Measurements are highly <br />variable throughout the basin, ranging from only 70% of average in the Saint Vrain Watershed, to <br />96% of average in the Clear Creek Watershed. Precipitation during February was the highest <br />monthly measurement this water year, at 130% of average. The water year total is now 89% of <br />average. Reservoirs in the basin remain extremely low for this time of year, at only 54% of <br />average storage. There is only 66% of the amount of storage there was last year at this time. <br />Unfortunately, despite the additional snow during February, the forecasted runoff has not changed <br />significantly from last months'. Forecasts range from only 35% of average at the inflow to Antero <br />Reservoir, to 76% of average on Boulder Creek near Orodell.
