A flood occurs when an shoreline area is submerged because the volume of the body of water has surpassed the capacity of its bed. Major floods usually happen when snow melts in the springtime, during periods of heavy rain, but also in wintertime when frazil accumulates (see Types of Floods). A quick and major increase of the water level can also occur when a dam breaks.

Booklet

Senneville is a municipality nestled by the Lac des Deux-Montagnes. As such, floods and Frazil Ice are one of the main natural hazards occurring on the territory.  

During the year, flood forecasters monitor the amount of rainfall and snow and the impact on levels on rivers, lakes, creeks and streams.

Due to risk of flooding, several bodies of water are subject to continuous monitoring.

A body of water is flooded when its last measurement is above its minimum flood threshold (SIM). Click below to view the chart or hydrograph.
