Unusually long downstream movements totalling several hundred kilometres to >1100 km were observed during upstream homing migrations of radio‐tagged spring chinook salmon Oncorhynchus tshawytscha in the Columbia and Snake Rivers, U.S.A. Downstream migrants, identified by their repeated ascension and fallback over a series of large hydroelectric dams within the migration corridor, were primarily hatchery‐origin males.
