It is a natural depression at the lowstreams of the five rivers: the Ganjiang River, the Fuhe River, the Xinhe River, the Raohe River, and the Xiushui River.

all the surface runoffof the province flows into Lake Boyang through the Boyang
River and the Changhe River as well as the five rivers mentioned above, which
spread around the lake like a spoke, then flows into the Changjiang River through
the outlet of the lake after being regulated and stored
