Though not like algae that would affect the water quality, the rapid growth of duckweed also caused big concern from the public over another possible algae attack on the water of the lake, which is known as the 'lung of the city' of Baoji.

However, an official from the Jinwei Lake management office said in an earlier statement that the quality of the lake water won't deteriorate and duckweed can on the contrary purify the lake water as duckweed is a delicious food for fish.

According to the report, the rapid growth of duckweed in the lake is caused by an increasing amount of nutrition in Jinwei Lake under hot weather.

The lake is located in the centre of Baoji and covers an area of 1.4 million square meters. It is a popular recreation area for the locals.
