Indian River Quick Facts and Statistics


  • Indian River spans across 5 Florida East Coast counties: Brevard, Indian River, St. Lucie, Martin, and Palm Beach County. It is bounded on the west by the Florida mainland and on the east by a chain of beach barrier islands.


  • Indian River was formerly named Ais River, after the indigenous people inhabiting it's shores.



  • Indian River averages 4ft in depth with large shallow flats less than 2ft deep. Man-made channels, canals, and marina basins are dredged much deeper.


  • The Intracoastal Waterway, a national navigational channel through the entire Indian River estuary, is maintained at a 10-12ft depth.


  • In spite of its name, the Indian River is not an actual river with a directional current, but a still water lagoon where the water's movement is from wind and some minor tidal influence near the inlets.[1]
