River Conditions Forecast

The warm spell and rainfall of February 19 to 21 in the southern and eastern parts of the basin will cause water levels and flows on the main stem of the Ottawa River between Lac Coulonge and the Montreal region to increase gradually in the next few days. With forecast cooler temperature starting Thursday and no additional significant precipitation, levels and flows are expected to stabilize into next week.
