WHAT YOU CAN DO....
Boat wake increases shoreline erosion and disturbs nesting loons, mallards, etc.
Observe the 8 km/hr. speed limit, it applies to the entire lake

Observe the loons from a distance: the tremolo or laughing call is a distress call that loons give when alarmed or threatened. You have approached too closely
Maintain your boat motor to reduce emissions and noise
