Why does Shidao Phoenix Lake stink?

Sorry, I'm not sure why Shidao Phoenix Lake stinks. However, I can provide some possible reasons for your reference:

1. Environmental pollution: If there are a large number of industrial pollution sources, agricultural pollution sources or domestic garbage around Fenghuang Lake, these pollutants may enter the lake, resulting in water quality deterioration and odor.

2. Eutrophication of water body: Too many nutrients (such as nitrogen and phosphorus) enter the water body, which may lead to eutrophication of water body, thus causing algae to multiply in large numbers, consuming oxygen in water and producing peculiar smell.

3. Fermentation of sediments at the bottom of the lake: If there is a large amount of organic matter at the bottom of the lake, it may be fermented under anaerobic conditions, producing gases such as hydrogen sulfide, thus producing odor.

In order to know the exact cause of odor in Shidao Phoenix Lake, it is suggested to contact the local environmental monitoring department or professional organization for investigation.
