Freshwater Fishing.

The Thousand Islands stretch of the St. Lawrence River off Gananoque sits within Ontario Fisheries Management Zone 20 (Lake Ontario / St.

Lawrence River) — productive water for smallmouth and largemouth bass, walleye, northern pike, and the muskellunge fishery the Thousand Islands area is known for. Inland, the Cataraqui Region Conservation Authority's Gananoque River watershed lakes carry the same warmwater species under regional regulation.
