Detailed explanation-1: -A watershed is an area of land that drains rainfall and snowmelt into streams and rivers.

Detailed explanation-2: -A watershed is the area of land (catchment area) that captures rain and snow, and then stores, filters, seeps or drains this water into a common water body (marsh, stream, river, or lake).

Detailed explanation-3: -The watershed collects rain and snowmelt, and delivers it to that body of water. Some of it is intercepted and used by trees and other vegetation. Some flows overland in streams and rivers. Some soaks into the soil, which filters the water as it travels downward to be stored in underground aquifers.

Detailed explanation-4: -The word “watershed” is sometimes used interchangeably with drainage basin or catchment. Ridges and hills that separate two watersheds are called the drainage divide. The watershed consists of surface water–lakes, streams, reservoirs, and wetlands–and all the underlying groundwater.

Detailed explanation-5: -A river basin is the portion of land drained by a river and its tributaries. It encompasses all of the land surface dissected and drained by many streams and creeks that flow downhill into one another, and eventually into the Milwaukee River.
