Tumen River

geography Maturity 7-9 Next article →

The Tumen River is a long river in northeast Asia. It starts on the slopes of Mount Paektu. From there, it flows into the Sea of Japan. The river acts as a border for three places. It sits between China, North Korea, and Russia.

The river name comes from a Mongolian word. That word means "ten thousand." In Russia, the name means "foggy." Many special fish live in the water. These include the Tumen lenok and the bighead gudgeon. In 2016, China put 800,000 salmon seedlings into the river. They did this to help the fishing industry.

The Tumen is often narrow and shallow. This makes it different from the Amnok River. The Amnok is deep and moves very fast. Because the Tumen is shallow, people sometimes cross it on foot. In the winter, the river freezes. This allows people to walk across the ice. Some people use the river to leave North Korea. They may wait for a long time to find the right moment to cross.
