Osoyoos Lake (5,723 acres, 2,036 of which are in the U.S.): Anglers can expect fair catches of hatchery and naturally-reproducing rainbows and kokanee. Trout to 14 inches and larger can be caught, with kokanee running 10 to 14 inches. This lake also offers some good largemouth and smallmouth bass fishing during the spring and summer, and good yellow perch fishing in winter. State park facilities are available.
