Dam Replacement at Kénogami, Québec
In July 1996 torrential rains caused widespread flooding in Central Québec. At the Kénogami Paper Mill, near Jonquière, an earthfill dam was washed away, emptying a reservoir which supplied the mill with process water and powered a 1.5-MW hydroelectric generating plant.
Hatch Energy accepted the challenge of replacing the dam in 4 monthsby the end of November. Conceptual and feasibility studies were completed in a week. A Hatch Energy team at Jonquière designed a one-of-a-kind replacement dam comprising rockfill shells with a granular core and a cement-bentonite cutoff wall, and a double rockfill groin cofferdam. Contractors were pre-qualified, documents prepared, and contracts awarded. Hatch Energy also supervised construction and managed the project on a fast-track basis.

The new dam was completed on schedule and within budget, and Hatch Energy went on to repair other facilities which had been damaged by the flood. This project was given an Award of Excellence by the Association of Consulting Engineers of Canada.
