Mae Suai Reservoir lies in Ban Den Phu Wiang, Mae Suai District. Built in 1998, the reservoir stores water from the Mae Suai River and supports irrigation; it is also a scenic local excursion.
About the place and its management
The Mae Suai Irrigation Office, under Thailand’s Royal Irrigation Department, manages the dam and reservoir. Individual raft or restaurant businesses are operated separately.
Background and site character
The dam was constructed in 1998 to serve regional water management. Its combination of engineered embankment and concrete sections contrasts with the natural mountain setting.
What to look for
Compare the dam structure, expansive water surface and surrounding mountain slopes. A nearby hilltop stupa, Phra Maha Chedi Phra Borommathat Khum Wiang Suai, is another landmark in the reservoir area.
