PETERBOROUGH, ON – June 4, 2025 - Parks Canada announces that conditions are favourable to allow for the re-opening of the entire Trent-Severn Waterway National Historic Site for daytime navigation starting at approximately 1 p.m. on Friday, June 6. Opening times may vary lockstation to lockstation depending on water management, operational requirements, and precipitation.

Over the past couple of weeks, the Trent-Severn’s watersheds have received significant amounts of precipitation, prompting Parks Canada to close multiple lockstations in the interest of public safety. On May 24, Lock 1 in Trenton through to Lock 18 in Hastings were closed, followed by Lock 22 to 27 from Nassau Mills to Burleigh Falls on May 28.

For residents and boaters along the Trent-Severn Waterway, flows will continue to increase outside of navigation hours until further notice. The public should consider these overnight flows as non-navigable. The increased flows overnight are the result of water management dam adjustments to address higher-than-normal water levels caused by recent precipitation. Due to these adjustments and anticipated precipitation, fluctuations in water levels are expected.

While water levels and flows are on the decline, residents and visitors should continue to exercise extreme caution both on and around the water. All boaters are strongly encouraged to lower their speed to limit their wash and wake.
