McGregor Dam

Vulcan, Alberta, Canada

McGregor Reservoir is an integral component of the Carseland-Bow River Headworks System that supplies water to 87,000 ha of agricultural land and numerous municipal, industrial and domestic users. The reservoir was created by the construction of the north and south dams in 1910 by the Southern Alberta Land Company, and significant upgrades to both dams were conducted in the 1950’s by PFRA. The reservoir has a live storage volume of 358M m3 and a flooded area of 5,300 ha. Releases from the reservoir are made through a low level outlet structure located at the south dam.

The work completed by Klohn Crippen Berger included completing engineering studies to assess dam upgrades, identifying spillway facilities required to safely handle the PMF, determining replacement options for the new low level outlet and abandonment options for the original structure, and evaluating the potential for hydropower development. Dam upgrades, construction of the new outlet structure, and abandonment of the original structure were completed in 2006.
