Buoy Alert!

Image of a buoy with solar panels floating on a body of waterEpping/Springbrook Dam is now home to three LG Sonic algae control buoys. The buoys use ultrasound technology to reduce algae build-up in the lake. They are tethered to the bottom of the lake and will be in place spring through fall. The buoys also conduct continuous water quality monitoring so we can gain insights on the lake in real time.


How do they work? Ultrasonic waves block algae's access to sunlight and nutrients. Algae then sink to the bottom and die off without releasing toxins. Do they affect humans, fish or other wildlife? The low-power ultrasound integrated into the buoys is safe for fish, plants, people, pets, and zooplankton. The buoys are a chemical-free solution that does not disturb the natural balance of aquatic ecosystems. It only targets algae, improving water quality sustainably.

To report a problem with a buoy, please contact the Williams County Parks Director at 701-580-1628.
