Bighorn Canyon National Recreation Area was established by an act of Congress on October 15, 1966, following the construction of the Yellowtail Dam by the Bureau of Reclamation. Bighorn Lake extends approximately 60 miles through Wyoming and Montana, 55 miles of which are held within spectacular Bighorn Canyon. The Recreation Area is composed of 70,000+ acres, which straddles the northern Wyoming and southern Montana borders.

The Afterbay Lake below the Yellowtail Dam is a good spot for trout fishing and wildlife viewing for ducks, geese and other animals.
