Ronghua Dam is a concrete arch dam crossing the Dahan River, a tributary to the Tamsui River, in Fuxing District, Taoyuan City, Taiwan.[1]
The dam was started in December 1978 and finished in June 1984.[2] The cost was NT$1.83 billion.The Ronghua Dam is within the catchment area of the Shihmen Reservoir, 27 kilometers upstream of the Shihmen Dam in the Dahan River gorge. The dam's main function is to prevent sand from moving downstream and building up as silt in the Shimen Reservoir. It also serves as a diversion point for sending water to a 40,000 kilowatt hydroelectric plant located 6km (04miles) downstream.
As of 2012, the dam has no effective storage capacity, as almost its entire reservoir has been filled by sediment.
