Dianchi Lake, also known as Kunming Lake, is the largest freshwater lake in China's Yunnan province. It is located on the Yunnan-Guizhou Plateau at the foot of the Western Hills. Spanning approximately 300 square kilometers, Dianchi Lake plays a critical role in the ecology and economy of the region. It provides water for irrigation, aquaculture, and sustenance for nearby urban areas. The lake is a key tourist attraction in Kunming, known for its scenic beauty and as a habitat for a wide variety of birds and aquatic life. However, it has faced environmental challenges, including pollution and eutrophication, which have led to considerable efforts to restore its water quality. Around the lake, visitors can find several parks, such as Haigeng Park, ethnic villages, and other cultural sites. The area is also known for its vibrant birdlife, making it popular among birdwatchers, especially during migrations when many species stop at the lake.
