12
Stillaguamish/Deer Creek (Puget Sound ESU) 2002 status reflects improved overwintering habitat and increased parr-to-smolt survival and adult returns following the flooding in 1995 1992 – Critical; 2002 - Depressed

M. Columbia River ESU - Threatened
31

32
Yakima River (Mid Columbia River ESU) Unexpected up turn in wild escapement 1992 – Depressed; 2002 – Depressed

Conclusions Increase and maintain the number of Healthy stocks –How should we manage the 41 Depressed stocks? Multitude of “Unknown” stocks –Fisheries lost –Harvest no longer a source of data –2 year steelhead moratorium –Weather conditions make it impossible to survey most summer steelhead populations
