Right on Salmo, that an organization which supposedly has something to do with fishing would support the destruction of fish habitat is beyond belief and represents the absolute depth of ignorance.

A snagger kills the fish one at a time. A gillnetter gets most of them one day at a time. A habitat destroyer gets them all, every day, forever.

Just the simple act of floating down the river, encountering the one tree large enough to fall across the river and temporarily block it to navigation, and cutting it in two with a chain saw, eliminates the chance of that key piece of wood surviving the next flood to embed itself, provide stability, and provide shelter. Each individual act in total results in denuded, unstable streams that become increasingly devoid of in-stream habitat and fish. As they become unstable they begin to meander wildly, encounter developments, and eventually become armored and totally unproductive. We have lost so much productive capacity already that without actively placing wood in the rivers, and actively protecting what is there, there is little chance of wild fish recovery, or even of hatchery fish survival.

I'd say what we need is sanctuary areas in each river system where all boating is prohibited. We also need sanctuary rivers - those few that have good wood, and the few more rivers that are too small to be floating safely without having to cut wood out of the way, should all be closed to floating with any kind of boat. Apologies to you who feel threatened by this idea, but if you want to fish, you first have to have something to catch, and you won't if your actions destroy habitat.
