American Brook Lamprey occurs in medium-sized and smaller streams with clean sand. It is found in the 11 watersheds around the outside edge of the state, where it is native. The Erie, Allegheny and Saint Lawrence watersheds have more records than elsewhere. Recent collections outnumber collections from earlier surveys and are likely the result of improved sampling techniques.
