No need to enforce the regs if they increase the cost of the stamp to such and extent that those who rely on fishing to reduce food costs can't afford it. There are plenty of warm water species and waters that they can fish for to stock their table. No need to do it with trout. Besides, after the first few miles below the dam the warm water species show up. Let them fish further down the river. There is plenty of access to warm water fish, especially relative to trout.
