<br />4 ~ <br /> <br />2 <br /> <br />The !Asy 1st reading on Utah Lake was 3.89 feet above compromise. This is a rise <br />of 0.49 feet since April 1st and is 1.19 feet higher than a year ago at this <br />time. Inflow to Utah Lake during April was 183,400 acre-feet, 245 percent of <br />normal. April outflow was 100,200 acre-feet, almost six times normal. Utah Lake <br />is expected to rise to a level 5.00 to 6.00 feet above compromise late this <br />Spring. <br /> <br />SOUTHERN UTAH: Water supply forecasts in southern Utah remain well above normal, <br />ranging from 120% in Coal Creek near Cedar City to 800% on the lower Sevier <br />between Sigurd and Gunnison. The Virgin River basin is the exception, where <br />forecasts were below normal. <br /> <br />April precipitation on the Beaver and lower Sevier basin was well above normal, <br />while the Virgin and upper Sevier basins were well below normal. Hatch reported <br />only 14 percent. On the other hand the area from ~Mnersville north to Kanosh <br />and Fillmore that has been hit hard with precipitation all winter received <br />abundant amounts again in April. Minersville reported 240 percent of normal, <br />Kanosh, 247 percent and Fillmore, 231 percent. Seasonal precipitation, October <br />thru April. follows the same pattern as the monthly. The Virgin and upper Sevier <br />basin has below normal precipitation, while the Beaver and lower Sevier drainages <br />received above normal amounts. The Minersville to Fillmore, Kanosh areas reported <br />175 to 200 percent of normal. <br /> <br />Snow measurements on !Asy 1 remain above normal with the exception of the Virgin <br />River basin. Some average basin snowpacks include: Upper Sevier - 131%; Lower <br />Sevier - 226%; Beaver - 177%; and Virgin River Basin - 73%. <br /> <br />April runoff continues to be well above normal with flow on the Sevier at Hatch <br />_ 114% of normal; inflow Sigurd to Gunnison - 816%; Sevier River at Gur~ison - <br />656%; Sevier River at Kingston - 277%; East Fork of Sev~er at Kingston - 297% <br />and the Beaver River at Beaver - 172%. <br /> <br />Reservoir storage in the Sevier Basin is slightly lower than April 1st, but <br />remains well above normal with the combined contents of Otter Creek, Piute and <br />Sevier Bridge Reservoirs at 89% of capacity and 148% of the May 1 average. <br /> <br />Flood potential remains very high particularly ill the San Pitch, lower Sevier <br />and Beaver basins. If abnormal spring rains or warm temperatures should <br />materialize, flooding could be more wide spread in low lying areas. <br /> <br />EASTERN UTAH: Water supply outlook is for above normal streamflows during <br />this ye~rs snowmelt. Forecasts ranged 114 to 188% in the Duchesne basin to <br />greater than 200 percent for drainages along the east slopes of the Wasatch <br />Mountains. Flood potential varies in eastern Utah, but is the highest in <br />Huntington, Price, San Rafael drainages. <br />
