Hushan Dam was designed as a collaborative water resource project with the neighboring Linnei Weir to ensure stable supply for Yunlin, Chiayi, and Tainan.
The reservoir's total storage capacity is approximately 53.6 million cubic meters.
The site was constructed to address long-term land subsidence issues in the Yunlin area caused by groundwater over-extraction.
The embankment is a concrete-faced rockfill dam design.
The reservoir's water is sourced via an inter-basin transfer system from the Qingshui Creek.
The perimeter area was landscaped to encourage local biodiversity, including various species of butterflies and birds.
It is one of the few reservoirs in Taiwan that operates in tandem with a barrage system to regulate seasonal water flow.
Hushan Dam is a major water resource facility located in Gukeng Township, Yunlin County, featuring a expansive reservoir and a perimeter public footpath. The facility functions as an off-stream reservoir system, receiving water from the neighboring Qingshui Creek to augment regional water supply. The surrounding area comprises a paved walking circuit that offers panoramic views of the water body and the surrounding hilly topography. It is a dual-purpose site serving both as a vital hydraulic engineering project and a recreational walking destination. The reservoir spans approximately 3.2 square kilometers at full capacity. The trail is flat and well-maintained, making it accessible for pedestrians and light exercise. It is situated within a quiet, rural landscape, distinct from urban tourist centers.
The center of the dam embankment looking toward the reservoir expanse during the golden hour.
Bring sun protection, as the dam wall is wide and exposed with almost no natural shade along the path.
Check local weather reports for high wind warnings, as the open expanse of the reservoir can experience significant gusts.
Carry sufficient drinking water as there are limited commercial facilities directly on the dam perimeter.
Attempting to walk the entire perimeter during the peak of midday summer heat; drones are strictly prohibited due to local flight restrictions near water infrastructure.
Stay within marked pedestrian zones; keep noise levels low to avoid disturbing local wildlife; do not attempt to enter the water.
