Colorado Parks and Wildlife has enacted voluntary afternoon fishing closures on the Lake Fork of the Gunnison River, Tomichi Creek, and Cochetopa Creek as drought, low water, and rising temperatures place increasing stress on trout populations.
Voluntary half-day closures are in effect on the Lake Fork of the Gunnison River, Tomichi Creek, and Cochetopa Creek to help protect fish during extreme heat and low water conditions.
Colorado Parks and Wildlife (CPW) has enacted voluntary half-day fishing closures on three popular Gunnison-area waterways as drought, low streamflows, and rising water temperatures place increasing stress on trout populations.
Effective Friday, July 10, anglers are asked to avoid fishing from noon until midnight on the Lake Fork of the Gunnison River, Tomichi Creek, and Cochetopa Creek until further notice. Fishing remains open during the cooler morning hours, when water conditions are less stressful for fish.
CPW has posted signage at all three locations and says the voluntary restrictions are intended to protect fisheries while allowing anglers to continue enjoying the waters responsibly.
During summer, rivers with unusually low flows can warm rapidly throughout the day. Higher water temperatures reduce oxygen levels and make it much harder for trout to recover after being caught and released.
According to CPW aquatic biologist Giulio Del Piccolo, this year's drought has created particularly challenging conditions.
"Cochetopa and Tomichi have been incredibly impacted by the historic drought this year," Del Piccolo said. "The Lake Fork also sees a lot of fishing pressure from anglers. Between high temperatures and low-flow conditions, it is important to protect these fish populations."
Conditions on all three waterways are well below normal.
On the Lake Fork of the Gunnison River, which is under a voluntary closure below Lake San Cristobal:
Meanwhile:
CPW says trout in both streams have shown visible signs of stress during the hottest parts of the day.
Rather than closing the fisheries completely, CPW chose a half-day voluntary closure so anglers can still fish during cooler morning hours when conditions are safer for trout.
The agency says this approach may help avoid mandatory fishing closures later in the summer if conditions worsen.
CPW biologists will continue monitoring water temperatures, streamflows, dissolved oxygen, and fish health over the coming weeks.
Mandatory closures may be implemented if any of the following occur:
CPW encourages anglers to adjust their fishing practices during hot summer conditions to reduce stress on fish.
Recommendations include:
While these voluntary closures remain in place, anglers looking for alternative destinations can use CPW's Fishing Atlas, which highlights more than 6,000 miles of fishable streams and over 1,300 lakes and reservoirs across Colorado.
Officials emphasize that following the voluntary restrictions now can help preserve healthy trout populations and keep more fisheries open throughout the remainder of the summer.
