Lessons on the Lake -> Chapter List -> Chapter 1 -> What is a Watershed?


  • A watershed is the total land area that contributes runoff to a specific body of water.
  • The runoff is the water which flows off the land surface.
  • The elevation and slope of the land determines which way the surface water will flow.
  • The lowest areas in the watershed that act as collecting basins include rivers, bayous, canals, ditches, streams and lakes.
