Lot of things done right down to moving fish around. Bingham ( EF Sats ) Coho were put throughout the watershed by the millions a year.

But with Chinook .........The second Satsop Hatchery was a pumped station across the river , just below the bridge at Schafer Park. The remaining gravel bottom / concrete standards are West of the river in the field across from the Beerbower Road. One year, old records show, 50 million eggs were taken and transferred to the old Upper Chehalis Hatchery but something went wrong and they perished. That may be the year age group wipe out someone referred to earlier.

What is missed is this. Prior to Simpson being built in the 50's, now Bingham, the East Fork Satsop was primarily a Chinook stream. Late Coho to the dry run and Bingham Creeks and a normal run timing of late November for Coho. T day fish we called them when I was a kid. Run compression, stock manipulation, stock importing, and massive out plantings of fry and smolt, all designed to provide greater harvest altered everything ............... shall we say a lot. What those who did not grow up around here think is normal or native or wild ( depending on definition ) is more than likely not so. Long history, lot of players.
