The Salmon River derives its name from the landlocked Atlantic salmon which were of great importance to Native Americans and early settlers of the region. However, these native salmon were extirpated from the river by 1872 and from Lake Ontario by 1898. Since the late 1960s, the Salmon River has been stocked primarily with Chinook salmon, coho salmon, steelhead, and brown trout, in addition to a smaller proportion of Atlantic salmon. These fish return to the river for annual spawning runs after spending a majority of the year in Lake Ontario.
