Administrative Region
The Lukang Workstation was originally named the Toubian Workstation. It was officially renamed the Lukang Workstation in 1996 to align with the township’s name. As an irrigation workstation, its primary responsibilities include the maintenance and management of sluice gates, the upkeep of group irrigation canals, mediation and resolution of water-related disputes, promotion of water regulations and irrigation policies, drafting and implementation of irrigation plans, water quality monitoring, membership and irrigation land registry investigations, collection of various fees such as engineering costs, maintenance and management of public property, meteorological, hydrological, and soil observations, assisting with irrigation experiments and demonstrations, and handling tasks assigned by the management office.
The Toubianpi pond was reportedly established before the end of the Jiaqing period (before 1820), initiated by local farmers. Initially, it involved constructing an earthen dam to raise the water level for irrigation. In 1926, it was updated to a two-tiered concrete weir with sluice gates. In 1956, it was redesigned and rebuilt with 30 sluice gates, divided into two layers with 15 wooden gates on each layer (H=1.5; B=1.65). In 1983, it was rebuilt into a single layer with five gates. Due to severe saltwater corrosion near the coast, the gates were completely replaced with stainless steel ones between 2006 and 2007, and these are still in use today, benefiting farmers with irrigation water.
The Old Xinpi Canal was reportedly built by Huang Shuang in 1848 with private funding and was later upgraded to a U-shaped concrete canal. The Touzhuang sluice gate was also renovated into a rubber dam in 1996.

Irrigation Water Source
As this workstation is located in the northwestern part of Changhua, at the downstream end of the irrigation channels, it faces challenges due to weather conditions and being at the tail end of the water supply. This area relies entirely on return flows water for irrigation, which requires a significant number of large sluice gates that demand extensive personnel for management and discharge. Additionally, being close to the western coastal area makes the region vulnerable to saltwater intrusion from tidal levels, necessitating the use of multiple tidal gates to block seawater influx. The numerous sluice gates and the need for careful management are critical to the workstation’s operations.
The irrigation system intercepts return flows from Toubianpi along the Yangzicuo River, raising the water level to divert water through the Toubian Canal, Gouliang Canal, and Xin Canal into the villages of Dingcuo, Xuezi, Liaocuo, Gouqian, Zhaoan, Nanshi, and Yangcuo. Additionally, return flows from Fanyagou is intercepted by the Touzhuang Rubber Dam and channeled through the Old Xinpi Canal into the villages of Touzhuang, Caogang, Lunwei, and Shanliao.

Irrigation Region
The irrigation area of the Lukang Workstation extends north to Fanyagou, south to the urban area of Lukang Township, east to Andong Drainage, and west to Provincial Highway 17. The actual irrigated area is 1,314 hectares.

Agricultural Production
The primary crop produced in this region is rice, with most of the soil consisting of sandy loam.
