The snow measurement indicates that there is only I % of average snow <br />accumulation left in the Basin on June I. The snowpack measurements had peaked in late March, <br />at about 50% of the average peak, and the warm, dry conditions that have persisted through most <br />of the spring have caused the snow to melt out about 30 days ahead of the average melt out date. <br />The precipitation during May was only 66% of average, which was the best monthly <br />accumulation of any basin in the state. The water year total is now 60% of average, which is only <br />70% of the water year total last year on June I. The combined reservoir storage has diminished <br />significantly since last month, and is only 72% of average on June I. There is about 22% less <br />storage then there was last year at this time. The streamflow forecasts have been lowered even <br />further than last month's forecasts. They now range from only 9% of average at the Inflow to <br />Antero Reservoir, to 41 % of average at the Big Thompson River at mouth near Drake. <br />
