BC Hydro is planning to increase the amount of water discharged through the Keenleyside Dam to help bring down the water level in the Arrow reservoir.
The total flow through the dam is expected to reach 165,000 cubic feet per second — 20,000 cfs more than usual — by Saturday and continue at that rate for several weeks.
It will be the highest Columbia River flow in over a decade.
BC Hydo, in a press release, urged residents to be mindful of higher than normal flows when planning activities near the Columbia and Kootenay Rivers
“Like all rivers with upstream hydro-electric facilities, river flows can change suddenly,” the release said.
