Interested parties are hereby notified that the U.S. Army Corps of Engineers, Portland District (USACE) is seeking public comment on the draft Environmental Assessment (EA) on upgrades to the Dexter Fish Facility in Lane County, Oregon that would improve fish collection, handling, and transportation for the benefit of salmon, summer steelhead, and trout.

USACE is proposing to upgrade the existing fish facility and associated support structures, including the access road, maintenance buildings, and access bridge. Facility upgrades include the following feature improvements:
•Fish ladder and auxiliary water supply diffusion chamber
• Forebay intake juvenile screens
• Pre-sort pool and shade structures
• Post-sort pools
• Truck loading and bridge access replacement
• New facility support buildings
• Facility water supply pipe
• Fish return to river pipe
