While melting has resumed, the measurements basin-wide remain above averagc at <br />105%. This amount is nearly four times the amount of snow there was last year at this time. <br />Measurements in the basin range from only 72% of average in the Roaring Fork Watershed, to <br />167% of average in thc Willow Creek Watershed. Preeipitation during April was 118% of <br />average, which was the third month in a row with above average precipitation. The water year <br />total is now 101 % of average. Reservoir storage in the basin is slightly better than last month, but <br />rcmains extremely low for this time of year at only 42% ofavcrage. Many of the stream foreeasts <br />have improved from last month, and many are above average. They range from 78% of average on <br />the Roaring Fork at Glenwood Springs, to 118% of average at the inflow to Willow Creek <br />Reservoir. <br />
