The Corps has completed 10 navigation projects in New Hampshire that have improved rivers, harbors, and lakes used by commercial interests, fishermen, and the many recreational boaters that benefit from New Hampshire's coastal and inland waterways.
Initial work on some of the projects dates back to the 19th century. However, most of the navigational work in today's rivers and harbors has been constructed by the Corps within the past 50 years, costing an aggregate $6.65 million. (More information on the navigational role of the Corps is available).
The following pages describe the Corps' navigation projects in New Hampshire. Depths given for channels and anchorages are those at mean low water.
