DNR targets half-acre of invasive algae on lake near Bemidji
Public access to a popular lake near Bemidji has been temporarily curtailed while the state attempts to remove a tenacious and annoying form of nonnative algae.
The Minnesota Department of Natural Resources (DNR) has temporarily closed public access to Turtle Lake while it conducts aggressive treatment on an expanse of starry stonewort that covers nearly three-fourths of an acre of the lake's surface.
Starry stonewort is a grasslike algae that can produce dense mats on the surface of a lake. They can choke out native plants, create a wall between fish and their spawning grounds, and interfere with boaters and anglers.
