Detailed explanation-1: -What is a Watershed? A watershed is simply the geographic area through which water flows across the land and drains into a common body of water, whether a stream, river, lake, or ocean.

Detailed explanation-2: -A watershed is the region draining into a river, river system, or other body of water and may also be referred to as a drainage basin. How a watershed is shaped will determine how it drains, where flooding occurs, and how water quality is affected.

Detailed explanation-3: -A watershed is an area of land that drains or “sheds” water into a specific waterbody. Every body of water has a watershed. Watersheds drain rainfall and snowmelt into streams and rivers. These smaller bodies of water flow into larger ones, including lakes, bays, and oceans.

Detailed explanation-4: -For example, the watershed of a lake would include not only the streams entering that lake but also the land area that drains into those streams and eventually the lake. Drainage basins generally refer to large watersheds that encompass the watersheds of many smaller rivers and streams.

Detailed explanation-5: -Macro watershed (> 50, 000 Hect) Sub-watershed (10, 000 to 50, 000 Hect) Milli-watershed (1000 to10000 Hect) Micro watershed (100 to 1000 Hect) Mini watershed (1-100 Hect)
