Navigation Branch 

The USACE Galveston District plays a key role in America's well-being by keeping waterways open for      navigation and commerce. The Galveston District is directly responsible for monitoring more than 1,000 miles of channel. Dredges are constantly at work keeping vital marine arteries open for waterborne traffic carrying cargo ranging from crude oil to coffee. Other priorities include construction of jetties or breakwaters to protect harbor and inlet entrances and the locks along the Gulf Intracoastal Waterway at the crossing of the Brazos and Colorado Rivers.
