Managing Water Levels

Public Works and Government Services Canada (PWGSC) is the federal department responsible for managing water levels within the standard operating curves for Lake Nipissing and the French River.

Water management is directed by long-established and widely-accepted operational guidelines, the Canadian Environmental Protection Act, the Navigable Waters Protection Act and the Fisheries Act. 

In addition, provincial flood rights and limits, and local building by-law restrictions are considered.  Historical weather and water level data are also important tools in the water management process.

  • Current and historical water level data is available from PWGSC.
