GLENWOOD SPRINGS, Colo. — Low flows and high water temperatures are creating critical conditions on the Upper Colorado for the second consecutive year, triggering fishing closures amidst reports of struggling and dying fish. Anticipating these conditions, the Colorado River District chose to release water from an already-reduced Wolford Mountain Reservoir last weekend. This voluntary release generated approximately 200 acre-feet of water to protect the health of the river – and by extension, local economies and downstream water users. District staff, however, says further action is needed.
“Our constituents are seeing fish floating by belly-up and struggling to survive current hot temperatures,” said Brendon Langenhuizen, the River District’s Director of Technical Advocacy. “We’ve also received reports of dead fish along the riverbanks. Since the beginning of July, these new-normal conditions are having major impacts on the Upper Colorado River ecosystem. Colorado Parks & Wildlife’s fishing closures are symptomatic of a larger issue that needs the attention of all water users. Our District has and will continue to do our part with voluntary releases when water is available from our limited resources at Wolford Mountain Reservoir.”
Recent monsoonal rains are bringing some relief, but soil moisture issues and hot, dry conditions forecasted for early next week have prompted a need for direct action. In response, the River District began releasing an additional 50 cubic feet-per-second (cfs) Friday morning, July 15, and will continue through Sunday, July 17, providing another 300 acre-feet of water for the river by Monday morning. Limited West Slope water supplies will inhibit the River District’s ability to fully address temperature and flow issues, however.
“We can’t fix this situation alone,” Langenhuizen stated. “Our constituents are asking for help to address the river’s unhealthy conditions causing fish kills. They’re wondering why large Front Range providers are not reducing their transmountain diversions to join the River District in aiding Colorado’s namesake river and the livelihoods it supports.”
The River District urges these water providers to act in partnership with West Slope water users to protect the health of the Upper Colorado River.
