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.
