Every summer, two Chelan County Public Utilities Division (Wenatchee, Washington) park maintenance workers use an Aquarius Systems weed harvester to cut and remove tons of Eurasian milfoil from parks and boat launches along the Columbia River. Without the PUD’s harvesting program, boat launches and swimming areas would be choked with weeds.
The benefit from the harvest is safety and convenience for users of parks along the Columbia River: no tangled feet and easier launching for boaters. The harvester cuts the milfoil below the water level, catches and lifts it onto a conveyor and secures it in a holding tank until the harvester docks and the milfoil is removed.
