Maintenance and operation of the dam is one of the more important duties for Corps personnel at Long Branch. The integrity of the dam is maintained through regular inspections and maintenance activities. The Corps staff also regulates outflow through operation of gates within the dam outlet works.
The Corps operates a visitor center at the east end of the dam that is a source of information to the visiting public about local history, natural features and recreation opportunities. The visitor center is also the base of operation for a variety of interpretive programs conducted by Corps rangers for schools and organizations in surrounding communities.
