Surprising the Cedar River Chinook which is managed for a natural escapement is the most robust Chinook population in South Puget Sound and the only one with an average Recruits/spawner ration greater than 1 (actually replacing itself).

While the annual S/R is highly variable the average being above 1.0 makes it the only system outside of the Skagit and Snohomish basin meeting that minimal standard of productivity (note there were several PS systems where I could not find the S/R information).
