The Bayshore Floodgate is located at the junction of Waackaack and Thorns Creeks along the southern shore of the Raritan Bay. Constructed in 1973 as part of the U.S. Army Corps of Engineer's Beach Erosion Control and Hurricane Protection Project, the facility consists of a large floodgate and pump station at the base of the Raritan Bay as well as a series of levees and dikes that hold back floodwaters during large storm events.

The Bureau of Coastal Engineering has undertaken responsibility for the operation and maintenance of the facility on a 24-hour a day basis, protecting the communities of Keansburg, Hazlet and Middletown from coastal storms impacting the area.
