FortisBC and RDCK warn that high lake levels are expected over the next few weeks
May 20, 2022
Kelowna, B.C., May 20, 2022 ̶ FortisBC Inc (FortisBC) and the Regional District of Central Kootenay (RDCK) are notifying property owners along Kootenay Lake that due to above normal snowpack and delayed melt, there is an increased possibility that flooding could occur during late May or early June if temperatures rise substantially.
As of May 19, the lake level at Queen’s Bay was 1743.52 feet. It’s expected to rise two to three feet over the next week. Although lake levels are forecasted to remain below the 1752-feet flood level, the lake is subject to large natural inflows of water as a result of melting snowpack and precipitation. This means conditions could change suddenly over the next few weeks.
Power generation facilities like FortisBC’s Corra Linn Dam play a key role in managing lake levels. Since the beginning of March, FortisBC has discharged the maximum amount of water from Corra Linn. However, at this time, Grohman Narrows, a natural geological formation located upstream of FortisBC facilities, is restricting water flowing out of Kootenay Lake.
Residents and businesses along Kootenay Lake are encouraged to keep a close eye on lake levels over this period, assess what impact rising lake levels may have on their property and be prepared in the event there is a sudden rise in lake level. FortisBC provides daily updates on current and forecasted lake levels. For the most current information and to sign up for lake level notices, visit fortisbc.com/lakelevel.
Now is the time to be flood prepared. Residents should take the necessary steps to protect their home and property. Know the risks, have a plan and have an emergency kit.
