Client: City of Calgary
Location: Calgary, Alberta
Completion Date: 2003
Project Highlights:
The Glenmore Reservoir and associated structures are located on the Elbow River in the southwest quadrant of the City of Calgary. The structures requiring inspection and monitoring consist of the
Glenmore Dam, the Southeast Dyke and the Glenmore Causeway. The Glenmore Dam is a 320 m long concrete gravity structure with a maximum height measured from deck level to the bedrock foundation of approximately 30 m. The dam includes non-overflow sections, a pumphouse, spillway and stilling basin. The spillway has timber gates and a hoist. The hoist is a propane-powered hydraulic unit that travels along a track at deck level across all seven spillway openings.
The Southeast Earthfill Dyke was constructed across a low-lying area on the southeast perimeter of the reservoir. It has an approximate length of 914 m and a crest elevation of 1 079.9 m, giving it a maximum height of 6.7 m above original ground level. Subsequent to construction of the Glenmore Causeway the dyke was raised to an elevation of 1,081.3 m. As a result of concerns from residents of Bayshore Road SW, approximately 300 m of the dyke was lowered to elevation 1 080.5 m.
The Glenmore Causeway crosses the reservoir about half a mile upstream of Glenmore Dam. The Causeway was constructed across a narrow part of the reservoir in 1962 to improve traffic flow to southern Calgary. It consists of earthfill embankments with a waterway spanned by a 42.7 m long composite steel and concrete bridge for the passage of water. The lower part of the waterway slope is protected from erosion by heavy rock riprap; the upper part is protected by a concrete revetment. The stability of the rock riprap is enhanced by concrete infill.
