Rivers and Harbors

The U.S. Army Corps of Engineers navigation mission is to provide safe, reliable, efficient, effective and environmentally sustainable waterborne transportation systems for movement of commerce, national security needs and recreation. Operations Branch supports the navigation mission through routine inspections of congressionally authorized civil works projects. Inspections generally include hydrographic surveys and aerial photography for navigation channels, ports and harbors. Inspections can periodically lead to dredging projects where sediments have moved into the project limits creating a hazard to navigation. Dredging projects occur annually at Anchorage, Dillingham, Homer, Ninilchik and Nome.

A current list of river and harbor projects is provided further below. Each project is divided into three dropdown sections. The Project Overview, Maps and Photos dropdown provides general information regarding surveys, inspections and maintenance as documented in the Project & Index (P&I) Book.  Although this book is updated annually, projects will only show the most recent activity performed, which could be many years ago.

The Hydrographic Survey dropdown includes condition surveys, which are generally a compilation of topographic and bathymetric data within the vicinity of the project. This data is represented by both contour lines and sounding points. Occasionally, the data will be shown as a color chart. This dropdown will display the last two to three condition surveys, including any pre- and post-maintenance dredging surveys that may have occurred within the last five years.

Finally, the Supplemental Data section may contain a variety of documents ranging from technical reports to presentations. Not all projects will contain information in this dropdown.
