Caohai Wetland Park in Heqing County, Dali

Cao Hai (草海), located in Heqing County (鹤庆县) within the Yunnan Province (云南省), is truly a highland water town. Nestled in the Heqing Basin (鹤庆坝子), this region is fed by numerous springs and the Yangong River (漾弓江) watershed, resulting in a vast natural wetland. The shallow waters of Cao Hai are particularly famous in autumn when local villagers use wooden boats to harvest aquatic plants for fertilizer, giving the area its name.

Geographical Information

Cao Hai is classified as a highland freshwater lake, with a maximum depth of 2.6 meters and an average depth of 1.6 meters. The surface elevation is approximately 2193.2 meters above sea level, with an annual inflow of 2.4 million cubic meters of water. The wetland is divided into four sections: Beihai (北海), Zhonghai (中海), Nanhai (南海), and Donghai (东海). Its waters are interconnected with small streams and fields, resembling the picturesque landscapes of the Jiangnan (江南) water towns.

Seasonal Highlights

During the summer, the lake blooms with thousands of acres of red lotus flowers, creating stunning scenery. The shores of the lake also yield abundant water chestnuts and lotus roots. When the lotuses are in full bloom, the local Bai (白族) community participates in traditional "Shua Hai" (耍海) activities, where young men and women enjoy the beauty of the lake and mountains. They paddle boats, hike around the lake, play traditional three-stringed instruments, and sing Bai folk songs, fostering joy and entertainment. Many young couples find lasting love at these gatherings, forming lifelong partnerships.

Ecological Importance

Cao Hai Wetland plays a vital role in preventing soil erosion in the upper Yangtze River (长江) region and contributes significantly to environmental protection. It creates a unique natural tourism landscape that attracts visitors while also serving as a crucial ecological buffer.
