The Ottawa River has over 50 major dams and 13 reservoirs. It is a highly regulated river. The dams were constructed either as a means of flood control, energy production, or to improve navigation.

A total of 43 hydroelectric generating stations and dams are located in the Ottawa River basin, and these are important for the two provinces’ economies. The generating stations are owned by Ontario Power Generation (a for profit company, formerly Ontario Hydro), or by Hydro Quebec, or by Public Works and Government Services Canada, and one is jointly owned and operated by Ontario Power Generation and Hydro Quebec (Chats Falls, 56 km northwest of Ottawa).
