Great Salt Lake Basin
Near to much above average runoff volumes were observed throughout the Great Salt Lake Basin for the April-July period. Early season forecasts mirrored the much below average snowpack conditions resulting in forecasts that were too low. The snowpack increased into March but remained near to below average during much of the spring. Forecasts continued to indicate below average runoff expected. Conditions similar to 1998 occurred from May into June, with cold late spring storms maintaining and increasing the snowpack. The unusually wet weather gave way in mid June and the delayed runoff conditions resulted in larger peaks and volumes than were anticipated.The majority of observed runoff values fell within the 10 percent and 90 percent exceedence range of the forecasts issued between March and June.
