Conditions on the Trent-Severn Waterway. Trenton → Georgian Bay, km 0–386.
Open water first: strong wind warning on Lake Simcoe; strong wind warning on Georgian Bay; strong wind warning on Georgian Bay. If your day involves the crossing, check the marine forecast below before you commit to it.
Crowe River is the low spot on the system today at -19 cm (-7.6 in) against its usual level for this month. Burnt River is also running low. That doesn’t move the chart — it moves what’s under your keel.
All 40 locks and 12 bridges are showing operable on the Parks Canada feed.
Season’s end. Confirm lock hours before you move; the system drains down after closing.

Water levels
Each gauge is compared against its own historical average for this month. The deviation is the number that matters — gauge datum is not chart datum, so the reading itself won’t tell you a depth, but the change from normal tells you how today compares to a typical day this time of year.
