It formed a part of the limit of the lease of the New Territories in 1898 in the Convention for the Extension of Hong Kong Territory (known also as the Second Convention of Peking).

It separates Yuen Long District, North District of Hong Kong, and the city of Shenzhen, Guangdong. Its source is at Wutong Mountain, Shenzhen. Its tributaries includes Ping Yuen River, Shek Sheung River, Sheung Yue River, Ng Tung River, Buji River and Tan Shan River. The Shenzhen Reservoir also flows into the river when it is full.

The river flows into Deep Bay (also known as Hau Hoi Wan and Shenzhen Bay). The Mai Po Marshes is at its estuary.

Efforts have been made to alleviate flooding and pollution problems through river draining, which produced the Lok Ma Chau Loop.
