Before powered pumps, wooden waterwheels lifted Yellow River water to fields along the banks. Local accounts trace the Lanzhou wheel to the Ming period and credit official Duan Xu with adapting a southern water-lifting wheel to the Yellow River’s stronger current. Buckets fixed around the rim dipped into the river as the wheel turned, then emptied into channels that carried water to farmland. The machine joined local engineering to the demands of irrigation in an arid valley.

Waterwheels that lifted the Yellow River
Lanzhou’s wooden waterwheels used the river current to raise water into irrigation channels. The Waterwheel Expo Park keeps the form visible beside the south-bank promenade.

A working display by the river
The Waterwheel Expo Park on South Binhe East Road brings several parts of the story together: a waterwheel garden, an open plaza and a cultural area. Large wheels stand beside the river, while exhibits and interpretive displays introduce the device and its history. A statue of Duan Xu recalls the figure associated with its development. The park makes an agricultural technology visible in the city, where few people now rely on river wheels for daily irrigation.
An older rhythm of the waterfront
Local historical accounts report that more than 250 waterwheels stood along the riverbanks by 1952, a scale behind Lanzhou’s former reputation as a city of waterwheels. Modern bridges, roads and parks have since changed the waterfront. The wheels remain a way to understand how residents once moved river water uphill to fields. Zhongshan Bridge, farther along the same urban river, represents a different response to the Yellow River: a fixed route for people and vehicles, now used by pedestrians.
