When hydro-electric power was first delivered from No. 1 plan to Rossland's mines in 1898, the 32 mile transmission lines were the longest on the continent. Utilizing the 360-foot drop from Kootenay Lake to the Columbia River, later construction of the 5 dams and generating plants made possible the growth of Cominco operations at Trail and Kimberley.
