Dong River
The north branch of the Dong River, near where it converges with the main stream of the Pearl River, photographed from the Dong River Viaduct of S3 Guangzhou-Shenzhen Riverside Expressway, crossing boundary between Dongguan and Guangzhou.
The Dong River is a major source of water for megacities in Pearl River Delta, including Hong Kong, Shenzhen, and Guangzhou. The Hong Kong Government has purchased Dong River water from Guangdong since 1965. Over 70 percent of domestic water in Hong Kong is imported from the Dong River. Its discharge totals roughly 807.5 cubic meters per second (28,520 cu ft/s).
Historical findings
A dinosaur egg fossil dated back to the Late Cretaceous was discovered by primary school student named Zhang Yangzhe while playing near the Dong River in 2019 in July. The boy's mother, Li Xiaofang, later contacted the Heyuan Dinosaur Museum members, and under their excavation guidance more than 10 dinosaur egg fossils each about 9 centimeters in diameter and dating back to 66 million years were revealed.
