Denham,

The Colvilles are not a treaty tribe and do not have treaty fishing rights. They have fishing rights on their reservation. So their approach to fish management is different than that of most of the treaty fishing tribes.

As for modifying treaty fishing rights, that is the pervue of Congress. That was tried in the early 1980s and flopped miserably. On the national level, the public is highly supportive of tribal rights.
