Kaslo
Duncan Dam, 42 kilometres (26 mi.) north, was the first of the three dams constructed by B.C. Hydro in accordance with the Columbia River Treaty, ratified by British Columbia and the United States in 1964. Southwest of the dam is the Kokanee Spawning Channel, built to compensate for the loss of natural spawning areas resulting from the dam's construction. The 3.2-kilometre (2-mi.) channel, one of the longest in the world, is said to be the first constructed for freshwater fish.
