As for Wild Winter Steelhead I remember reading some field estimates on the Nisqually, Puyallup and Green the last 5yrs? Time travels fast. I wasn't able to find them again on a quick search, but remember the numbers are still down as are all of Puget Sound systems. Arguments have been made on what numbers give a green light for any fisheries? Keep in mind it's been roughly 20 yrs. since these were closed and they still have outgoing survival/return issues. I do know the Green had a March/April brood stock catch happening and it was productive. Not sure any more. I have a buddy that works at Centralia City Light and knows the Nisqually numbers at their diversion dam. They have showed some promise but then drop off see sawing yearly. I also know a guy that lives on the upper Puyallup. He sneak fishes C&R in spring and does pretty good. Also talked to a tribal bio, and the Puyallup's March fish have been doing better also, est. 1000-2000 a year returning. The newly renovated Clark's Creek Hatchery in Puyallup is going to start raising Winter Steelhead again, so maybe? Currently the Mucks and Puyallup tribes have a brood stock program on the White, around 30K smolt per year. They trap at Mud Mt./Tapps diversion and are getting 300 a year. Not that any of these rivers will be ever open again even for C&R but it does sound that they are showing some promise.I hope to cast again on any of these rivers before I die. Cross your fingers but don't hold your breath. Here are some links w/ some old Puyallup info.
