China is facing a crucial flood control challenge. A swollen tributary of the Yangtze River has unloaded into a major reservoir in the central provinces of Henan and Hubei.
The Hanjiang River is the second largest tributary of the Yangtze, China's biggest river. The Danjiang River is a tributary of the Hanjiang. The water level of the Danjiang rose to over 217 meters on Saturday afternoon. Water flow was 10,000 cubic meters a second, the highest in half a century.
Early Sunday, the flood gushed into the Danjiangkou Reservoir, where the Danjiang and Hanjiang meet. It was more than 34,000 cubic meters a second. The deluge is the second biggest since the reservoir was built in 1968. And as the upper reaches of the Yangtze continue to rise, the Three Gorges Dam is expected to see a second flood peak.
