<br />Precipitation <br /> <br />Precipitation measured at Colorado's SNOTEL sites was above average for February. <br />Statewide, precipitation was 121% of average, breaking a three-month streak of below <br />average precipitation for the state. Monthly totals were above average in all of the state's <br />major basins. Those basins reporting the highest percentages for the month include the <br />Arkansas, at 139% of average, and the South Platte, at 130% of average. In the remaining <br />basins, totals for the month range from 115% to 117% of average. With a return to above <br />average precipitation, the state's water year totals finally saw improvements. While all <br />consistently below average, all basins range from 82% to 89% of average for the five <br />months in the 2003 water year. Statewide, water year precipitation totals improved from <br />78% of average on February 1, to 87% of average on March 1. <br /> <br />Reservoir Storage <br /> <br />Reservoir storage saw little improvement during February. Storage volumes continue to <br />track well below average in all basins this month, with little to no significant increases in <br />storage. Storage volumes are the lowest, as a percent of average, in the Colorado Basin. <br />These volumes are only 36% of average and are 42% of last year's storage. In terms of <br />volume, this basin is also reporting the greatest deficit of any of the state's basins, with <br />476,000 acre-feet below the average mark for this time of year. The basin with the best <br />storage, as a percent of average is the Yampa, with 92% of average storage. However, with <br />only two reservoirs, with a total capacity of 42,000 acre-feet, this basin's high storage <br />figures are relatively insignificant in comparison to the remainder of the state. Statewide, <br />reservoir storage is now 54% of average and is only 61 % of last year's storage on this date. <br />The state's current storage is 1.57 million acre-feet below average. <br /> <br />Streamflow <br /> <br />Even with the additional snowfall during February, Colorado can continue to expect below <br />normal water supplies and runoff this spring and summer. The latest runoff forecasts call <br />for below average volumes at all forecast points. The state's best case scenario is in the <br />headwaters of the Colorado River, where forecasts range from 80% to 86% of average. <br />Forecasted runoff, as a percent of average, tends to decrease towards southern Colorado, <br />where many forecasts remain around 60% of average. All of these forecasts assume near <br />average weather patterns for the remainder of the forecast period. Should the state receive <br />below or above average precipitation in the coming months, these forecasts will be <br />adjusted downward or upward accordingly. Given these well below average forecasts for <br />most of the state, water users should anticipate shortages throughout the remainder of the <br />year. While improvements to these forecasts can occur yet this spring, reaching even an <br />average runoff remains highly unlikely this year. <br />
