Timah Tasoh Lake

Timah Tasoh Lake is a large man-made reservoir in Beseri, Perlis, northern Malaysia, created by the Timah Tasoh Dam on the Sungai Timah and Sungai Tasoh rivers. Surrounded by limestone hills including Bukit Chabang, it serves as a water supply, flood mitigation and irrigation reservoir. The lake is notable for its scenic waters, islands, and tranquil rural setting near the Malaysia-Thailand border.

Visitors can expect a large open reservoir with calm waters, small islands and a backdrop of limestone hills and paddy fields. The area features roadside viewpoints, lakeside stalls and open spaces for sightseeing and photography. Visitors can view the dam structure, enjoy lakeside picnics, observe local fishing activity and experience a quiet rural landscape. The site is open and largely undeveloped as a formal park.

Timah Tasoh Dam was constructed between 1987 and 1992 across Sungai Timah and Sungai Tasoh to provide water supply, flood control and irrigation for Perlis. The impoundment created Timah Tasoh Lake with a catchment area covering the Nakawan Range foothills. It remains a key water infrastructure for the state.
