Introduction to the water park: It was originally a Huayuankou Water Supply Project built in 1958. Due to low design standards, the completed earth dam was forced to explode during a flood in 1960, leaving only these eighteen holes. The lock bridge, stilling basin and a miraculously remaining dam in the river remain to this day. The water park covers an area of 461 acres, and the water quality is clear and transparent. People often fish and boat here.
