Engineers develop 'fish lane' for dam in Jiangxi

Engineers working on the Xiajiang Hydropower Project have designed a special "fish lane" to prevent migration patterns being affected by a dam on the Ganjiang River.

According to the plan, a 3-meter-deep open-air zigzag channel stretching 815 meters will be built into the dam, 155 km from Nanchang, the capital of Jiangxi province.

The zigzag design will reduce the gradient and water velocity, making it easier for the fish to swim upstream, said Liu Zubin, head of technology for the Xiajiang Hydropower Project team.
