Every day thousands of vessels move people, animals, and products across the country via the nation's rivers and harbors. This water traffic is a vital component of the nation's economy. One of the Corps primary missions is to ensure that this traffic can move safely, reliably, and efficiently and with minimal impact on the environment.
The Corps primary navigation responsibilities include planning and constructing new navigation channels and locks and dams, and dredging to maintain channel depths at U.S. harbors and on inland waterways.
The Corps operates and maintains 25,000 miles of navigable channels and 196 commercial lock and dam sites and is responsible for ports and waterways in 41 states.
In partnership with local port authorities, Corps personnel oversee dredging and construction projects at hundreds of ports and harbors at an average annual cost of nearly $1.5 billion. The Corps dredges nearly 300 million cubic yards of material each year to keep the nation's waterways navigable. Much of this dredged material is reused for environmental restoration projects including the creation of wetlands.
Jacksonville District is responsible for 17 deep draft harbors and 20 shallow draft harbors in Florida and the Caribbean, as well as approximately 900 miles of navigable inland waterways. Seven of the ports are in the top 100 ports in the United States based on annual tonnage.
