Release fish in quiet water, close to area where it was hooked. Never release lake trout. They are an exotic threat to the fishery. All lake trout you catch must be kept and killed. Bears, Backcountry, and Anglers Yellowstone is bear country, and there is no guarantee of your safety.
Bears often utilize trails, streams, and lakeshores.
Traveling alone in bear country is not recommended. Make enough noise to make your presence known to bears. If you should encounter a bear, give it plenty of room, detour if possible, or wait for the bear to move on. If a bear should charge or attack and the situation allows, climb a tree. If you are caught by a bear, try playing dead.
