Aquatic Invasive Species Checks Increase

Pierre, S.D. -The South Dakota Game, Fish and Parks (GFP) will conduct aquatic invasive species (AIS) rule compliance checks along the Missouri River in central South Dakota this weekend.

Statewide regulations changed last year in response to the discovery of zebra mussels, a small, invasive mollusk in Lewis and Clark Reservoir. Most recently, mussels were also discovered in McCook Lake. The small, clam-like creatures spread quickly and can damage beaches, boat motors, irrigation systems and other infrastructure. Juvenile mussels are the diameter of a human hair and can live for days in even a small amount of water remaining in a boat or jet ski; making it possible for boaters to unknowingly transport mussels to new waters.

Except when being loaded, launched, on the water, or when traveling to a fish cleaning station immediately adjacent to the ramp used to launch a boat, all drain plugs, valves or similar devices must be removed or open. Plugs and valves must be removed or open before leaving an adjacent fish cleaning station and all plugs must be removed and valves must be open when a boat is in transit or storage.

"Compliance with these regulations is a key factor to ensure the best possible future for the state’s fisheries and water recreational resources," said GFP regional conservation officer program manager, Dale Gates.

If a boat is inspected and found to be in violation of the law, the boat owner will be subject to a Class 2 misdemeanor and an $85 fine.
