Mariners are advised that due to low precipitation, and declining outflows, the water levels on Lake St-Louis are lower than normal. For this reason, the speed limit between buoys A30 and A40 is reduced as follows:
Vessels with a draft greater than 70 dm are limited to 11 knots upbound and 13 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 authorities will continue to monitor the water levels and advise you of any other
changes.
