PETERBOROUGH, ON – May 24, 2025 – Due to high water levels and flows, Parks Canada will begin a partial closure of navigation starting this Monday, May 26, 2025, until further notice in the interest of public safety.

Over the past 7 days the Trent-Severn’s watersheds have received significant amounts of precipitation and is forecasted to receive more in the coming days, bringing water levels well above normal navigational levels. Residents and visitors should exercise extreme caution around and on the water.

As of Monday, May 26, 2025, Lock 1 - Trenton through to Lock 18 – Hastings will be closed to navigation. This section of the Trent-Severn Waterway National Historic Site may be closed earlier if all moving vessels have safely exited this part of the system.

As of Saturday, May 24, 2025, residents and boaters from Young’s Point to Peterborough, and from Lake Simcoe to Georgian Bay can expect increased flows outside of navigation hours until further notice. The increased flows overnight are the result of water management dam adjustments to address the higher-than-normal water levels caused by the recent precipitation. The public should consider these overnight flows as non-navigable.

This partial closure will protect boater safety and help to prevent shoreline erosion and property damage experienced by local residents and businesses. All boaters are strongly encouraged to lower their speeds and watch their wake.

Parks Canada will continue to work diligently to re-open the entire system for navigation as soon as it safe to do so. Updates will be provided regularly and communicated widely.
