Limnological study is the scientific study of inland waters, such as lakes, ponds, and rivers. It involves the study of physical, chemical, and biological characteristics of these bodies of water, as well as their interactions with the environment. Limnological study is an important part of understanding the health of aquatic ecosystems and can help inform decisions about water management and conservation. The term 'LAKE' is used to refer to a body of water that is surrounded by land and is not part of an ocean or sea.
