Rivrguy's description happens more than once. This sounds like the old McAllister Creek hatchery that had planned to use the McAllister springs which are/were one of the water supplies for the City of Olympia. Only problem was that Olympia wasn't on board so they had to move downstream. Ended up with nearly every kind of disease known in fish culture including saltwater diseases (because of tidal influence in the creek). Despite being operated by some really good fish culturists, the place never really could be effective. It finally closed with a lot of the WDFW folks kicking and screaming all the way.
