It's the Law: Protecting the Environment

Aquatic Invasive Plants and Animals

South Dakota waters are threatened by non-native aquatic invasive plants and animals such as zebra mussels, Eurasian watermilfoil, and purple loosestrife. These species and others are harmful to recreational boating and can cause extensive economic and natural resource damage. Many invasive plants grow rapidly in our lakes. The dense mats of vegetation they form can restrict or prevent boating and fishing and may make the waterway entirely impassable.

• Boaters should learn to identify nonnative species and take precautions to prevent the spread of these species.
• These actions include:
  • Removing all visible aquatic plants and animals from your boat, motor, trailer, and accessory equipment before leaving the access area.
  • Disposing of live bait and aquatic animals in the trash. Do not release live bait into the water.
  • Draining live wells and all water from boats before leaving the access area.
  • Power washing boats and trailers wherever possible or drying all equipment thoroughly.
  • Allowing your boat to dry for at least 10 days before launching into a different body of water.
