Cowichan LakeLake Level
A weir at Cowichan Lake stores water so that it is available for users downstream. Catalyst withdraws water from the Cowichan River for delivery to the Pulp and Paper Mill and the community of Crofton. Water is withdrawn about a kilometer upstream of the Allenby Road bridge in Duncan. Cowichan Lake is also the water supply for the Town of Lake Cowichan which withdraws water directly from the Lake. The Cowichan Lake level graph below shows the change in lake level over the course of 2023 (black line). the graph is updated as needed.
