Precipitation in December 2007 was 255% of average followed by 160% of average in January 2008, and then 130% of average in February. The seasonal precipitation is 120% of average. Snow pack decreased from 140% of average on February 1st to 130% of average on March 1st. This equates to 110% of the seasonal snowfall accumulation. The runoff forecasts for April-July 2008 range from 107% to 124% of average. This reflects a slight drop over last month's forecasts resulting from the slight drop in average snowpack throughout the Sevier River Basin.

Differences between the full period forecasts and the residual forecasts may not exactly equal the actual observed volumes due to rounding conventions (see Definitions section).
