Stop Aquatic Invasives!

Help stop the spread of invasive aquatic species to Chautauqua Lake! 

An invasive species is a plant, animal or other organism that is not native to an ecosystem and whose introduction to that ecosystem can threaten the biodiversity of, functions of and human use of the new ecosystem.  They can also adversely affect human health and local economies.  Once an invasive species has established itself in a new ecosystem, it is extremely difficult to control its spread.  Aquatic invasive species are commonly spread via recreational boats and other recreational equipment that has been transported among various bodies of water. 

You can help prevent the introduction of invasive species to Chautauqua Lake and other area waterways by not transporting water, plants or animals from one body of water to another.  Each time you leave a body of water, be sure that you:

  • DRAIN water from all equipment (boats, motors, trailers, bilges, live wells, bait containers, etc.)
  • REMOVE any mud or plant/animal material from all equipment, including fishing poles/tackles
  • DISCARD any removed materials in a trash receptacle away from the lake or other waterway
  • DISPOSE of unused/unwanted bait in a trash receptacle away from the lake or other waterway
  • RINSE boats and other equipment with tap water (preferably hot and/or high pressure) or
  • DRY for at least 5 days before using in another body of water
  • DO NOT RELEASE OR DUMP plants, fish/bait, animals or water into a body of water unless they originally came out of that body of water

The early identification and removal of invasive aquatic plant species can also help keep them from spreading.  In the summer of 2012, the invasive water chestnut plant (pictured at left) was discovered in Chautauqua Lake and, in 2014, at the Chautauqua Lake Outlet.  IF YOU SEE THIS PLANT, DO NOT REMOVE IT!  Instead, call the Jamestown Audubon Society at 716-569-2345 to report it and have an expert remove it.  If you are interested in becoming a volunteer for "search and destroy" efforts of this plant in western New York and Pennsylvania, contact Jean at the Warren County Conservation District at 814-726-1441.  For more information on the water chestnut, visit
