CommentsMorgan Lake periodically overflows into the San Juan River, a major tributary to Lake Powell. Gizzard shad are present in the upper portions of Lake Powell and biologists predict that within 2-5 yrs, this species will be established throughout the lake. Gustaveson estimates that 2000 gizzards exist in Lake Powell based on the 6 specimens netted in the San Juan River arm of Lake Powell.
