While these mcasuremcnts <br />are extrcmely welcome, they are still below the amounts ncedcd to significantly rcduce the reccnt <br />water shortages. Unfortunately, the snowpack is not likely to improve further unless this spring <br />scason is unusually wet. Measurements in the basin range from 85% of average in the Plateau <br />Creek Watershed, to 122% of average in the Willow Creek Watershed. Precipitation during <br />March was 131 % of average, which was the largest monthly accumulation this water year. The <br />water ycar total is now 97% of average. Reservoirs in the basin remain cxtremely low for this <br />time of year at only 36% of average storage for the end of March. Most of the stream forecasts <br />have improved from last month, and many are at or near average. They range from 78% of <br />average on the Roaring Fork at Glenwood Springs, to 108% of average at the innow to Willow <br />Creek Reservoir. <br />
