Some products advertising the ability to "blast away" mucky lake bottom without a permit could get homeowners ticketed, according to the Minnesota Department of Natural Resources.
The DNR says some products that create water currents to push away plants and debris from docks and shoreline shouldn't be used to excavate the bottom of a lake or river.
"Property owners need to be aware that use of these and similar products could expose them to a citation," Steve Ender, a DNR aquatic plant management supervisor, said.
Products can look like a fan or trolling motor contained in a short tube. They operate by creating strong currents of moving water. The DNR says they are not always legal. However, if the product is moving sediment, it's probably not allowed.
“When directed at a lake bottom these products can uproot aquatic plants and cause plumes or clouds of disturbed sediment to drift down the shoreline, interfering with other people’s enjoyment of the lake and possibly covering spawning areas with a layer of sediment,” Enger said.
Consumers should use caution when considering any plant removal. Aquatic plants are important to lakes because they help maintain water clarity, prevent erosion and provide habitat for fish and wildlife.
