Cowichan Lake had just 16.5 per cent water storage capacity as of Aug. 13 as the recent hot spell, which saw temperatures in the region go above 30C, began to die down. Brian Houle, environment manager at the Domtar Crofton mill, which owns and operates the weir at Lake Cowichan, said the regulators of the watershed decided to reduce water flows from the lake over the weir to 4.5 cubic metres per second beginning on Aug. 13. He said the flow reduction will be done in two stages, dropping to 5.0 cms on Aug. 13 and then to 4.5 cms on Aug. 14 and that flow will hold until the rainfall returns this fall. …Houle said that, as water flows are reduced to the river, Domtar will have qualified professionals in the river helping to salvage fish stranded in pools, as well as measuring water quality.
