You don't have to fish within 75M of the dam to be in an accessible shore fishing area in Caledonia. Therefore, nobody needs to break any laws, or waste time 'hunting' steelhead.
I don't fish steelhead really at all anymore. I have a real problem with tromping through fish nests to disturb a natural migration of fish. I for one, think it's ridiculous guys can walk across trout eggs all season but heaven forbid a guy catch and release a bass in April.
BTW fishing at Caledonia is very slow this year. Early runs put fish way upstream. Good reports even further than Brantford from some people this year.
