The Colorado Length Record Fish Program recognizes the longest fish of a particular species that is caught and released by an angler, anywhere throughout the state of Colorado. However, northern pike and smallmouth bass caught in waters west of the Continental Divide will only be recognized for the State Record by Weight category. As a partner in the Upper Colorado River Endangered Fish Recovery Program and San Juan River Basin Recovery Implementation Program, CPW encourages anglers to catch and keep northern pike and smallmouth bass in most waters on the Western Slope of Colorado.
In this program records are by length (inches), as opposed to our other program, the records by weight, which does not allow for catch-and-release entries. The angler will fill out and return the application form (PDF), provide a picture of the fish on a measuring device and a witness signature on the application. This will be mailed to the Assistant Chief of Hatcheries in Denver.
The measuring device shall be behind or under the fish and not following the curvature of the fish.
