Most recent Connecticut River Basin Fishway Passage Counts
Fishways have opened up hundreds of miles of river to migratory fish in the Connecticut River watershed! We know this because we count the number of fish passing through these structures. Knowing how many fish and what species use these fishways helps us make decisions on how to best restore our migratory fishes.
