The most current stream-flow forecasts have a good news-bad news feel.
The good news is the forecasts for the April to July period are up 10 percent over the forecast released in March. The bad news is stream flows are still expected to be well below average through the end of the runoff period, which ends in July.The Colorado Basin River Forecast Center in Salt Lake projects northern Utah stream flows at between 50 and 65 percent of the 1961-1985 25-year average.
While March precipitation was close to 100 percent of average, the year-to-date average was about 70 percent. Stream flows were at 65 percent and reservoir storage was at just 60 percent of normal along the Bear River, Weber River, Six Creeks (Tooele area) and Provo River-Utah Lake drainages.
The Sevier and Virgin river drainages in southern Utah fared much better. March precipitation reached 110 percent to bring the year-to-date reading to 85 percent. The March stream flow was at just 35 percent although reservoir storage was at 85 percent.
Eastern Utah along the Green River is in probably the best shape. March precipitation mushroomed to 130 percent of average for year-to-date reading of 75 percent. Steam flow was at 70 percent and reservoir storage at 125 percent of average.
