SEASONAL LAKE Meaning and
Definition
-
A seasonal lake refers to a body of water that only exists during specific periods of the year, usually during a particular season or as a result of seasonal variations in precipitation. Also known as intermittent lakes or ephemeral lakes, these water bodies undergo cyclic changes in water availability, typically appearing during wet seasons and disappearing during dry seasons.
When seasonal lakes receive adequate rainfall or meltwater from nearby mountains, they fill up with water, forming a temporary lake or pond. However, they gradually decrease in size or completely dry up when evaporation, infiltration, or water loss surpasses their water input. This phenomenon commonly occurs in arid and semi-arid regions where the yearly precipitation may be insufficient to sustain a permanent lake or where the climate exhibits distinct wet and dry seasons.
These temporary water bodies are crucial ecosystems that support a variety of flora and fauna, including migratory birds, amphibians, and invertebrates. Due to the fluctuating water levels, seasonal lakes often possess a unique biodiversity adapted to their specific conditions. These ecosystems can also provide habitats for breeding, feeding, and shelter for numerous wildlife species.
Additionally, seasonal lakes have significant cultural and economic importance in certain regions. They can serve as vital water sources for agriculture, domestic use, and livestock during their existence, contributing to local economies and sustenance. Furthermore, some communities may have traditional activities or ceremonies associated with the cyclic formation or disappearance of these lakes, adding cultural value to their existence.
Etymology of SEASONAL LAKE
The word "seasonal" originated from the Latin word "sētiōnālis" which means "pertaining to a particular season". It is derived from the word "sētiō", meaning "pertaining to a period of time" or "pertaining to a particular season or harvest". The word "lake" is derived from the Middle English word "lake" or "lakke", which was borrowed from the Old French word "lac", ultimately coming from the Latin word "lacus", meaning "lake" or "pond". The term "seasonal lake" combines these two words to refer to a body of water or a lake that forms during a specific season or time period, typically during the wet season and dries up during the dry season.
