Where are the core populations of humpback chub located in relation to the trout fishery?
The area managed for recreational trout fishing, occupies the first 15.5 miles of the Colorado River below Glen Canyon Dam. The confluence of the Little Colorado River and the Colorado River, which is a critical area for humpback chub, is located deep in the Grand Canyon approximately 60 miles downstream from Lees Ferry. Here, efforts are being made under the Adaptive Management Program to conserve and enhance humpback chub populations, including the removal of non-native trout.
