Show Utah's 75 Water supply nearly average Utah's 1975 water supply ranged from "near average" on the Upper Sevier to better than three times average on Salina Creek according to provisional streamflow reports by the U.S. Geological Survey. Late spring snow melt produced more flow than forecast in most cases even though summer precipitation was only average to as low as 20 percent of average. Total annual precipitation for mountain stations ranged from near average to 30 percent above Fall reservoir storage (October (Oc-tober 1, 1975) is about 16 percent above average and 19 percent better than last year at this time. The 21 reservoirs, excluding Colorado River storage reservoirs, reser-voirs, used in this analysis are now 81 percent of usable capacity The streamflow forecasts made last May 1 as compared to provisional flows measured by the U.S. Geological Surveys, the Bureau of Reclamation, and Utah Power and Light Company read as follows: Coal Creek near Cedar City, May-July was 19.8 forecast and 14.8 measured flow; the Virgin River from Santa Clara near Pine Valley, May-June May-June was 5.1 forecast and 3.8 measured flow; the Virgin River from Virgin City, May-June was forecast at 54 and measured flow-was flow-was 32. |
