SAN LUIS VALLEY – As temperatures around the region continue to break historical records, Colorado Parks and Wildlife (CPW) is preparing for a stressful season for local aquatic life. Snow is melting almost two months early, raising river and stream water levels around the Valley but the increase in water won’t last long and the result could lead to fishing closures. 

“This is a big conversation we are having right now,” said CPW Aquatic Biologist Estevan Vigil. “Patterns looking forward are not looking good. We are at 28 percent of median snowpack and that does not bode well for fishing.” 

According to Vigil, CPW has plans in place based off scientific data to monitor both the Rio Grande and Conejos rivers as summer approaches. 

“Per state guidance and scientific data, we may be looking at fishing closures this year because of high water temperatures. Once a river reaches a certain temp, we have to do voluntary closures in order to minimize the stress on fish and aquatic resources.” 

Several gauges are in specific locations on both rivers which will help CPW monitor water temperatures and help determine if a closure needs to be put in place. 

“We use a flowchart that determines closures based on scientific proof that a closure is needed. We want to avoid full closures if we can, but we have had to do it before in the past.” 

CPW is hoping for a change in the pattern and is asking anglers to work with them to minimize stress on fish during this time. 

“Fish can appear not to be stressed but can be under duress even in catch-and-release situations where the fish swims away. It is likely under these circumstances that the fish will swim away, only to later die.” 

While CPW will be monitoring the rivers, they are also asking anglers to use common sense when fishing smaller streams. 

“Once a stream reaches 71 degrees, the stress on fish can be devastating to populations. We recommend fishing in the morning or going into higher elevations to fish larger and deeper bodies of water.” 

Notice will be placed in locations where a closure is put in place. “We are asking folks to be aware of these closures. Check our websites, call and talk to local organizations like chambers or visitor centers to get fishing reports and help us make it through this year.” 

Vigil stated that forecasts for the coming summer season are unlikely to change unless weather patterns shift and bring moisture and cooler temperatures to the region.
