If the management objective is to reduce gear encounters with steelhead, then prohibiting fishing from boats makes sense. I think I've read that something like 70% of steelhead are caught by anglers fishing with guides who fish from boats. So a lot fewer steelhead are going to be hooked under this kind of regulation. Makes it tough for guides though. I wonder how guides will respond? Switch to walk-and-wade guiding, or get a non-resident OR guide license?
