Boaters in Thunder Bay have to take a detour if they want to launch their vessels. The City of Thunder Bay says the the launch facilities and the parking lot at Marina Park are closed to the general public during the construction. Only those who have paid to have their boats docked at the marina this year will have access to the launch. Alternate launch sites in the area include: The Current River Launch, the LRCA launches at Silver Harbour and Little Trout Bay Conservation Areas, the Nipigon Marina and the Red Rock Marina.
