When Arnprior GS was built, engineers had to address the change in water elevation. The solution was to construct a weir (an artificial waterfall), which helped to control water levels between the Madawaska and Ottawa rivers. The weir, much like the station, is a part of the town’s landscape. While a prominent feature, the weir can be dangerous and people should not attempt to get close. Warning signs, fencing and a large yellow safety boom are in place for the public’s protection. To learn about OPG’s water safety program, please visit www.opg.com/watersafety
As with the operations at all of our generating stations, OPG is considerate of the environment and other users of the waterways. Our technicians manage water levels and flows according to the approved Madawaska River Water Management Plan
. The amount of water available for generation depends on environmental needs, minimum and maximum water level requirements, and precipitation.
Arnprior GS generates clean, renewable electricity 24 hours a day, 365 days a year, and is part of OPG’s clean energy portfolio which is more than 99 per cent free of greenhouse gas and smog emissions.
