Protecting the Environment

Aquatic Invasive Plants and Animals

Zebra musselMichigan waters are threatened by non-native aquatic invasive plants and animals such as zebra mussels, round goby, sea lamprey, Eurasian ruffe, Eurasian watermilfoil, rusty crayfish, spiny water fleas, and hydrilla. These species and others are harmful to recreational boating and can cause extensive economic and natural resource damage.

Boaters should learn to identify non-native species that they may encounter and take precautions to prevent the spread of these species.

  • Remove all visible aquatic plants and animals from your boat, motor, trailer, and accessory equipment before leaving the access area.
  • Dispose of live bait and aquatic animals in the trash. Do not release live bait into the water.
  • Drain live wells and all water from boats before leaving the access area.
  • Power-wash boats and trailers wherever possible, or dry all equipment thoroughly.
  • Allow the boat to dry for at least 10 days before launching into a different body of water.
  • Fill out a Hydrilla Hunt I.D. card available online at the Michigan Sea Grant web page.

Please help support invasive species control, research, and education efforts by purchasing a Great Lakes Specialty Decal from the Michigan Electronic Store.

Waste-Handling Facilities

Waste pump-out stationMichigan has approximately 280 marina-provided pump-out stations that are widely available to recreational boaters. The 280 pump-outs serve 32,000 boats that have Marine Sanitation Devices (MSDs) and are kept at Great Lakes coastal locations in Michigan, including 9,000 boats not kept at marinas. Keeping our environment clean is everybody's job. Please make it yours.

Clean Boating Tips for Petroleum Control

Petroleum in or on the water is harmful and, in some cases, fatal to aquatic life. Floating petroleum reduces light penetration and the exchange of oxygen at the water's surface and contaminates the microlayer. The microlayer is the uppermost portion of the water column—home to thousands of species of plants, animals, and microbes that attract seabirds from above and fish from below. Pollution in the microlayer can poison much of the aquatic food web.

The Law

The Federal Water Pollution Control Act (also called the Clean Water Act) prohibits the discharge of oil or oily waste into or upon the navigable waters of the United States or the waters of the contiguous zone if such discharge causes a film or sheen upon, or discoloration of, the surface of the water or causes a sludge or emulsion beneath the surface of the water. Violators are subject to a penalty of $5,000 from the U.S. Coast Guard. State law also prohibits the discharge of oil. The Michigan Department of Environmental Quality may impose additional fines.

Fueling Practices

Gas or diesel may be spilled while fueling—as backsplash out the fuel intake or as overflow out the vent fitting. Spills harm aquatic life. Follow these tips to avoid problems.

  • Fill tanks to no more than 90% capacity—gas that is drawn from cool storage tanks will expand as it warms up.

Filling a fuel tank to the top can result in fuel spilling into the lake

  • To determine when the tank is 90% full, listen to the filler pipe, use a sounding stick, and be aware of your tank's volume.
  • Rather than filling your tank upon your return to port, wait and fill it just before leaving on your next trip. This practice will reduce spills due to thermal expansion because the fuel will be used before it warms up.
  • Fill portable tanks on shore where spills are less likely to occur and easier to clean up.
  • Use oil absorbent pads to catch all drips.
  • Slow down at the beginning and end of fueling.
