Poyang Lake enters a low water period. (Phtoto: huanqiu)

Poyang Lake, China's largest freshwater lake, has entered a low water period due to drought in east China's Jiangxi Province. 
Water levels in the Poyang Lake have been decreasing over the past few months. On Monday morning, the lake's water level in Xingzi County fell below the 10-meter mark, meaning that this year's drought period came 13 days sooner compared with last year's. 
Currently, a huge number of migratory birds are flying south in droves to get through the winter, and tens of thousands of birds have arrived at Poyang Lake. 
Local authorities said that if the birds find it hard to get food due to low water levels, they will provide food for the birds in key areas.
