![]() “Once we got the all the funding in place, the rest of the project went relatively fast,” said Dennis. A brand new Doppler radar was built on the San Luis Valley Regional Airport property in September last year. “It was a very exciting project to work on because all the players that came to the table wanted to be there, and everybody put in something,” said Gigi Dennis, the Alamosa County Administrator.ĭennis said various state agencies, counties, and water districts came together to get the project off the ground. Knowing that the radar data helped them better estimate how much water was available in the snowpack, the next step would be to get their own radar. Simpson said they rented that radar for five years, and over that time they saw very accurate streamflow forecasts based on their new data. “That person would have to go down to the airport, crank up the unit, and start capturing radar data.” “They usually had to wake someone up, usually someone from the local university,” said Simpson. Every time there was a storm coming in, they had have a person go out to the radar site to get it running. It was a basic radar system that needed quite a bit of attention, but they were determined that some hard work would pay off in the future. They had to bring in a radar to help forecast how the weather was changing that fire,” said Simpson.Īfter that fire, the Conejos Water Conservancy District decided to rent that radar, move it to Alamosa, and try an experiment to better estimate the amount of snow that fell in there basin. ![]() “That year in 2013, there was a significant wildfire in the area called the West Fork Complex Fire. Now all they needed was access to Doppler radar. ![]() “We said why don’t we see if we can adopt that to snowpack here,” said Simpson. Simpson said the streamflow estimates could be off as much as 20-30% making it difficult to manage the rights to water during the summer.Ībout seven years ago, Simpson heard about improvements being made to software and computer modeling that estimate precipitation totals based on Doppler radar data. “The diversions out of those river systems are what build and support our aquifer system here, and we depend on our aquifer system heavily,” said Simpson. Simpson said they are obligated by state compacts to allow a certain amount of water pass through the Colorado border every year along the Rio Grande and the Conejos Rivers. “We get less than seven inches of precipitation all year, so we are very dependent on snowpack.” “Right here on the valley floor, it’s really one of the driest places in the state of Colorado,” said Simpson. There is a critical need to know how much new water will be available each year. So there is essentially no weather data available below 10,000 feet. The other radars are blocked by mountains as well, one in Denver, one in Albuquerque, and another on the Grand Mesa. ![]() And the Wet Mountains and the Sangres block the radar beam. The closest National Weather Service (NWS) radar is in Pueblo County, more than 90 miles away.
