The destruction of Tung Chung River in 2003

The stream section between Shek Mun Kap (石門甲) and Shek Lau Po (石榴埔)

of theTung Chung Stream supports at least seven species of native fishes, which

are of high conservation value.

In 2003, the affected section of Tung Chung River was dominated by sandy

substrate. The stream bank on the side between the stream and Tung Chung

Road was highly unstable, which were mainly formed by loosely placed cobbles,

with all the riparian vegetation removed. Such environment provides no refuges

for stream organisms, including fishes, particularly during the period of high

water flow after heavy rains. The small sized substrate particles (sand and cobbles)

would also be easily carried downstream during high stream flow, directly

affecting the downstream Drainage Service Department channelized section

of Tung Chung Stream.
