Lore & Background

Reader's Guide
The North Jiangsu Main Irrigation Canal is a multi-purpose project for flood control, irrigation, and power generation. A drainage canal on its north side drains flood areas, and the canal helps discharge floods when water volumes in the north area become serious. The canal also supports ship navigation and electricity generation, with hydroelectric power generators and ship locks built near sluices at Gaoliangjian and Buning. Associated structures include 36 culverts, 2 flood-release sluices, 4 road bridges, and a cross sluice at Gaoliangjian that strengthens draining capacity. The Jiangsu Irrigation Canal Management Office administers riverine engineering and resource provision, while counties and districts along the canal handle bank repair and administration.
