Fortunately it is <br />early in the season, and if the weather changes to a wetter pattern much of the basin could still <br />end up with snow amounts well above average by April I. Precipitation was only 53% of average <br />during December, and the water ycar total is 94% of average. There has been 26% more <br />precipitation than by this time last water ycar. Reservoirs in the basin have only 40% of their <br />average storage for this time of year. There is only 47% oflast year's storage. Early forecasts for <br />this year's runoff season are all below average at this time, Forecasts range from 80% of average <br />on the Colorado River at Dotsero, to 89% of average at the inflow to Ruedi Reservoir. <br />
