On any Lake Ontario stream, you are allowed to take no more than one steelhead per day with a minimum length of 21 inches. The only exception is on the Niagara River in which anglers are allowed three fish per day with same 21-inch minimum. As for the Lake Erie tributaries, anglers are allowed to take three fish per day with a 12-inch minimum size.
Rule to be Followed at All Times
No matter if anglers are on a Lake Erie or Lake Ontario stream, they cannot snag or attempt to snag a steelhead. Foul-hooked fish must be released immediately, and anglers are not allowed to corral, kick, drive or kick fish from their concealment.
All New York tributary regulations are in effect from Sept. 1 through March 31, with the exception being the Salmon River in Oswego County, where the effective dates are Aug. 15 through April 14.
Anglers are not allowed to night fish for steelhead in New York waters, including the Great Lakes and its tributaries. This rule takes effect 1/2 hour after sunset to 1/2 hour before sunrise.
Steelhead anglers cannot use hooks that have a gap larger than 1/2 inch from the hook point to the hook shank. Also, anglers must use single hooks, with the exception being floating lures, in which treble hooks are allowed.
