Mariners are advised that due to low water levels on Lake St-Louis the speed limit between buoys A30 and A40 is reduced as follows:
* Vessels with a draft greater than 70 dm are limited to 10 knots upbound and 12 knots downbound.
* For vessels with a draft of 70 dm or less, the speed limit remains limited to 12 knots upbound and 14 knots downbound respectively.
The Administration of the Great Lakes St. Lawrence Seaway System will continue to monitor the water levels and advise of any other changes. Current details please see 2015 – Notice to Shipping #8 MAISONNEUVE REGION MONTRÉAL / LAKE ONTARIO SECTION.
