If you're thinking about bringing your boat to a Minneapolis lake this weekend, you'll need to stop and get it inspected.
The city is stepping up efforts to stop the spread of zebra mussels and other invasive species.
The inspection started Friday at Lake Calhoun, Lake Harriet and Lake Nokomis.
Boaters seemed to be warming up to the idea, and some are even thanked inspectors for trying to keep the water clean.
Zebra mussels are a big concern because they multiply so quickly, taking over beaches and clogging boat entries.
Now, all boats – including sailboats and canoes – entering the lakes from the public boat launch must be inspected.
Inspection started at other Hennepin County lakes earlier this spring.
DNR officials are making sure boats are clean and dry, and live wells are empty.
Although the city of Minneapolis posted signs last year warning boaters about zebra mussels, the park board estimates only 1-in-5 boaters followed the rules.
Inspections at Lake Calhoun, Lake Harriet and Lake Nokomis will continue now until September 30. The public boat launches will be open from 6 a.m. to 10 a.m., and 5 p.m. to 9 p.m., Monday through Thursday.
Friday through Sunday, hours are extended from 6 a.m. to 9 p.m.
