Lake Okanagan sits at 344 meters above Sea Level and is part of the Okanagan Valley land basin. The lake has three cities on it's shores with Vernon at the North end, Kelowna on the Eastern  shores in the central region and Penticton at the South end. Hyrdographic charts show the lake to be 232 meters at it deepest. The lake is fed by snow melts from the surrounding mountain ranges that border it's shores with the largest source being Mission Creek which enters the lake in Kelowna.

The water of the lake is used for many purposes and it's quality is monitored by both government and local agencies including First Nations.

Over the years divers have participated in many lake clean-up events along the waterfront.

Historically the lake has frozen over, but today we only see some ice formation along the shore. Lake temperaure vary with the coldest water in late December thru to the end of April. The water is very warm during the summer months and the lake is used for all types of watersport activities. There are many rock faces and dropoffs particularly along the shore of Okanagan Park Provincial Park, located on the East side of the lake and across from Westbank and Peachland.

Visibilty ranges from 35 feet plus in the winter to 15 feet or less in the summer. There are many species of fish in the lake from land locked Kookanee Salmon to Trout, Carp, Cod and the extremely rare Pumpkinseed. The Pumpkinseed is endanged and the closest you will ever get to seeing a tropical fish is cold lake water. There are stories of Sturgeon in the lake along and it is well know for Ogopogo, a creature that has been sighted from since the beginning of recorded history in the area to present day.

There is very little current in the lake other than Ceasar's landing located North of Kelowna on Westside Road.

Divers have been active in the lake for years and have made some efforts to populate the lake with underwater artifacts. In Ellison Provincial Park located West of Vernon you'll find a collection of boats. In Okanagan Centre, you'll see a varity of objects and North of Penticton on the West side of the lake is a small Provincial Park with a couple of boats.

There are many historical artifacts in the lake. You should know that British Columbia has one of North America's strongest Archaeological Site Protection Acts. If you do dive on any of these sites, it's important that the site and anything on it be left the way you found it.
