Energy, Survey & Planning
  • Different watershed zones represented by different colours
  • Any water that falls into a zone will stay within the zone and only flow out thru the outflow points (coloured lines)
  • Water will not flow out thru any other point, and will not cross boundaries of watershed
  • Light shades represent higher elevation and dark shades represent lower elevation
  • Note how boundaries of watershed roughly correspond to higher elevations
