If you ban boats there will be more wading. Redds would suffer too. If you ban wading then more will crowd the very limited bank accessible spots. The pressure on those spots would result in more riverside habitat damage as people tried to make more space, faster access, etc. I'm all for bait bans. If a river or whole system must be shut down to allow a few years of recovery to happen that might be the best method. Interesting subject Mr. Triggs, interesting comments have resulted.
