Last October marked 50 years of service for the Hugh L. Keenleyside Dam in Castlegar. Originally named High Arrow Dam, it was renamed in 1968 after Hugh Llewellyn Keenleyside. Dr. H.L. Keenleyside became co-chair of BC Hydro when it was formed from the British Columbia Power Commission and BC Electric in 1962.
High Arrow (later named Hugh L. Keenleyside) Dam during construction in 1967. The dam is the second of three built by BC Hydro under the terms of the Columbia River Treaty. At the peak of the project in the winter of 1966-67, over 1,600 people were working to build the dam.
The dam is about 52 metres high, with a crest length of 853.4 metres. Of this, 366 metres of the crest length is concrete dam and the rest is earth fill dam. The completed dam structure required a total of 583,000 cubic yards of concrete, 2.3 million bags of cement, 5,250 tons of concrete aggregate and 7,500 tons of structural steel.
