How about a river like the Lyre. The bulk of the river flows through the park so the habitat has been fairly stable. I could be wrong but I don't know of any tribal netting there. Yet the steelhead have all but dissapeared there. Can the lyre river decline be put mainly on the shoulders of sporties overharvesting? There could be other factors I'am unaware of but the Lyre really stands out in my mind as a river that has declined due to nothing more than harvesting with no tribes involved.
