Established in 1842 during the Qing Dynasty, Houzhuangzi Pond has long utilized water from the Bajiao River for irrigation. In 1956, after a typhoon destroyed its grass embankment, the Douliu Irrigation Association, with support from the Sino-American Joint Commission on Rural Reconstruction and U.S. aid, reconstructed the embankment with a six-gate sluice structure. This improvement allowed for the irrigation of 362 hectares of farmland, establishing the pond as a vital water source for the Douliu area. Over six decades, the sluice gate deteriorated, and its piers began to impede water flow, hindering effective drainage for the upstream Longtan community along the Bajiao River. In response to local residents' petitions, a renovation project was completed in 2017, resulting in a modernized headworks that effectively serves dual purposes: irrigation and flood control.
