Okanagan Lake is called a fjord lake as it has been carved out by repeated glaciations. Although the lake contains numerous lacustrine terraces, it is not uncommon for the lake to be 100 m deep only 10 m offshore. Major inflows include Mission, Vernon, Trout, Penticton, Equesis, Kelowna, Peachland and Powers Creeks. The lake is drained by the Okanagan River, which exits the lake's south end via a canal through the city of Penticton to Skaha Lake, whence the river continues southwards into the rest of the South Okanagan and through Okanogan County, Washington to its confluence with the Columbia.
The lake's maximum depth is 232 metres (761 ft) near Grant Island (Nahun Weenox). There is one other island known as Rattlesnake Island, much farther south by Squally Point. Some areas of the lake have up to 750 metres (2,460 ft) of glacial and post-glacial sediment fill which were deposited during the Pleistocene Epoch.
Notable features of the Okanagan Valley include terraces which were formed due to the periodic lowering of the lake's predecessor, glacial Lake Penticton. These terraces are now used extensively for agriculture such as fruit cultivation.
Cities bordering the lake include Vernon in the north, Penticton in the south, and Kelowna, as well as the municipalities of Lake Country (north of Kelowna), West Kelowna (west of Kelowna), Peachland (south of West Kelowna), and Summerland (north-west of Penticton). Unincorporated communities include Naramata (north-east of Penticton).
The five-lane William R. Bennett Bridge, a floating bridge with a high boat passage arch connects Kelowna to the city of West Kelowna and the community of Westbank. This bridge replaced the three-lane floating Okanagan Lake Bridge on May 30, 2008, which had a lift span for passage of large boats.
Steamboats of Lake OkanaganEdit
During the early days of settlement and development of the Okanagan region, the lack of roads in the region made the lake a natural corridor for passenger travel and freight. The Canadian Pacific Railway Lake and River Service was the main carrier on the lakes, providing freight and passenger connections between Penticton, on the Kettle Valley Railway (the Southern Mainline) and Okanagan Landing (Vernon) for connections to the CPR Mainline at Sicamous via the Shuswap and Okanagan Railway. Smaller vessels such as the SS Naramata provided passenger service to smaller settlements around the lake, as well as excursions for tourists.
