Self-cleaning of a stagnant lake occurs through a natural process called self-purification. This process involves the breakdown of organic matter and pollutants by microorganisms such as bacteria and algae. These microorganisms consume the organic matter and pollutants, breaking them down into simpler, less harmful substances. Additionally, the movement of water, wind, and sunlight can also help to aerate the lake and promote the growth of beneficial microorganisms. Over time, these natural processes can help to improve the water quality and reduce the stagnation of the lake. **
