Yueyaquan is a crescent-shaped lake in an oasis, 6 km south of the city of Dunhuang in Gansu Province, China. It was named Yueyaquan in the Qing Dynasty. According to measurements made in 1960, the average depth of the lake was 4 to 5 meters, with a maximum depth of 7.5 meters. In the following 40 years, the depth of the lake continually declined. In the early 1990s, its area had shrunk to only 1.37-acre (5,500 m2) with an average depth of 0.9 meter (maximum 1.3 meter). Although the local government had plans to fill the lake and restore its depth, a lack of funding delayed the project. The lake and the surrounding deserts are very popular with tourists, who are offered camel and 4x4 rides.
