Sungai Selangor

The Sg Selangor Basin covers an area of about 1,960 km sq., which is nearly a quarter (24.6%) of the total area of the State of Selangor, and approximately 70 km long and 30 km wide. The Basin is located to the north of Kuala Lumpur City, bounded by the Sg Klang Basin in the south and Sg Bernam Basin in the north, and encompasses the Districts of Gombak, Kuala Selangor and Hulu Selangor in 19 Mukims. The Basin is rich with natural and ecological systems. The upper Basin provides a green and pristine upland with unique flora and fauna while the downstream areas have the natural wonder, internationally known firefly colony at Kg Kuantan.

Rapid urbanization in the Sg. Selangor basin has resulted in many conflicting interests of water users and environmental problems. The control of both the quantity and quality of runoff is now being seen to be of major importance in basin management and its receiving waters. Key issues that beset the Basin include declining water quality in its rivers, encroachment into most of its riparian reserves, downstream flooding and significant loss of forest cover.
