The Kananaskis originates in the Canadian Rockies, east of the continental divide, in Peter Lougheed Provincial Park. It flows southeast to the Upper Kananaskis Lake, then turns north into the Lower Kananaskis Lake. From here it has a northbound course on the border of Spray Valley Provincial Park and Elbow-Sheep Wildland Provincial Park, where the Kananaskis Trail follows its itinerary. The lower course flows through Bow Valley Provincial Park, where Barrier Lake is formed along the river. Barrier Lake is an artificial lake used for hydroelectric power generation. The Kananaskis merges into the Bow River at Seebe, 30 km east of Canmore.
The Kananaskis River has a total length of 74 kilometers (46 mi).
Three dams, built in 1955, control the river's rate of flow: Interlakes, Pocaterra, and Barrier, all three of which are remotely controlled and operated by TransAlta.
Lower Kananaskis River Description
This section does not cite any sources. (December 2010) (Learn how and when to remove this template message)
For whitewater enthusiasts looking to run friendly class II(III) whitewater, the Lower Kananaskis is a very popular choice. As the river is dam-controlled, the water levels are predictable, and TransAlta generally posts the release times and flow rates on their website.
The Canoe Meadows site is home to the popular Kananaskis Whitewater Festival ("Kanfest"). This is an annual festival, typically occurring in mid-August, which attracts beginner and expert kayakers alike for a fun-filled weekend of kayaking-related activities.
The Upper Kananaskis (upstream of Barrier Lake) is not so paddler friendly: low water levels, lots of snags and sweepers.
- The put-in for the Lower Kananaskis is the parking lot for "Widow Maker" Rapid, located approximately 1 kilometre upstream of the Kananaskis Information Centre.
- The take-out for the Lower Kananaskis is Canoe Meadows Campground, approximately 1 kilometre downstream of the Kananaskis Information Centre
The first rapid on the Kananaskis is the Widow Maker, which is a class III pool drop that is notoriously tippy. It is easy to put in below the Widow Maker if the paddler is looking to avoid the feature. The first play feature is a small hole on river left called Hollywood. The river then winds down with man-made eddies on either side of the river to the second feature called point-break, which is considered the river's best hole for playboating. Downstream is the river's largest wave, called Santa Claus, with an aggressive hole 30 yards below it (dubbed "Santa's Little Helper"). The section finishes off with Canoe Meadows Campground on the right hand shore, with a large "V" wave popular with river surfers, a second wave called the Green Tongue, and a very developed slalom course. Nearly every rapid on this stretch of river was either created or manipulated by man-made boulder placements. The exit of the river to get back to the take-out is anywhere on the right hand shore after the last slalom gate. 
A major flood beginning on June 21, 2013 had a destructive effect on the man-made rapids on the lower Kananaskis River. Very few of them are still considered suitable for Playboating, partially due to movement of boulders, and partially due to inconsistent water levels. Soon after, the Alberta Whitewater Association reconstructed an interim slalom course, with plans to improve it further with additional time and funding.
