Spring Floods - Preventive Measures




The Montreal Civil Security Center has lifted the state of emergency as of May 8th, 2019, however, considering the water level and the forecasts, the level of activation mode INTERVENTION 2 is maintained.

Weather forecasts predict heavy rainfall starting Friday morning which could leave 20 to 40 mm of rain in the watersheds of the Ottawa River. This precipitation could increase water flow of the Carillon Dam, which could increase water levels by 15 cm (6 inches).


Despite the decline in water levels of Lac des Deux-Montagnes over the past few days, significant variations in water levels may still occur. Therefore, it is essential to maintain the dikes and provide increased monitoring of their integrity.

Dikes will be dismantled when we reach RECOVERY mode, at which time the City will send out a newsletter. We ask all citizens to be remain patient and supportive.



The Chemin de l'Anse-à-l'Orme, between Senneville Road, Gouin Boulevard and North of Timberlea-Trail, remains closed in both directions until further notice following infrastructure security inspections.
