The Nisqualy may have dams but there is some evidence and agreement that there was an impassable barrier now beneath LaGrande. Flows were certainly disrupted but linear habitat is still there.

The loss of Muck Creek, I have been told, was huge. It used to produce tons of smolts. Now, not so much.

As to actually stocking hatchery fish, I think that was only done in a couple of years and certainly not over the long run seen elsewhere.

It is probably the single best PS river (maybe statewide) to make into a gene bank system where the remaining genetics are closest to what was originally there. And, those fish have had access to all the river so they could evolve with it.
