FortisBC generates hydroelectric power at four installations in the Kootenay Lake watershed. Vital to these operations is the level of Kootenay Lake, which is controlled by a network of dams and control structures that adjust the inflow and the outflow of water.
This control is required to support optimal power generation conditions, as well as water quality and quantity priorities, both for Kootenay Lake and downstream, in the Okanagan and Columbia River watersheds.
The Kootenay Lake level is governed by an order from the International Joint Commission (IJC). This bi-national body administers the Boundary Water Treaty of 1909, between Canada and the United States. The treaty provides the regulatory principles, and mechanism to prevent and resolve disputes concerning waters that flow along or across the border.
IJC Members (three appointed by each country, and assisted by advisors and staff in Ottawa and Washington DC) issue orders of approval, in response to applications for the use, diversion, or obstruction of these waters.
Among these, the Order for Storage in Kootenay Lake is of primary interest to FortisBC and its customers. It provides the parameters for the elevations of Kootenay Lake (as measured at a gauge installed at Queens Bay).
Kootenay Lake water levels fluctuate. When we anticipate a significant or rapid fluctuation of the lake level, FortisBC will make every effort to inform our customers, utilizing email and/or automated call-out technology.
