Details for Water Level Forecasts Bulletin (Current Bulletin)

Summary

Forecasts for the expected lowest water levels at the indicated stations in the St. Lawrence ship channel.

Description

1. These forecasts give the expected minimum water levels above chart datum at the indicated locations and at the specified times to assist commercial shipping in short term planning of operations (1 to 4 weeks).
2. This bulletin is produced by the Hydraulic Engineering sector, CCG, Headquaters on Thursday of each week.
3. The Canadian Coast Guard provides no guaranties on water levels and assumes no responsibilities relative to damages or losses resulting from the use of this information.
4. It should be clearly understood that this information is a forecast of water levels which may be altered by short term hydrometeorological factors. The vessel master or officer-in-charge has the ultimate responsibility for the vessel safety at all times.
5. The maritime industry has the responsibility of adding a sufficient safety margin to these forecasts. Hydrodynamic phenomena can influence water levels observed at gauging stations used by MCTS, especially during low water periods.
6. Ice jams management could induce important variations in the water levels. The water level forecasts within this bulletin do not take into account the potential variations resulting from ice jam management.
