There is only 87% of the amount there was last vear at this time. The <br />~ '" J <br /> <br />measurements are highly variable, ranging from only 65% of average in the Upper South Platte <br />\Vatershed, to 82% of average in the Clear Creek \Vatershed. Vv11ile measurements are well above <br />the record lows at this time, without a very wet spring, water shortages are almost assured for <br />many areas in this basin. Precipitation during February was 83% of average, and the water year <br />total is only 73 % of average. _ The combined reservoir storage for 31 major reservoirs in the basin <br />is 83% of average, \,,'hich is about 53% more storage than last year at this time. The streamflow <br />forecasts for this runoff season do not provide much hope to ease any water shortage issues. All <br />of the streamflow forecasts for the runoff season remain below, to much below average at this <br />time. They are highly variable ranging from only 22% of average at the Inflow to Antero <br />Reservoir, to 91 % of average on Boulder Creek near Grodell. <br />
