Prevent surface water pollution
Petroleum spills from boats hurt lake water quality.
Avoid topping off your tank when refueling your boat
Ask your fuel dock to install automatic cutoff nozzles
Install a fuel/air separator to prevent accidental overflows from the tank vent line
Harmful bacteria such as fecal coliform can come from broken or grease-clogged sewer lines on land or from careless boaters.
Install a Type II Marine Sanitation Device (MSD) and empty it at an onshore pumping station
Keep your MSD properly maintained
Reduce the need to pump out your MSD by using onshore restroom facilities when possible
Litter from boats is not only ugly; it can harm wildlife.
Dumping garbage from boats is illegal
Install a garbage can on your boat
If you see litter in the water, pick it up and dispose of it properly onshore
