These are the highest February 1 measurements since 1997. The <br />measurements range from 93% of average in the Dolores River Basin, to 129% of average in the <br />San Juan River Basin. Precipitation during January was 102% of the average, and the water year <br />total is now 94% of average. Reservoirs in the basins have a combined storage level of only 66% <br />of average, but hopefully, if favorable snowpack conditions continue into the runoff season, this <br />will improve significantly before the high water use season. Most of the streamflow forecasts for <br />the upcoming runoff season are near to above average. They range from 80% of average at the La <br />Plata River at Hesperus, to 107% of average at the Inflow to Navajo Reservoir. <br />
