River Overview
The Kananaskis River originates in the Kananaskis Lakes basin within Peter Lougheed Provincial Park and flows northeast through the Bow Valley before joining the Bow River near Seebe. The river passes through a series of reservoirs and gorge sections, and flow volumes are significantly affected by releases from the Barrier Lake and Upper Kananaskis Lake dams operated by TransAlta.
Because dam releases can change flow conditions within hours, paddlers should check current discharge data from Environment and Climate Change Canada's Water Office before launching. Station 05BF024 (Kananaskis River at Seebe) provides near-real-time gauge data.
At a Glance
- Location: Bow Valley, Kananaskis Country, Alberta
- Total navigable length: Approximately 40 km (Barrier Lake to Seebe)
- Difficulty: Class I–III depending on section and flow
- Water temperature: Typically 4–12°C year-round — cold water protection required
- Best season: Late May through August; peak flows in June
- Mandatory portages: Two confirmed around dam infrastructure
Main Paddling Sections
Upper Section: Barrier Lake to Highway 1
Below the Barrier Lake dam, the river runs approximately 12 km to the Trans-Canada Highway crossing near Exshaw. This upper reach is largely flatwater and slow-moving riffles with some braided channels. It passes through a wide gravel floodplain with cottonwood stands and good wildlife habitat. Moose and elk are regularly observed along this stretch early in the morning.
There is a mandatory portage at the Barrier Lake dam itself — paddlers cannot run the dam infrastructure. Put-in is available at the day-use area downstream of the dam spillway. Take-out options exist at several pullouts along Highway 40 before it meets the Trans-Canada.
Middle Section: Highway 1 Corridor to Kananaskis Village Area
Between the Trans-Canada crossing and the Kananaskis Village area, the river presents a series of Class II riffles and short Class III drops during higher flows. This 15 km stretch is the most frequently paddled portion of the river. The gradient increases through a narrow canyon section where scouting is advisable at flows above 30 m³/s.
Access: Highway 1 rest area at Dead Man Flats provides limited parking and an accessible bank-side put-in. The Kananaskis Village area has a pull-off suitable for take-out and vehicle shuttle.
Lower Section: Kananaskis Village to Seebe
Below Kananaskis Village the river continues through Bow Valley Provincial Park before reaching the Seebe/Exshaw area and its confluence with the Bow River. This lower 13 km section includes a mandatory portage around the diversion weir near the Ghost Reservoir intake. The weir presents a serious hazard and must not be attempted — it creates a recirculating hydraulic across the full channel width.
Bow Valley Provincial Park has designated camping areas accessible by water, and this section is popular for multi-day overnight trips combining paddling with backcountry camping.

Portage Information
Two mandatory portages are confirmed on the standard river run:
- Barrier Lake Dam: Right bank portage approximately 200 m along a gravel track. The dam face drops 15+ metres and presents a fatal hazard. Current fencing and signage marks the portage clearly.
- Seebe Diversion Weir: Left bank portage of approximately 150 m. The weir spans the full river width and creates a consistent hydraulic. Visible from the water; approach slowly on river right to locate the portage trail.
Additional low-water portages may be required around log jams in the braided sections of the upper reach, particularly after spring ice-out or major flood events. Conditions change year to year.
Water Safety Requirements
The Kananaskis River is a cold-water environment regardless of air temperature. Water temperatures rarely exceed 12°C even in midsummer at lower elevations, and can be well below 5°C in spring. Cold water immersion incapacitates an unprotected swimmer within minutes.
| Equipment | Requirement |
|---|---|
| Personal Flotation Device (PFD) | Mandatory, worn at all times on moving water |
| Thermal protection | Wetsuit (minimum 3mm) or drysuit strongly recommended |
| Helmet | Required for Class II+ sections |
| Throw bag | Recommended for all moving water paddling |
| Communication device | Cell coverage is limited — a PLB or satellite messenger is advisable |
Seasonal Conditions
Spring runoff typically begins in late April and peaks in June depending on the year's snowpack. During peak flow, sections of the river that are Class II at normal levels can push into Class III+ conditions. The river is generally too low for comfortable paddling in late August and September unless dam releases are active.
Ice-out on the upper lakes typically completes by early May, and paddling season effectively runs from mid-May through mid-September. Fall paddling is possible but water temperatures drop rapidly after Labour Day.
Access and Permits
A Kananaskis Conservation Pass is required for all vehicles parked at day-use areas within Kananaskis Country (introduced 2021). The pass is available from Alberta Parks online or at self-serve kiosks at entry points. Camping within provincial park boundaries requires a campsite reservation through the Alberta Parks booking system.
No whitewater-specific permits are required for day paddling on the Kananaskis River itself, but paddlers operating within Peter Lougheed Provincial Park boundaries must comply with park regulations regarding portage and camping areas.
