Don't know the Nooch at all so just speculation... Has the hatchery changed their release sites from many to one? Know that a lot of other rivers are enduring that same thing. Snohomish basin used to have several release sites for summer steelhead. Now there is just one. Seriously impacts fishing in a lot of areas that would traditionally hold fish. Now instead of fishing over a "return" of summers to an area you are fishing on strays.
