How do yo have that in PS with the Puyallup and Green? River banks man made diked for flood control with the damns built. Freeway raceway flow habitat...habitat gone since 1930's. Green diked and damned in the 50's. Both lower river habitat is and has been gone for 70-90 yrs.. And yet both rivers still provided a viable steelhead recreational fishery into the 90's with wild and hatchery fish plentiful. The Steelhead adapted to that disruption until the predators numbers began to increase with there protections. IMO if you kill 10,000 cormorants and seals in PS. You will see an increase in all fish returns. The trouble is no one has the stomach or political will for it! Tribes time to answer with immunity!
