fishway
Dam bypass channel
A fishway is a structure that allows fish to pass around or through obstacles like dams, enabling them to reach spawning grounds upstream.
Also called a fish ladder, though fishways take various forms—stepped pools, channels, or elevators—depending on the species and terrain: The new dam includes a fishway for migrating salmon.
