Parks Canada maintains the Ontario Waterways Water Management InfoNet on the Trent-Severn Waterway website.

The InfoNet contains background information on water management practices, water management updates, frequently asked questions about water management, various reports on water management, and the most recent water level of lakes along 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.

The Trent-Severn Waterway also maintains an email list for those wishing to have Water Management Updates sent directly to them via email.
