At Arizona’s Lake Havasu, one of the nation’s largest warm water fisheries projects provided fish habitat structures for more than 40 coves on the lake, affecting 875 surface acres. With support from Wildlife Forever, volunteers constructed netted boxes and PVC pipe structures. Along with the construction and sinking of the fish habitat structures, trails and handicapped accessible fishing docks were being built around the lake. Bass, crappie, and catfish are among the species benefiting from this project. Ninety-seven percent of anglers agree that fishing has greatly improved on the lake. The project has also been credited with saving two endangered species of fish — the bonytail chub and razorback suckers.
