Naruebodindrachinta Reservoir

Naruebodindrachinta Reservoir is a large artificial reservoir in Kaeng Din So Subdistrict, Na Di District, Prachinburi Province, eastern Thailand. Created by damming Huai Samong, a tributary of the Prachin Buri River, it was developed as a royal initiative project of King Bhumibol Adulyadej. Notable for its 295-million-cubic-metre capacity, flood mitigation and irrigation functions, and scenic setting against the Sankamphaeng Range near Thap Lan National Park, it features a drivable dam crest and viewpoint.

Visitors can expect a vast open reservoir surrounded by forested mountains of the Sankamphaeng Range on the edge of Thap Lan National Park. The main visitor area is the dam crest and viewpoint, accessible by car or on foot, offering panoramic views of the water, embankment, spillway and distant hills. The environment is open and windy with limited shade. Activities are low-key, focused on sightseeing, photography and enjoying sunset views over the water.

Initiated as a royal project of King Bhumibol Adulyadej (Rama IX) in 1978 to address flooding and water shortage in the Prachin Buri River basin. The Huai Samong water management project was approved in 2009, construction of the dam and reservoir began thereafter and was largely completed in 2016-2017. The name Naruebodindrachinta, meaning reservoir created by royal resolve, was granted by King Maha Vajiralongkorn (Rama X). The reservoir provides irrigation for about 111,300 rai and helps regulate downstream flooding.

Represents a royally-initiated water resource development valued locally for water security and flood protection, and is a recognized landmark of Na Di District associated with the late King Bhumibol Adulyadej's water management initiatives.
