Lake & River

Perfect Place to Boat and Paddle

Kootenay Lake is one of the largest lakes in British Columbia, and is perfect for sailing, kayaking, windsurfing, SUP (Stand Up Paddle), canoeing, leisurely boat rides and of course, fishing. Nearby rivers provide chill and casual floating experiences.

This massive lake is nestled between the Purcell and Selkirk Mountains, and is divided into three sections: North End, West Arm and South End.

  • North End runs from Lardeau to Balfour and is 64kms long, with remote beaches banked by deep evergreen and deciduous forests
  • West Arm runs from Balfour to Nelson and is 33kms long, winding alongside rugged cliffs, beaches and local residences
  • South End runs from Balfour to Kuskonook and is 63kms long, with an endless stream of beaches, on both sides of the arm

Kootenay Lake flows into Kootenay River, and at Castlegar into the Columbia River. The Columbia River Treaty, established in 1964 between Canada and the USA, coordinates flood control and optimizes hydroelectric energy production for both sides of the border. 

We are thankful to Friends of Kootenay Lake, a local organization focused on keeping Kootenay Lake pristine and clean for our future use, animals and vegetation. When exploring the region be safe where you play and reduce human-wildlife conflicts. Stay informed through WildSafeBC.

Marinas on Kootenay Lake

There are marinas all around Kootenay Lake of various offerings: boat rentals, fuel, boat repair and moorage. Kootenay Lake Sustainable Boating Society has a wealth of information showing marina listings, digital maps, pump outs and educational material. 


A boat cruise on Kootenay Lake is magical, with hidden coves and sandy beaches and vast open spaces. At times you'll feel like you're the only one on the lake. Jones Boys Boats, located at Woodbury, north of Balfour, has boating equipment and rentals. Kokanee Marina also has rentals throughout the summer. 


The local Kootenay Lake Sailing Association (KLSA) holds several annual sailing regattas each year, and offers friendly support to people learning to sail. Sailing on the lake is generally accepted to be relaxed and friendly. Sail Nelson also offers sailing tours and various courses. Gray Creek on the East Shore, at The Lakeview, hosts an annual fall regatta. Even if you don't sail, it is a spectacle of beauty and fun. 


Kootenay Lake offers the most amazing paddling experiences from wildlife to spectacular views. If you don't have your own gear, there are rentals in Kaslo, Nelson and near Balfour


Get up early and watch the sunrise on Kootenay Lake as you cast your rod into the depths of Kootenay Lake, or the shallows near one of the many rivers and tributaries. Fishing on Kootenay Lake is pretty dreamy, a getaway unlike any other. 


There are a number of marinas on the lake to put in your boat, refuel and even pumpout. Boat launches are abundant all along Kootenay Lake.
