U.S. Army Corps of Engineers

– Section 10 of the Rivers and Harbors Act of 1899 (33 USC 403) empowers the Corps of Engineers (COE) to regulate all work on structures other than bridges or causeways that affect the course, condition, or capacity of navigable waters of the United States. This term includes those waters defined as navigable by the U.S. Coast Guard (USCG) but may also include rivers that were historically navigable or that with modification may be available for future use to transport interstate commerce. The determination of navigability will be made by each COE District engineer and is available upon request.
