Most machinery and equipment, including gates and valves, are original to the facility. The annual closure gives dam safety experts and maintenance staff the chance to dry out the chambers for thorough inspections and to make necessary repairs. The routine maintenance is important to project safety and continued operation.

The U.S. Army Corps of Engineers owns and operates the Chittenden Locks. The busiest in the nation, nearly 40,000 vessels lock through each year.
