The reservoir was built as part of a Royal Initiative project under King Bhumibol Adulyadej to improve water management for Nakhon Nayok farmers.
It is categorized as a medium-sized reservoir, primarily serving the irrigation needs of the Khao Phra and surrounding sub-districts.
The reservoir's water level is noticeably higher and more visually striking during the late rainy season, usually around October.
The site acts as a gateway to the broader natural landscape of the Khao Yai buffer zone, providing clear views of the mountain silhouettes.
Unlike more developed tourist reservoirs in Thailand, this site remains largely free of permanent, large-scale commercial structures along its perimeter.
Huai Prue Reservoir is a Royal Initiative Project located in the Nakhon Nayok province, designed to support local irrigation and agriculture. The site features an earthen dam that creates a large, scenic water catchment area framed by the backdrop of the Khao Yai mountain range. It functions as a public leisure space where visitors can access the shoreline for picnics and relaxation. The reservoir is situated within the Khao Phra sub-district, approximately 15 kilometers from the main town center of Nakhon Nayok. It is part of a broader water management network that regulates supply for surrounding agricultural lands. The area is largely uncommercialized, retaining a natural, rural atmosphere. Access to the water's edge is generally available, though swimming is strictly prohibited for safety reasons. It serves as a popular destination for local cycling groups and those seeking a quiet environment away from urban congestion.
The crest of the earthen dam provides the widest panoramic view of the water with the mountain range in the background.
Bring your own refreshments and portable seating, as on-site food and drink facilities are minimal.
Ensure your vehicle is fueled before departing Nakhon Nayok town, as the road to the reservoir becomes more rural.
Apply mosquito repellent if planning to stay near the treeline or tall grass during the late afternoon.
Do not attempt to swim in the reservoir, as the currents and underwater terrain are unpredictable and dangerous.
Maintain a quiet environment to respect local residents; remove all personal trash upon departure; swimming in the reservoir is prohibited.
