Arrow Lakes Reservoir


In the valley between the Monashee and Selkirk mountain ranges is the Arrow Lakes reservoir. A great waterway for boating, it runs 230 kilometres from near Revelstoke in the north, to Castlegar in the south. The reservoir was created when the Hugh Keenleyside Dam was constructed to bound the original Arrow Lakes and the Columbia River.

There are three ferry crossings across the reservoir. At the north end, between Galena Bay and Shelter Bay, between Needles and Fauqier, and in the south between West and East Arrow Park.

Water levels

Three daily elevation gauges are available for the Arrow Lakes Reservoir: Nakusp, Fauquier, and Hugh Keenleyside Dam (Arrow Dam Forebay). Check daily reservoir elevations.

The Arrow Lakes Reservoir elevation at Fauquier is also available by calling 1 877 924 2444 from anywhere in North America. The toll free line is updated every Monday, Wednesday and Friday, except holidays.

Weekly reservoir updates are available via email for the upper and lower Columbia with short-term reservoir level forecasts. To subscribe, please send us an email.

Columbia operations summaries explaining the Columbia River Treaty and other agreements, system and facility operations, and reservoir water level information are distributed bi-annually. To subscribe, please send us an email.

Regional annual reports are distributed every fall to local government, the media and stakeholders. These reports are available in the Your Region section.

Boating safety

Reservoir operations combined with the topography of the reservoir create hazards that are unique to man-made water bodies.

Water levels within the reservoir fluctuate by as much as 20 metres annually and are constantly changing due to inflow and the requirements for water release at Hugh Keenleyside Dam. Reservoir levels can rise or fall by approximately 30 cm in a 24-hour period at any time of the year.

Boaters are cautioned that when the reservoir is not at its maximum level, bars, rocks or debris, including stumps, may lie just below the surface. Boaters should also be aware of strong winds that occur suddenly, causing high waves and strong currents.

Please exercise caution when anchoring larger boats near the shoreline in shallower water; a drop in the reservoir level could leave you high and dry. Generally, water levels will tend to drop in the fall and winter, and rise during the spring and early summer.

Boaters using the reservoir in late summer, fall and winter should be particularly alert to the risk of being stranded by decreasing water levels.

The area south of Revelstoke is critical. The original channel cuts through a wide, flat river bottom for 48 km south of Revelstoke. The area on both sides of the channel is covered by only 0.6 to 1.8 metres of water, even when the reservoir is at its highest.

Boaters are cautioned to keep to deep water in this area. Slow down, and watch for shoals and log bundles. Don’t leave your boat unattended in this area.

Dam intakes at the Hugh Keenleyside Dam, and outlets from the Revelstoke Dam, can cause strong surface and underwater currents. For your own safety and the safety of others, obey all posted signs and remain well away from BC Hydro dams and operating structures.

Sudden releases of water may occur downstream from Revelstoke Dam. Discharged water levels may be high and extremely dangerous for boaters in the immediate area.

While BC Hydro does not allow debris to pass through its dams, boaters should always be alert for floating debris, submerged debris and shoals at different reservoir levels.

If you are intending to operate a boat on Arrow Lakes Reservoir, always:

  • Obey all boater safety laws
  • Don't drink and drive/boat
  • Ensure that you have an accurate map
  • Carry emergency and safety equipment, extra shear pins and a propeller
  • Ensure familiarity with any marked channel and reservoir hazards
  • Inform others of your destination and when you are to return
  • Check the weather
  • Know where the nearest safe moorage/anchorage or beach is at all times

Also refer to the Transport Canada's Safe Boaters Guide.

Safe anchorage

In addition to amenities generally found at or near communities, boaters can find refuge or sheltered anchorage at various locations around the reservoir. Accessibility and the degree of protection at each location varies depending on the time of year, reservoir level, direction of prevailing wind and general weather conditions.

At some locations, small craft can be beached, but boaters are reminded to: be careful with open fires; remove their litter, and; respect private upland property.

Hugh Keenleyside Dam navigational lock

The Hugh Keenleyside Dam navigational lock is available for all properly equipped watercraft. There is no charge for use of the lock; however, weekday passage may be delayed because of the need to pass commercial traffic and logs downstream of the dam. Commercial traffic will have priority in all cases over pleasure craft.

The lock is in operation on weekdays from 6:00 a.m. to 4:00 p.m. and on weekends from 8:00 a.m. to 4:00 p.m. The lockkeeper is available at 250 365 3115.

Recreation opportunities and boater services

A number of recreation areas and facilities are located along the shoreline of Arrow Lakes Reservoir. These are managed by BC Parks, Ministry of Forests or the local municipal government. They are: Syringa Creek Provincial Park, Blanket Creek Provincial Park, McDonald Creek Provincial Park, Shelter Bay Provincial Park, Edgewood Park, Fauquier Park, Burton Historical Park, Taite Creek Recreation Site, Octopus Creek Recreation Site, Sunshine Bay Recreation Site, Bowman Point Recreation Site, Begbie Falls Recreation Site, Akolkolex Falls Recreation Site, Eagle Bay Recreation Site, Nakusp Recreation Area, and Centennial Park (Revelstoke). Some Ministry of Forests recreation sites are fully maintained with user fees, while others are user-maintained with no fees.

Boat fuel is available at Syringa Marina, Scotties Marina, Edgewood, Needles and the Village of Nakusp. Boat launching facilities exist at Syringa Park Marina, Scotties Marina, Syringa Creek Provincial Park, McDonald Creek, Shelter Bay, Edgewood Park, Fauquier Park, Burton Historical Park, Eagle Bay, Nakusp and Centennial Park. However, some facilities are not useable or accessible when the Arrow Lakes Reservoir reaches low elevations.
