Ontario Hydro Network - Hydrographic Line

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 line features. Examples include:

  • break walls
  • dams
  • waterfalls
  • lock-gates
  • rapids
  • rocks
  • Sea Lamprey barriers
  • shipwrecks

This product requires the use of GIS software.
