Hot Sulphur Springs, Colo. — Colorado Parks and Wildlife (CPW) is seeking public input on proposed changes to fishing regulations in Grand and Summit Counties through Monday, July 21.
In Grand County, CPW is proposing to remove size and bag limits for tiger muskie in Lake Granby, Grand Lake, and the Colorado River between Shadow Mountain Reservoir and Lake Granby. Currently, by default, the statewide regulation applies, which is a limit of one fish over 36 inches. Aquatic biologists have documented the presence of tiger muskie in the Colorado River between Shadow Mountain and Lake Granby, and members of the public have also reported catching tiger muskie in Lake Granby near the Colorado River inlet. These changes would allow anglers to assist CPW in managing the tiger muskie population in these waters.
CPW first introduced sterile tiger muskie into Shadow Mountain Reservoir in 2023, and does not manage for this species in the surrounding bodies of water.
In Summit County, CPW is proposing to change the timing of the seasonal fishing closures on the Blue River and Tenmile Creek, upstream of Dillon Reservoir. The new proposed closure dates are from September 15 (currently September 1) to December 1. CPW aquatic biologists believe this change will not significantly impact the spawning of brown trout, which peaks around October 1. These proposed changes will provide an extended fishing season in these waters while still offering reasonable protection for spawning brown trout.
“Public feedback is critical in formulating new and updated regulations,” said Hot Sulphur Springs Area Aquatic Biologist Jon Ewert. “Ongoing input from anglers has led us to review these regulations and propose changes that align with our management goals while allowing for expanded angling opportunities at these water bodies.”
Public feedback on the proposed changes to fishing regulations in Grand and Summit Counties is open through July 21. Questions and feedback can be sent to NW Region Senior Aquatic Biologist Ben Felt at [email protected] and Hot Sulphur Springs Area Aquatic Biologist Jon Ewert at [email protected] with “Feedback on proposed fishing regulation changes” in the subject line.
