Datunhai Lake in Gejiu City, Honghe
Overview
Datunhai Lake (大屯海) is located in the central part of Honghe Hani and Yi Autonomous Prefecture (红河哈尼族彝族自治州), straddling Gejiu City (个旧市) and Mengzi County (蒙自县). Situated approximately 1.5 kilometers west of Datun Town (大屯镇), it borders Changqiao Lake (长桥海) to the east. This lake, formed by surface water accumulation in a basin, is a remnant of an ancient lake and is classified as a fault freshwater lake. According to the “Supplement to the Mengzi County Chronicles” (续蒙自县志), it was historically known as Li Hai (鲤海) or Yipicao Hai (矣皮草海), covering thousands of acres with fertile farmland along its coast.
Area Description
Datunhai Lake covers an area of 12.4 square kilometers, with a maximum storage capacity of 55.2 million cubic meters and an average depth of 4.5 meters. As the development of Yunnan’s southern central city progresses, the lake’s potential value and ecological role are becoming increasingly apparent.
The vast surface of Datunhai Lake presents stunning scenery, with fishing boats dotting the waters and gentle breezes creating ripples. Strolling along the lakeside feels like being by the ocean, especially during spring when the fields are lush and in autumn when golden rice waves sway. The air during rice bloom is fragrant, while the harvest season bathes the landscape in golden light.
Historical Significance
Historically, Datunhai Lake served as an important transportation route. It connects to Changqiao Lake, allowing goods transported by the Dian–Vietnam Railway (滇越铁路) to be transferred for shipping to Datun. The lake facilitated the transport of coal, grains, timber, textiles, salt, paper, sugar, and other necessities, with excess cargo stored in lakeside warehouses.
During the peak of water transport, over 500 ox carts awaited daily at the lakeside, and more than 50 large wooden ships operated on the lake. This vibrant trade continued until the completion of the railway section from Gejiu to Bisezhai in 1921.
Longwang Pavilion
At the center of Datunhai Lake is the Longwang Pavilion (龙王阁), built in the 13th year of the Guangxu era (光绪) in 1887. The pavilion has two stories: the first floor is square-shaped with stone walls to prevent water seepage, while the second floor is hexagonal, offering stunning views from its wooden structure. The pavilion appears especially striking in the morning mist.
Recent Developments
To address local water needs, a reinforcement project for Datunhai was initiated in 2003, backed by central government funding. With an investment of 46.99 million yuan, the lake’s capacity was increased to 55.2 million cubic meters, becoming Gejiu’s largest reservoir. The surrounding dam has become a scenic roadway for visitors to enjoy.
In 2005, Datunhai was included in the development plan for Gejiu and southern Yunnan, enhancing the area’s coastal scenery.
Cultural Events
Each year, three temple fairs are held at Longwang Pavilion, becoming cherished local traditions:
- Guanyin Festival (观音会) during the Spring Festival, praying for safety and blessings.
- Dragon Raising Head Festival (龙抬头会) on the second day of the second lunar month, offering sacrifices for good weather and abundant harvests.
- Release Festival (放生会) during the Dragon Boat Festival, where locals release fish and shrimp into the lake.
These events transform Longwang Pavilion into a lively hub, featuring food stalls and performances that create a vibrant atmosphere.
Environmental Concerns
Despite its beauty, the water quality of Datunhai has significantly deteriorated, with arsenic levels nearly 100 times over national standards, diminishing the lake’s former splendor.
