A new video from an IJC flooding study shows how water flows in and out of Lake Champlain and how wind, waves and rain can affect water levels in the lake, the Richelieu River and its tributaries.
Lake Champlain runs for about 193 kilometers (120 miles) through Vermont, New York and Quebec. Surrounded by mountains, the watershed sits mainly in the United States; 16 percent rests in Canada.
The water flows northward, and as Lake Champlain narrows near Rouses Point, New York, it becomes the Richelieu River. The river flows across relatively flat terrain for 125 kilometers (78 miles) before emptying into the St. Lawrence River in the city of Sorel-Tracy, Quebec.
The video illustrates the flow of water through the basin, and describes factors that can cause fluctuations in water levels. It also looks at how Canadian and US residents were impacted by flooding that occurred in 2011 and damaged homes, properties and shorelines.
The video was introduced at the last set of public meetings of the International Lake Champlain–Richelieu River Study Board in November 2018.
Begun in 2017, the five-year study will propose measures to reduce the impacts of flooding, as well as tools for flood forecasting and preparedness. Visit the study online to learn more and subscribe to updates.
