City of Marquette recently issued the following announcement.
Effective Monday, Sept. 9, the Presque Isle Marina and Presque Isle boat launch will be closed for construction of the new docks. The marina will be closed until the completion of the project. The launch will be intermittently closed for demolition of the piers and installation of the new docks. The project is anticipated to be complete in early November 2019. During this time anyone wishing to launch on Lake Superior in Marquette should use the launch at the Cinder Pond Marina in the Lower Harbor.
This project is funded through a grant from the Michigan Department of Natural Resources Waterways Commission with a 50 percent City match.
