Since we are all too stupid to actually make an attempt to save our resources, why not implement a pay to play for each river? This is in addition to the annual required fishing license.

$25 a day to fish one particular river. You can pay by the day, week, month, or season. No fishing from a boat is allowed.

$100 a day to fish one particular river from a boat.

Established guides would either be to absorb this cost, or pass this one to someone who really wants to catch a wild steelhead. Many guides would not participate and thus reduce the amount of guided pressure on the river.

Once more, I'm super glad I don't own a boat.
