Background
         Tha Thung Na Dam is located behind Srinagarind Dam. The dam construction project was under the Khwae Yai River Basin Development Plan. It was built across Khwae Yai River at the area of Ban Tha Thung Na, Chong Sadao Sub-district, Mueang District, Kanchanaburi Province. The construction started in December 1977 and was completed in March 1981. The official opening of the dam was performed on April 16, 1978.
         Tha Thung Na Dam can draw the water used for power generation in Srinagarind Dam to generate electricity again. Moreover, the water in Tha Thung Na Dam can be pumped back for power generation in Srinagarind Dam. This is an efficient water resource management.
