Oujiang River, the second largest river in Zhejiang Province, flows into the East China Sea alone. It is located in the south of Zhejiang Province. It was once known as Yongning River, Yongjia River, Wenjiang River and Shenjiang River in history. Originating from guomaojian, the northwest foot of Baishanzu at the junction of Longquan City and Qingyuan County, it flows from west to East and runs through the whole mountainous area of southern Zhejiang. It flows through Lishui, Wenzhou and other cities, with a total length of 388 kilometers and a drainage area of 18028 square kilometers. It flows from Wenzhou City to Wenzhou Bay in the East China Sea. The average annual runoff of Oujiang River is 20.27 billion cubic meters (the maximum is 30.85 billion cubic meters, the minimum is 9.28 billion cubic meters), the theoretical reserve of water energy is 1.9 million kilowatts, the developable installed capacity is 1.7 million kilowatts, and the annual power generation is 5.4 billion kilowatt hours. Oujiang Estuary is one of the major estuaries after the Yangtze River Estuary, Yellow River Estuary, Pearl River Estuary and Qiantang River Estuary. The shipping industry is developed.

The upstream of Oujiang River is an important hydropower development area. Lishui City is awarded as "the first hydropower city in China" by the Ministry of water resources. There is a famous Jinshuitan hydropower station.

The lower reaches of Oujiang River is the center of Dongou ancient culture and the main industrial and agricultural economic zone of Zhejiang Province. Wenzhou's electrical machinery and equipment manufacturing industry, leather, fur, feather (down) and its products industry, power and heat production and supply industry, general equipment manufacturing industry, textile and clothing industry, rubber and plastic products industry are in the forefront of Zhejiang Province.

The natural environment in the basin is well protected, with tourist attractions all over the country.

It is the second largest river in Zhejiang Province. The main and tributaries of Oujiang River are distributed in branches, and most of them are parallel to the trend of mountains. The terrain on both sides of the valley is steep, the precipitation converges quickly, the beaches bend more, and the floods rise and fall suddenly. Below the Wenxi river is the tidal reach, usually navigable 10-200 tons of ships, waiting for tide can pass 500 tons of seagoing ships. From Wenzhou to the first 14.9 kilometers, 3000 tons of seagoing ships can enter and leave when waiting for tide.

The main stream of Oujiang River is divided into three sections from the source to the estuary, namely Longquan River, Daxi River and Oujiang River.
