Footnotes
- Wild forecast includes hatchery origin and natural origin fish
- Combine hatchery and natural forecasts
- This includes returns to Samish, Whatcom, Nooksack and Lummi Bay and neighboring streams.
- Forecast resulting from rearing pond production spawning in river of origin or in neighboring streams
- Combined natural and hatchery spawner forecast (all fish of hatchery origin)
- Last releases from BY 2001, no fall chinook are expected
- Hatchery chinook releases terminated with BY 2000. 2008 forecast is wild production of naturally spawning hatchery fish.
- RER= Recovery Exploitation Rate (interim management ceiling during recovery phase).
- Level of spawning abundance that triggers additional management action.
- The low abundance threshold includes 800 natural and/or 500 hatchery spawners
