Huai Si Tho Reservoir

Huai Si Tho Reservoir is a large artificial reservoir in Bung Subdistrict, Mueang Amnat Charoen District, Amnat Charoen Province, northeastern Thailand. Built for irrigation and water storage, it has become a local recreation and scenic spot. The reservoir features an earthen dam, open water, surrounding paddy fields and a roadside viewpoint with pavilions. It is known for sunset views, birdlife and as a venue for local festivals.

Visitors can expect a large open reservoir with an earthen embankment, calm water, and wide rural views over paddy fields and low hills. A paved road runs along the dam crest with pavilions and seating for sightseeing and photography. The area is open and breezy, used by locals for picnics, cycling, jogging and fishing. There are no large tourist structures, but viewpoints and lakeside spots allow for relaxed viewing, especially at sunset.

Constructed as an irrigation and water storage project to support agriculture in Mueang Amnat Charoen District. The earthen dam impounds Huai Si Tho stream to provide year-round water for paddy fields and local consumption, later developed as a community recreation area.

Serves as a community leisure and gathering place for residents of Amnat Charoen. Used for local merit events, evening recreation and annual festivals such as Loy Krathong, reflecting its role as a shared public water resource and scenic amenity.
