Private Waterfronts

Owning a home on a lake is a dream for many families. Yet it can turn into a nightmare once the temperature warms up and yucky, invasive underwater species such as milfoil and lily pads emerge from their winter slumber to ruin swimming, tangle boat propellers and look terrible. 

Milfoil King, the Lake Defense Force’s waterfront restoration unit, can help. Our professional divers pull the dangerous weeds out at their roots, then truck them away. For a more permanent solution, we can install a “bottom barrier” that blocks the sun from rejuvenating stems. Contact us to join the hundreds of lake front property owners who proactively manage their underwater weeds.

Commercial Waterfronts

Marinas, waterfront apartment complexes, shoreline homeowners associations and private lakes face a proliferation of noxious, invasive, dangerous underwater weeds and algae. It’s easy for an individual homeowner to decide to remove infestations from their waterfronts, but it can be difficult for larger entities to reach consensus on a decision to fight back. 

Lake Defense Force has years of experience assisting corporate and HOA lake managers. We survey the property, forge elimination and prevention plans, and achieve consensus from all stakeholders in compliance with regulations. We specialize in milfoil, lily pads, elodea and curly pondweed removal; algae control; complete shoreline transformation; suction dredging and the construction of floating wetlands.

Public Waterfronts

Government entities ranging from small towns to large counties own thousands of lakes across North America. Civic managers are responsible for the health of and enjoyment of their lakes as well as beaches, kayak right of ways, boating channels, docks and wetland trails. 

Lake Defense Force helps agencies achieve their community goals by defining and executing on waterfront clean-up, maintenance and development objectives. We rely on years of experience with regulators to help agencies navigate the twisted path toward lawful weed abatement. Our goal is to help governments protect lake water quality and safety so that swimmers, boaters, fishermen and homeowners can all enjoy nature’s gifts.
