   Shap Long Irrigation Reservoir and its catchments
    Site Description

Shap Long Irrigation Reservoir is located at Chi Ma Wan Peninsula on Lantau Island and is fed by unpolluted streams in the area.  The reservoir is in a sheltered valley and fringed with mature woodland.  Apart from a country trail, there is no development near the reservoir.  Due to its remoteness, this reservoir is virtually free from human disturbance.  As a result, there is no evidence of introduction of exotic species and it can support a large population of Rice Fish Oryzias curvinotus.

    Site Protection

The site is within Lantau South Country Park.
