Ontario Hydro Network - Hydrographic Poly

A feature is a representation of a real world object, such as a lake, stream, dam or rapid.

There are three hydrographic feature classes:  points, lines and polys.   All may impede or be hazardous to waterflow and/or navigation on a watercourse or waterbody.

This data shows natural and manmade poly features.  Examples include:

  • break walls
  • dams
  • rapids
  • shipwrecks
