Apparently confined to the St. Lawrence/Champlain watershed in northern New York as well as the larger lakes in central New York and the depths of Lake Ontario.

This is a northern species found from the Arctic Circle southward to Connecticut and Minnesota. It seems seems to have been extirpated from states further to the south (e.g., Indiana, Pennsylvania).
