National Fish Passage Program

Providing unimpeded movement, both upstream and downstream, for fish and other aquatic species is essential to their survival and life cycle completion. Most fish species within the Pacific Region make one or more seasonal migrations at various life stages to access habitat for spawning, feeding, rearing, or to seek cooler water. Barriers such as dams, culverts, irrigation diversions, tidegates, and other structures may affect passage or directly harm fish.

The goal of the National Fish Passage Program is to restore native fish and other aquatic species to self-sustaining levels by reconnecting habitat that has been fragmented by barriers. We employ a voluntary, non-regulatory approach to accomplish this goal. Each year we partner with other Federal agencies, states, Tribes, private land owners, local governments, and non-governmental organizations by providing technical assistance and funding for a variety of projects across the region.

Roy Creek, (North Coast, Oregon).          
Native fish from coho salmon to Pacific lamprey have unimpeded access to nearly 3 miles of quality habitat and Tillamook county has new, safer highway and railroad infrastructure now that a pair of culverts at the mouth of Roy Creek have been replaced with a 36-foot wide bridge. Read more here (pdf).

Replacing existing culverts on Tygee Creek with an 18-foot bottomless arch culvert allows fish to swim more freely becasue the bottom of the culvert is natural stream bed. (Credit: USFWS) Tygee Creek, (Eastern, Idaho).          
A recently-completed fish passage project in the Greater Yellowstone Ecosystem benefits a genetically unique population of Yellowstone cutthroat trout.  Now the Tygee population of cutthroat trout can enjoy 2.5 miles of pristine stream habitat. Read more here (pdf).

New bridges alon Deep Creek restore natural stream flow. (Credit: USFWS) Deep Creek, (Eastern Washington).          
Native fish, including bull trout and westslope cutthroat trout, and outdoor enthusiasts have occasion to celebrate with the completion of a fish passage project on Deep Creek in Washington.  By replacing problematic culverts with two bridges, the Service and partners restored access to 5 additional miles of quality stream habitat for fish and popular wilderness trails for people. Read more here (pdf).

Retrofitted water control structure in Waihee Stream Waihee, (Hawaii).          
Migratory native gobies now have new access to over a mile of high-quality stream habitat in Waihe'e Stream on Oahu's windward side now that the Service and partners have retrofitted a 78-year old abandoned water control structure. Read more here (pdf).

Ellsworth Creek, (Southwest Washington).          
Native coho salmon, Pacific lamprey, and other fish have additional habitat now that one of the last fish passage barriers in the Ellsworth Creek watershed has been removed. Read more here (pdf).
