Formed during the Himalaya orogeny 2.5 million years ago, Huoquan Spring has good water quality and a large and stable outflow at 3.67m 3 /s, ready for development and utilization. In the 6th century, Li Daoyuan mentioned Huoquan Spring in his Commentary on the Waterways Classics, describing its location, flow direction, and the deep pond it had formed.
The earliest known written records of Huoquan Spring Irrigation System were made during the Zhenguan Period (627 649) of the Tang Dynasty, which are about its southern and northern main canals. According to the Memorial Stele of Reconstructing the Water God Temple erected in 1283, the Irrigation System had four canals, nurturing a large number of villages in the Zhaocheng and Hongtong Counties with bumper harvests and good environment.
