Dam creating the St. Mary's Reservoir
The St. Mary facility is located at the base of the St. Mary Dam near Magrath in southern Alberta. It uses water flowing from the low level riparian outlet located within the original diversion tunnel that flows into the St. Mary River. Water is withdrawn from the bottom of the reservoir and discharged into the diversion tunnel through a flow-regulating valve. The hydro facility takes all, or a portion, of this flow through a penstock (gate) installed inside the tunnel.
The facility can produce about 16,250 megawatt hours each year.
TransAlta owns and operates the St. Mary facility through its wholly owned subsidiary Canadian Hydro Developers.
