2. About 曲渕ダム
Description & Purpose
曲渕ダム is a gravity dam located in the central district of Maebaru (馬場町), Fukuoka Prefecture. While official specifications such as height and reservoir capacity are not publicly listed, the structure serves primarily for water resource management—supporting local irrigation, flood control, and supplemental municipal supply for the surrounding communities.
The dam’s reservoir creates a calm, mirror‑like surface that reflects the rolling hills and seasonal foliage, offering a picturesque backdrop for visitors. Its concrete façade blends into the landscape, emphasizing functionality over flamboyance, yet the engineering elegance is evident in the clean lines and sturdy construction.
Historical Context
Built during a period of rapid post‑war development in Japan, 曲渕ダム reflects the nation’s broader push to modernize rural water infrastructure. Although exact construction dates are not widely documented, the dam’s existence aligns with the nationwide effort in the 1960s‑1970s to secure reliable water sources for agriculture and growing urban populations in Kyushu.
Local Significance
For residents of Maebaru‑chuo and neighboring towns, the dam is more than a concrete barrier; it’s a community landmark. Seasonal festivals occasionally incorporate the reservoir’s shoreline, and local schools use the site for educational field trips focused on hydrology and environmental stewardship. The dam also contributes to the region’s eco‑tourism by providing a safe, scenic spot for birdwatching, especially during migration periods when waterfowl gather near the water’s edge.
