The Puyallup Herald features research by the Puyallup Tribe of Indians on salmon productivity in the Puyallup watershed:
Scientists with the Puyallup Tribe of Indians are looking at the impact of last winter’s floods on salmon species and results this spring aren’t good.
January’s floods along the Puyallup River and its tributaries washed away much of the underwater sediment that salmon need for successful spawning and subsequent migration. Russ Ladley, the tribe’s resources protection manager, said the flooding amounted to a record level along South Prairie Creek.
Here is the tribe’s most recent smolt trap report (which does not include results for this year). The tribe also produces a comprehensive report for salmon populations throughout the watershed.
