac-cording to .the report. No High Water With normal precipitation and temperature, no excessively high water is expected from the American Am-erican Fork river, and the late season flow will probably be as much as 40 per cent less than in 1938, it is shown. Snow measurements at Dutchman station, sta-tion, South Fork station, Alta-mont Alta-mont and Timpanogos divide show the snow cover to be far under the 1938 standards. Snow cover on the Hobble creek, Payson, Santaquin creeks and Spanish Fork river watersheds water-sheds is only approximately 70 per cent of that of last year. The low cover has entirely disappeared, dis-appeared, but the ground is saturated sat-urated even under the high snow cover. The April-September runoff run-off probably will not exceed 65 per cent of that of 1938 in these streams. The snow cover on the drainage drain-age above the Strawberry reser- provide " a full water supply for all ' the lands under this system during 3 939, the report states. voir is only 70 per cejt of that in 1938. The hokluver storage in the Strawberry reservoir as of April 1 was 88,180 acre-feet, which is about 7.000 acre-feet more . than in 1038. The inflow to the reservoir probably will not exceed 75 per cent of that in 1E138, but this inflow, together with the hold-over storage, should |
