A pair of local boat launches will be closed this Saturday for the launch of Marinette Marine’s LCS 17. Boom Landing in Marinette and River Park ramp will both be closed from midnight on Friday until approximately 5:00 PM Saturday evening. During this time, all boats, including kayaks and canoes, are prohibited from entering the marine safety zone which spans from Nestegg Marine downriver to the east end of the KK Integrated Logistics’ dock wall. Boaters on and around the Menominee River are advised to use caution and pay attention to directions from law enforcement and Coast Guard personnel Saturday.
