Water Intakes

Tung Chung River is a major water source of Shek Pik Reservoir. On average, it channels 10 million m3 of water into the reservoir each year – ie, 40% of the reservoir's total capacity. Three intakes from the river lie near Shek Pik Au and the Country Park Management Centres at Tung Chung Road. Water collected passes through a 3.8-km pipe connecting Ngong Ping and Lantau Peak to reach Shek Pik Reservoir.

Channelization

As Tung Chung River is farther away from Tung Chung Town, channelization was only carried out in a downstream section of the East Stream originating from Sunset Peak, and the few tributaries that intersect with Tung Chung Road. The remaining sections have been kept in their natural state, especially the estuary – making this one of Hong Kong's few relatively large rivers that has not undergone channelization and reclamation at their estuaries.

Works on Tung Chung Road

The government launched Improvement to Tung Chung Road in 2001, to improve the substandard road for road safety and ensure traffic linkage between north and south Lantau. Tung Chung Road is within Shek Pik Reservoir's water gathering ground, and runs alongside Lautau North and South Country Park and Lautau North (Extension) Country Park. To minimize ecological damage, several mitigation measures are implemented, such as building bridges across all sensitive channels, improvement in culverts inlets and outlets, planting of native plants as ecological mitigation, and relocation of valuable species.

Tung Chung River Incident

The Tung Chung River rock digging incident occurred in 2003. A river project was carried out in the section of East Stream of Tung Chung River, between Shek Lau Po and Shek Mun Kap, stretching about 330 metres, by the Tung Chung Rural Committee (TCRC). It was later discovered that no government authorisation had been obtained, and the work was widely suspected to have been aimed at collecting boulders and pebbles from the river. The rock digging incident was widely covered by the media, and loopholes in local river conservation were exposed, attracting public concern and intervention by several government departments. The TCRC was required to restore the damaged river to its natural state.
