Gangjeong Goryeongbo.

[Asia Economy Yeongnam Reporting Headquarters Reporter Koo Dae-sun] The Daegu Regional Environmental Office announced on the 6th at 3 p.m. that the algae warning issued for Nakdonggang Gangjeong Goryeongbo has been lifted.

An algae warning is issued at the 'Attention' level when the number of harmful cyanobacteria cells is observed to be 1,000 cells/mL or more twice consecutively, at the 'Caution' level when it is 10,000 cells/mL or more, and is lifted when the count is observed to be below the attention threshold (1,000 cells/mL) twice consecutively.

Analysis of samples collected from Gangjeong Goryeongbo on September 26 and October 4 showed cyanobacteria cell counts of 765 and 103 cells/mL, respectively, leading to the lifting of the algae warning.

Gangjeong Goryeongbo had risen back to the 'Attention' level two weeks after the algae warning was lifted on September 8, but due to a recent drop in water temperature and a decrease in green algae, the algae warning was lifted again after two weeks.

Although the algae warning at Gangjeong Goryeongbo has been lifted, the 'Attention' level remains in place at Chilgokbo due to the continued presence of green algae.
