Osoyoos Lake is an International Lake and has no restrictions regarding Ski Boats or Jet Skis, unless you cross the border. Contact Canada Immigration or the US customs for the proper paper work and directions for crossing the border in a boat! Osoyoos Lake is 5,723 acres, 2,036 of which are in the U.S. The deepest point of the lake sits at 65' deep making it one of the shallower lakes in the region. The maximum level of the lake is 912.78' in elevation, but fluctuates in the fall/winter down to 909.46'. The normal low water elevation of Osoyoos Lake is maintained by the Zosel Dam at Oroville, Washington. Anglers can expect good 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 as well as cat fish. There is a boat Launch at Deep bay Park and it is just around the corner from this property.
