Watershed- the area of land where all of the water drains into a common water body, such as a river, lake, or ocean.
The area from which water drains into a river is called the river's watershed or drainage basin. It includes all the land and waterways that contribute runoff to that particular river system. Rainfall and other sources of water collect in the watershed, eventually flowing into the river and its tributaries.
