the record is 42 pounds 2 ounces taken off bell island alaska by a kid. the reason it would be hard, is because most people use 10 lb. test line while fishing for steelhead. the first thing that fish does will be to head for either the ocean, or a sunken root wad. it would be easy to do it in the salt water, but not so easy to do in the fresh water. its hard enough catching a 30 pounder, imagine catching a 50 pounder.
