Ontario Hydro Network - Hydrographic Point

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 point features. Examples include:

  • waterfalls
  • rapids
  • rocks
  • Sea Lamprey barriers
  • shipwrecks

This product requires the use of geographic information system (GIS) software.
