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.
