Mactaquac Dam, Fredericton

(1/5 based on 35+ reviews on the web)
The Mactaquac Dam is an embankment dam used to generate hydroelectricity in Mactaquac, New Brunswick. It dams the waters of the Saint John River and is operated by NB Power with a capacity to generate 670 megawatts of electricity from 6 turbines; this represents 20 percent of New Brunswick's power demand.LocationFormally called the Mactaquac Generating Station, the dam and power house are located approximately 19km upstream from the city of Fredericton. The dam is an embankment dam consisting of a rock-fill structure sealed by clay. It combines with two concrete spill-ways to form an arch across a narrow section of the river between the communities of Kingsclear on the west bank, and Keswick Ridge on the east bank.ConstructionRising 40 metres in height above the river level, the reservoir covers 87 square kilometres and extends 96 kilometres upstream, near Woodstock. The dam and powerhouse are a "run of the river" design, meaning that the reservoir has no additional holding capacity in the event of unusually high water flows, such as during the spring freshet.Kingsclear, NB is also the site of an Atlantic Salmon fish hatchery, located immediately downstream from the dam. The Mactaquac Dam also has a fishway to catch salmon and transport them upriver.

  • Not to far off the transcanada highway. A quieter approach to Fredericton. Engineering interest. Nice rural area or suburb of Fredericton.  more »
  • As an attraction there is not much to see for walkers as there are no walking paths on th bridge itself but driving over the bridge is nice to do to the water cascading below the dam level into St. Jo...  more »
  • A nice leisurely drive from Fredericton or go through Keswick Ridge. Either way, the scenery is beautiful. Campground not far from the dam.  more »
