Sand mining has led to deepening and widening of the Lake Poyang channel, the largest freshwater lake in China and a biodiversity reserve of exceptional importance, and to an increase in water discharge into the Yangtze River. This may have influenced the lowering of the lake’s water levels, which reached a historically low level in 2008.

Irresponsible sand mining is also a huge threat to the river banks, bridges, and nearby structures. It also affects the contiguous groundwater system and the usages that local residents make of the river. Sand mining can be responsible for the destruction of riparian and aquatic habitat through huge changes in the channel morphology.
