Water Management

Water levels and flows in the Trent-Severn watersheds are managed for public safety including mitigation of flooding; protection of the environment; fisheries; wildlife habitats; municipal water supplies; navigation; recreation and hydroelectricity generation. The Trent-Severn watersheds cover an area almost 4 times the size of Prince Edward Island with more than 120 water control structures and are managed by the staff of the Trent-Severn Waterway. The complexities of these multiple considerations require the application of integrated water management decision making by the staff of the Trent-Severn Waterway who monitor and manage water on a 24 hour basis continuously throughout the year.
