Water levels in Cowichan Lake exceptionally high

With the water level in Cowichan Lake higher than it has been at this time of year for some time, Catalyst Crofton increased the flow rate at the weir on the Cowichan River to 10 cubic metres per second on Sept. 16. Brian Houle, the environmental manager for Catalyst Crofton which operates the weir that regulates the flow of water from the lake to the river, said the water levels in the lake are very close to the maximum that is allowed.

River Talk — Movement grows to build weir/dam across Koocanusa Reservoir

River Talk — Movement grows to build weir/dam across Koocanusa Reservoir

Completed in 1973, the Army Corps of Engineers dam was designed to regulate how spring snow melt in the Kootenay River watershed (87% of which originates in Canada) enters the downstream watershed. It has done so effectively, but at a considerable price to local residents. The upper end of the reservoir in Canada bears the brunt of the storage draw down each spring, and in dry years, the reservoir’s moonscape does not always refill to a level that allows for much recreation. The control over these water levels is 100% vested in American operation of Libby dam.
