What do watersheds drain into?
A watershed is an area of land that catches rain and snow, and allows it to drain into a stream, river, lake or seep into the ground as groundwater. Open watershed: All water from a watershed eventually drains into the ocean.
What causes the drainage of water from a watershed to a river?
When rain falls on dry ground, it can soak into, or infiltrate, the ground. This groundwater remains in the soil, where it will eventually seep into the nearest stream. Some water infiltrates much deeper, into underground reservoirs called aquifers.
What is the difference between watershed and drainage basin?
Drainage basin: A drainage basin is an extent of land where water from rain or snow melt drains downhill into a body of water, such as a river, lake, reservoir, estuary, wetland, sea or ocean. Watershed: In the technical sense, a watershed refers to a divide that separates one drainage area from another drainage area.
How are a drainage basin watershed and a drainage divide related?
Drainage basin, also called catchment area, or (in North America) watershed, area from which all precipitation flows to a single stream or set of streams. The boundary between drainage basins is a drainage divide: all the precipitation on opposite sides of a drainage divide will flow into different drainage basins.
Can a watershed be fed by groundwater?
The boundaries of a surface watershed and groundwater recharge area can, but do not always, coincide. In recharge areas, surface waterbodies and groundwater are often interconnected. Lakes that appear to have no major inlet are often fed by groundwater.
What is a watershed simple definition?

Why is a watershed important?
Watersheds are important because the surface water features and stormwater runoff within a watershed ultimately drain to other bodies of water. It is essential to consider these downstream impacts when developing and implementing water quality protection and restoration actions.
What are the 3 main functions of a watershed?
WATERSHED FUNCTIONS There are three processes within a watershed that can protect water quality if pre- served: water capture, water storage, and water release. A number of circumstances that can interrupt the capture, storage, and beneficial release of water are beyond human control.
What is a healthy watershed?
A healthy watershed is a well-balanced system, capable of sustaining a variety of environments and many forms of life. In a healthy watershed, water, soil and air are clean. People, as well as fish and wildlife, have the water, food, shelter, and other resources they need to survive.

How does a watershed work?

Who lives in a watershed?
Everyone lives in a watershed. Even in deserts where it is extremely hot and dry, water is shed. Deserts typically receive ten inches or less of precipitation per year. The rain usually comes in brief downpours resulting in flooding as the water flows across the dry, caked soil.
Who is responsible for the health of a watershed?
Why is EPA Concerned with Healthy Watersheds? One of EPA’s most important jobs is to work with states and others to achieve the Clean Water Act’s primary goal – restore and maintain the integrity of the nation’s waters.
