All waters west of the Continental Divide (as well as Midvale Creek in the Two Medicine River drainage and Wild Creek in the St. Mary River drainage) are subject to catch and release fishing only for cutthroat trout. Cutthroat trout must be handled carefully and released immediately back into the water. However, two cutthroat trout may be harvested from Hidden, Evangeline, and Camas Lakes in accordance with park fishing regulations. No bull trout may be retained and any caught incidentally must be immediately released.
