There is a lot of natural beauty to be seen in and around Castlegar, British Columbia, but there are many man-made marvels as well. And one of them is the Hugh Keenleyside Dam.

Located on the mighty Columbia River, 10 kilometres upstream from downtown, the Hugh Keenleyside Dam is 171 feet (52m) high and has a crest length of 2,800 feet (853m), made of earth and concrete. It was completed in 1968 as part of the Columbia River Treaty and controls a drainage area of a whopping 14,100 square miles, or 3.5 million hectares. The entire Arrow Lakes system extending 232 km north to Revelstoke is the dam’s storage reservoir and it should be said there is excellent boating and fishing in the area. (See our story about the largest Kokanee salmon on earth caught in Arrow Lakes.)

The best part of the Hugh Keenleyside Dam is it’s an easy drive to the lookout off Broadwater Road, on the other side of the river that provides visitors an excellent view of the dam’s super structure as well as informational signage about its history.

The Hugh Keenleyside Dam was one of the most controversial projects to have ever taken place in southern British Columbia. The valley extending to Revelstoke boasted excellent agricultural land as well as farms and villages and with the dam’s construction, about 2,000 people were displaced. It was originally known as the High Arrow Dam but was renamed in 1969 after Hugh Llewellyn Keenleyside, the co-chairman of BC Hydro, which owns the dam.

Visitors will also learn about the Columbia, the second largest North American river to drain into the Pacific (the Yukon River is the largest). It collects runoff from a basin slightly larger than the country of France and there are over 60 dams in its watershed, making it one of the most dammed rivers on earth. Eleven of those dams are within easy driving distance of Castlegar and it makes a fascinating day trip to visit some, or all, of them and learn about how the dams of the Columbia provide nearly half of British Columbia’s electricity. They’ve also completely reshaped the Kootenay region because catastrophic flooding, such as the one in 1948 when people died during a chaotic evacuation, no longer happens and communities have expanded into former flood plains. (For example, the Selkirk College campus in Castlegar would not exist were it not for the flood control provided by the dams.)

Here is a list of the dams on the Canadian side of the Columbia River that can be easily accessed by car from Castlegar. They are listed by proximity to the city.
