watershed

A watershed is an area of land where all the water that falls as rain or snow drains into a common outlet, such as a river, lake, or ocean. It includes the surrounding land that channels water through streams and rivers to reach that main body of water. Watersheds vary in size from small neighborhoods to large regions. They are important because they influence local ecosystems, water quality, and flood management. Protecting watersheds helps ensure clean water, rich habitats, and sustainable water resources for communities and wildlife.
