Morrison Dam

Coronach, Saskatchewan, Canada

Morrison Dam is an 1830 m-long, 17 m-high earthfill dam situated on the East Poplar River approximately four km north of the Canada – USA border. The dam creates Cookson Reservoir which stores about 41,000 m3 of water and has a surface area of 680 ha at its full supply level. The reservoir primarily provides cooling water to the adjacent Poplar River thermal power plant. A service spillway, equipped with radial gates, and an auxiliary spillway channel have been provided to handle floods up to the probable maximum flood. In addition, a low level outlet structure is used to provide riparian and apportionment flows. The facilities were constructed in 1976, and are owned and operated by SaskPower.

Klohn Crippen Berger was the prime consultant responsible for performing the annual inspection of the dam, structures and instrumentation, and completing the performance evaluation of the seepage monitoring system.
