Located at the Lake Conroe Dam, the Lake Conroe Division’s primary functions include: Municipal and industrial raw water supply, reservoir operations, water quality and source water protection, invasive species management, navigational safety, and regulation of structures on the reservoir. Lake Conroe was constructed by SJRA beginning in 1969 and was completed in 1973 to serve as a water supply reservoir through a joint venture with the City of Houston, which owns two-thirds of the water rights in the reservoir.
