Catalyst operates a weir which regulates water flow from Cowichan Lake into the Cowichan River for much of the year. The Cowichan River is the source of the water used at Crofton Division and of drinking water for local residents. Catalyst collaborates closely with regulatory authorities regarding weir operation, and it engages with local stakeholders on water management through its involvement with the Cowichan Watershed Board. Catalyst also contributed to and endorsed a comprehensive water management plan developed through a multi-stakeholder process.
