Considerable precipitation along the Wasatch Front in April and early May will not dampen the likelihood of water shortages in much of Utah this summer, federal weather officials say.
The snowpack is still generally below average, reservoirs are only half full and streamflow forecasts remain below and far below average, National Weather Service meteorologist William Alder and Soil Conservation Service data collection supervisor Jon Werner said.The spring runoff is predicted to be 64 percent of normal statewide, an improvement of 2 percent to 7 percent since the end of March.
The improved outlook was most evident in tributaries that flow from the Wasatch Mountains into the Jordan River. But streamflow forecasts did not change during April in southwestern Utah and declined in southeastern Utah.
Forecasts for Bear River flows in extreme northern Utah also were discouraging - 44 percent, Alder and Werner said.
Many key reservoirs that provide culinary and irrigation water will not fill this year. On average, the reservoirs were at 51 percent of capacity and storing just 68 percent as much water as normal for the end of April.
A report from the two officials said individual reservoirs in their sampling ranged from 20 percent full at Scofield in Carbon County to full at Hyrum, Cache County; Vernon, Tooele County; and Huntington North in Emery County.
