Okanagan Lake is a large, deep lake in British Columbia, Canada’s Okanagan Valley. The lake is 135 kilometers (84 miles) long, 4 to 5 kilometers (2.5 to 3.1 miles) wide, and has a surface area of 348 km2.
Okanagan Lake is known as a fjord lake because it was carved out by repeated glaciations. Despite the lake’s numerous lacustrine terraces, it is not uncommon for the lake to be 100 meters deep only 10 meters offshore. Mission, Vernon, Trout, Penticton, Equesis, Kelowna, Peachland, and Powers Creeks are major inflows. The lake is drained by the Okanagan River, which flows from the lake’s south end to Skaha Lake via a canal that runs through Penticton.
The scenery across the lake, from beach to skyline, is part of Okanagan Mountain Provincial Park, which can be reached by boat or by driving back through Kelowna.
