High Water Levels on Osoyoos Lake This Summer

June 30, 2017

Water Levels on Osoyoos Lake are expected to be higher than usual this summer.  This is due to high inflows into Osoyoos Lake from the Okanagan River. Osoyoos Lake will likely remain slightly above the normal summer-period high water level of 912 ft instead of the normal 911.5 ft summer operating level.  

Go the the Lake Level Status and Trends page for a more detailed update and to see the lake level in real-time (click here).
