Yunlong Lake, Urban park with lake in Xuzhou, China.

Yunlong Lake is an urban park in Xuzhou featuring a water surface of around 8 hectares within a 25-hectare total area. The space includes walking paths, gardens, and multiple sections for outdoor activities.

Yunlong Lake was originally a low-lying area known in historical records as Shigou Lake. It was enlarged into a reservoir to control flooding and took its name from Yunlong Mountain at its foot. In August 2016 the scenic area was rated AAAAA by the China National Tourism Administration.

The lake was historically called Shigou Lake (Stone Dog Lake) before being renamed for Yunlong Mountain at its foot. Its shores hold ancient-style bridges and buildings, and the water carries lotus plants, while peach, willow, plum and red maple trees line the surroundings. Archaeological finds of Han pictorial stone carvings have been made in the area.

Yunlong Lake lies south of Xuzhou, with Yunlong Mountain to its east; the scenic area holds ancient-style bridges and buildings, including a two-storey wooden pavilion over the water reached by a walkway and a staircase on its left. Paths run along the shore, where peach, willow, plum and red maple trees stand and lotus grows in the water.

The lake was long called Shigou Hu, "Stone Dog Lake", before it was enlarged into a reservoir to control flooding and renamed for Yunlong Mountain at its foot. The scenic area also holds Han-dynasty stone reliefs found by archaeologists.
