Maine Navigation Projects

The Corps has completed 66 navigation projects in Maine. These projects have improved rivers, bays, coves, and harbors that are used by commercial interests, fishermen, and the many recreational boaters that benefit from the intricate and fascinating Maine coastline. Initial work on many of the projects dates back to the early 19th century. However, much of the navigational work in today's waterways has been constructed by the Corps within the past 50 years, costing an aggregate $29.7 million. Below are the Corps' navigation projects in Maine.
