Historical salmon runsPre 1800’s
• 5000 Chinook• 23,000 Coho• 60,000-100,000 Chum• 115,000 Pink (odd years only)• 6000 Steelhead
720,000 to 1,425,000 lbs/yr!!!!! marine derived nutrients; depending on chum run and pink(odd year)
Present Day• 1500 Chinook• 5000 Coho• 30,000 Chum• 10,000 Pink• 500 Steelhead
343,000 lbs/yr
• Less than 1/3 of historical run size• Much more chum than any other fish = less
diversity
Our goals…
• Upstream nutrients
• Winter months
• Increase nutrients in low nutrient upper watershed
