Do you support voluntary fishing closures to help protect local fish populations during extreme weather?

Colorado Parks and Wildlife ended voluntary fishing closures across 11 river sections within its Southwest Region. The decision follows recent cooling trends and increased rainfall that improved the health of local fish populations.

Why it matters

The closures were originally implemented during the summer of 2026 to protect fish from heat-related stress when water temperatures rose above 70 degrees. Lifting the restrictions allows anglers to return to these waterways now that conditions have stabilized.

Colorado Parks and Wildlife lifted voluntary fishing restrictions on 11 specific river sections in the Southwest Region. These measures were enacted during the summer of 2026 when water temperatures consistently exceeded 70 degrees.
