BC Hydro is notifying the public of changes to the discharge rates from Arrow Lakes Reservoir in order to undertake repairs to the guidewall at the Hugh L. Keenleyside Dam:
· At 12:30 p.m. today, Arrow flows were reduced from 1,784 cubic metres per second (63,000 cubic feet per second) to 1,642 cubic metres per second (58,000 cubic feet per second).
· Within the next hour, Arrow flows will be reduced from 1,642 cubic metres per second (58,000 cubic feet per second) to 1,501 cubic metres per second (53,000 cubic feet per second).
· If necessary, flows may be reduced to 1,359 cubic metres per second (48,000 cubic feet per second) by the end of the day.
When combined with the outflows from the Kootenay River, Columbia River levels at Birchbank are expected to see a decrease in water levels of about 0.52 – 0.76 metres (1.7 - 2.5 feet) from the current levels.
Please make safety your top priority when planning activities near the Columbia River.
