Ontario Dam Inventory

The Ontario Dam Inventory (ODI) is an inventory of medium and large dams throughout Ontario. It uses a point-based system (x, y location) to identify each dam location. The ODI does not contain:

  • small dams
  • small water control structures
  • beaver dams
  • water crossings
  • road embankments
  • locks
  • falls
  • rapids
  • culverts

Each dam location has an identifier that can be used to link to other dam information databases.
