Parks Canada's water management team continues to actively monitor water levels and flows, and weather forecasts across the Trent-Severn Waterway. These factors are used to determine dam operations on a daily basis for the waterway.

Water is managed on the Trent-Severn Waterway to permit safe navigation as well as the protection of fisheries, wildlife, municipal water supplies, recreation, and hydroelectric power. Our team works year-round to monitor and manage water levels across the system.

  • What is water management on the Trent-Severn Waterway?

    The Trent-Severn Waterway is an interconnected series of lakes, improved river channels and artificial canal cuts stretching for 386 km through the heart of Ontario. The water in the system comes from two major watersheds: Trent and Severn. The Trent River is the largest river in Southern Ontario while Lake Simcoe in the Severn watershed is the largest lake. The Waterway, including its tributary lakes and rivers, is an important economic, environmental and recreational resource used by thousands of boaters, shoreline residents, businesses and vacationers every year. It also provides water for power generation, municipal water supplies, and agriculture and supports a tremendous variety of fish and wildlife.

    The Trent-Severn Waterway is divided into four administrative areas, with offices in Campbellford, Lakefield, Kirkfield and Haliburton. Waterway Headquarters is in Peterborough.
