water patrol station
A base for police or security personnel who patrol harbors, waterways, lakes, or open water, usually by boat.
A water patrol station is a base used by police or security forces to patrol harbors, waterways, lakes, or open water areas, usually by boat.
The station supports patrol and security work on water. Harbors and inland waterways are included alongside lakes and open-water areas.
Boat patrol is usual without being the only possible method. The water-patrol duty distinguishes the base from an ordinary marina or passenger boat terminal.
