城門河
The original Shing Mun River began at Needle Hill, and flowed into the former Tide Cove (Sha Tin Hoi), a shallow bay. In the 1970s, Tide Cove was reclaimed and turned to Sha Tin New Town. The river was extended through a 7 km long, 200 m wide artificial channel in the middle of the area to flow into Tolo Harbour. Other rivers that had originally flowed into Tide Cove are now tributaries of Shing Mun River in the form of concreted nullahs.
