Chinook Salmon can be found in Lake Oahe and Oahe Tailwaters due to the cold, deep water habitats. In South Dakota, they primarily feed on rainbow smelt and lake herring.
Chinook Salmon have streamlined, torpedo-shaped bodies with black gums and sharp teeth. The top of their body is blue-green fading to silver sides. Dark spots are restricted mostly to the top of the head, back, and dorsal and tail (caudal) fins. Breeding adults become a dark reddish-brown color.
Limits apply to any combination of trout, salmon or splake.
