A watershed, also known as a drainage basin or catchment area, is a geographical area of land that drains water, including rainfall and snowmelt, into a common outlet such as a river, lake, or ocean.
Watersheds are natural hydrological boundaries that determine the flow of water and the distribution of nutrients and pollutants.
They play a crucial role in the management of freshwater resources, ecological health, and environmental conservation. Understanding and protecting watersheds is essential for ensuring the sustainable use of water and preserving the health of aquatic ecosystems.
