River system data
Hydroelectric power is a clean, reliable, and low-cost way to produce the energy Ontario needs.
Ontario Power Generation (OPG) operates 66 hydroelectric stations and 239 dams on 24 river systems. These facilities help produce clean, reliable and low-cost electricity for Ontario.
This site provides information on water levels and flows at OPG hydroelectric facilities. Data is continuously collected using gauges that help safely manage OPG’s stations and dams in watersheds across the province.
