Nothing destroys a river ecosystem like a large dam, but every stretch of creek and river we can reopen to migrating steelhead means more fish spawning on the gravel.

Are there resident steelhead in Hood Canal!? Vertical distributions of migrating steelhead smolts have not been well documented, but juvenile salmonids are known to primarily inhabit the upper 12 meters of the marine water column [24], and are thus likely to encounter the submerged pontoons of the Hood Canal Bridge (HCB).

The Washington Department of Fish and Wildlife IMW program is designed as a Before-After Control-Impact (BACI) study in order to determine whether and how habitat restoration activities influence abundance of salmon and steelhead.
