Glenmore Dam infrastructure improvements

The Glenmore Dam will be under construction from spring 2017 until 2020. Upgrades include a new bridge deck with better access for pathway users, concrete work on the face of the dam and a new steel gate and hoist system.

Construction impacts

  • The public pathway across the Glenmore Dam bridge deck will be closed from September 30th, 2017 until project completion (estimated spring 2020). A detour is in place, as is signage.
  • Public parking will be restricted. Due to construction traffic parking will be temporarily eliminated north of 14 St. S.W.
  • Recreation opportunities will be impacted because the reservoir will be lowered to facilitate construction. Visit Calgary Recreation for details.
  • The construction area will be fenced off for safety with no public access to these areas. To accommodate construction vehicles, equipment and supplies.
  • Work will be performed from 7 a.m. until 7 p.m., Monday through Friday, and from 7 a.m. until 2 p.m. Saturdays. Periods of 24 hour activity are anticipated but are not expected to cause noise related issues.

Construction milestones

  • Demolition and removal of the existing bridge deck.
  • Removal of the existing wooden stop logs and demolition of the weir crest, on the overflow (spillway) section of the dam.
  • Drilling of rock anchor holes (to further reinforce the dam as a function of the new gate system).
  • Installation of platforms to accommodate work on the upstream face of the dam (concurrent with lowering of the reservoir).
  • Bird deterrent netting has been installed over the existing structure and daily inspections are performed to prevent birds from nesting on the structure. 
  • Site environmental inspections continue to be performed at regular intervals.
  • Installation of the crane/barge assembly on the reservoir.
  • Completion of the weir crest extension (to accommodate the new steel gate system), allowing the reservoir to be raised.
  • In the coming weeks, work will commence downstream of the dam (in the area known as the stilling basin) which will involve a fish relocation.

Why is the Glenmore Dam being improved?

Since the 1930’s the Glenmore Dam has been integral to Calgary’s water infrastructure system. An upgrade is needed due to the age of the dam.

What are the benefits of this project?

  • Continue to provide safe, clean drinking water for generations
  • Improve user access to the bridge deck with a wider, more pedestrian friendly pathway
  • Better views of the reservoir upstream and downstream
  • Extended lifespan of the concrete dam and bridge deck
  • Enhanced the appearance of the Glenmore Dam, an iconic structure and one of the City's oldest landmarks

What will the improvements look like?
