A watershed is an area of land where all the water drains into a common outlet, such as a stream, river, or lake. It is defined by the topography of the land, with higher elevations forming the boundaries of the watershed. The physical characteristics of a watershed can include its size, shape, slope, soil type, vegetation cover, and land use activities.
Organisms use a watershed for drinking water, absorbing nutrients, sheltering and reproducing. Watersheds provide habitats for various plants and animals to thrive, supporting biodiversity and ecological balance. The health of a watershed directly impacts the health and survival of the organisms living within it.
An example of a watershed is the Mississippi River watershed, which drains water from 31 U.S. states and two Canadian provinces into the Gulf of Mexico.
