Aces and Eights and Valsdad, I think you guys make some strong arguments for recovery and optimism...and here's one more arrow for your quiver, unique to Siskiyou County and the Sacramento system and it's tributaries. The salmon and steelhead populations did survive and adapt...with a history of hydraulic gold mining from 1849 to 1884. We literally turned mountains to mud and flushed them down every major river on the Sierra. The salmon survived.
