<br />The NRCS started plotting elevation vs. <br />SNOTEL Snow Water Equivalent (SWE). This <br />is interesting for the FTF and water managers <br />as these graphs tell whether the SWE is high or <br />low in the basin. This shows timing of the <br />snowmelt run out. For example, in the <br />southwest basins the highest SWE is still at the <br />high elevations making for a later run off this <br />season. <br />Also discussed was how high temperatures of <br />80-90 degree days assist in faster snowmelt and <br />higher stream flows especially at the lower <br />elevation SNOTEL sites. <br />Jack Byers, Deputy State Engineer stated that the <br />DWR has been working with dam operators in the Southwest, Gunnison, and on the Grand Mesa in the <br />Colorado Basin to evacuate storage in known high snowpack areas to help moderate streamflow and help <br />with flooding issues. <br />This was the 9th month in a row showing a decrease in the statewide reservoir storage deficit. In 2002 the <br />statewide reservoir storage deficit was nearly 1.8 million AF statewide and its now approximately 425,000 <br />AF statewide. <br /> <br />- 3 - <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />eolorado Statewide <br /> <br />350 <br /> <br />III <br /> <br /> <br />25Il <br /> <br />:m <br /> <br /> <br />,I , <br />, , <br /> <br />~ <br /> <br />150 <br /> <br />..

The National Weather Service has new graphical <br />products that show winds (yellow lines) and <br />precipitation events (in blue) for short term forecasts. <br />. Treste mentioned that currently there is a ridge over <br />the U.S. and a low pressure system off the coast with <br />low level winds. <br />. Tuesday May loth a new system will move in and set <br />up over Wyoming giving us a good chance for <br />precipitation in the northwestern part of the state mid <br />week. <br />.
