Water Weeds:

  • Form dense growths that become navigation hazards
  • Impede recreational activities like swimming, fishing, boating, and waterskiing
  • Clog water intake systems of industries, municipalities and irrigators
  • Provide breeding habitat for mosquitoes and other pests
  • Divert water flows causing erosion and flooding
  • Become more difficult and expensive to control if ignored, early attention to developing problems reduces both the damage caused by weeds and the cost of controlling them.
  • Economic & Environmental Impacts of NC Aquatic Weed Infestations

Aquatic Weeds Found In North Carolina:

All noxious aquatic weeds recognized by NCDENR
