Sunbeam dam was removed totally. All that remains are some chunks of cement on the side of the river. This leaves the Salmon river as the longest free flowing river in the lower 48. No other fish has to go as far in terms of river miles from the ocean than these Sockeye. The steelhead and Springer also go this far. Not sure about your numbers thinker. They seem on the low side but I will look into it. I know that the Springers far outnumbered the 4136 total count you quoted for 1955. The total decline in that run can be directly traced the the 4 lower snake dams . Thanks for that post. It has some good info and I need to look it up.
