The Minnesota Department of Natural Resources has confirmed zebra mussels in McCarron Lake in Ramsey County.
A person trained in invasive species detection found six zebra mussels near the public access. A DNR survey found six additional zebra mussels north and south of the public access. In both cases, the zebra mussels were attached to rocks and muskgrass in 1 to 3 feet of water. Ramsey County staff conducted a targeted search and confirmed a lakewide zebra mussel presence.
Whether or not any invasive species has been confirmed in a lake or river, Minnesota law requires boaters and anglers to:
- Clean watercraft and trailers of aquatic plants and prohibited invasive species.
- Drain all water by removing drain plugs and keeping them out during transport.
- Dispose of unwanted bait in the trash.
Some invasive species are small and difficult to see at the access. To remove or kill them, take one or more of the following precautions before moving to another waterbody:
- Spray with high-pressure water.
- Rinse with very hot water (120 degrees for at least two minutes or 140 degrees for at least 10 seconds).
- Dry for at least five days.
People should contact an area DNR aquatic invasive species specialist if they think they have found an invasive species in a waterbody where it has not already been confirmed.

The Minnesota Department of Natural Resources invites the public to an open house to learn about updating the master plan for the David Dill-Arrowhead State Trail in St. Louis and Koochiching counties.
The open house will be from 6-8 p.m. on Sept. 4 at the Cook Community Center, 699 3rd Ave. S.E., Cook. The main parking lot and building entrance are along Gopher Avenue. Visitors to the open house can review information, ask questions and submit comments.
The David Dill-Arrowhead State Trail is about 125 miles long, stretching from an intersection with the David Dill-Taconite State Trail, just east of Tower, northwest to an intersection with the Blue Ox Trail, just south of International Falls. The current master plan was written in 1980 and revised in 1983. The trail is primarily managed for snowmobile use, but other uses such as hiking, biking, horseback riding and skiing are permitted in certain areas.
Written comments may also be submitted by emailing firstname.lastname@example.org, using the online comment form or sending via US mail to Joe Unger, DNR Parks and Trails, 500 Lafayette Road, St. Paul, MN, 55155. The DNR will accept written comments through Sept. 18.
