For updates on fishing and launching conditions, call the recorded Bear Lake hotline at 435-946-8501. Remember, in order to keep a cutthroat trout from Bear Lake it must have a healed fin clip (usually the adipose fin). If you catch a cutthroat with all of it's fins intact -- even if it's tagged -- you must release it. In order to maintain the fishery, consider releasing large lake trout. In Bear Lake, lake trout can easily live more than 35 years.
