Define watershed. watershed synonyms, watershed pronunciation, watershed translation, English dictionary definition of watershed. n. 1. The entire region draining into a river, river system, or other body of water: a list of reptiles found in the watershed. Also called basin , drainage...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.Ultimately that water will reach the ocean, usually via a major river system. That whole drainage area where all the water flows into one place is a watershed. Understanding watersheds is crucial in caring for our waterways and water quality.area of land where all the draining water goes into the same river system A watershed is _____. an area where all water drains into the same river system the start of a river systemFormerly, the term watershed was used for the divide of a drainage basin. Since the UN conference on water at Mar del Plata, Argentina in 1977, however, the term watershed has come to mean also the drainage basin itself [].Accordingly, "watershed is defined as any surface area from which runoff resulting from rainfall is collected and drained through a common point.

A watershed is an entire river system—an area drained by a river and its tributaries. It is sometimes called a drainage basin. Watersheds can cover wide areas. Runoff water from a large watershed in the midcontinental United States drains into the Gulf of Mexico through the Mississippi River system. The Amazon River watershed is huge, draining over a third of the entire South American continent.Do you know what a watershed is?

By protecting your watershed and theA watershed is an area of land that drains all the streams and rainfall to a common outlet such as the outflow of a reservoir, mouth of a bay, or any point along a stream channel.A watershed is a geographic region defined by the body of water that a given area drains into. Every inch of the planet is in one watershed or another, but knowing which water shed you are in is a powerful tool for understanding the relationship of where you live to the larger ecosystem.

A watershed is a turning point, or historic moment. The day you got your braces off might have been a watershed moment in your life.The province of Ontario requires the Niagara Peninsula Conservation Authority (NPCA) to manage the Niagara Peninsula watershed. This complex watershed includ...The landscape is made up of many interconnected basins, or watersheds. Within each watershed, all water runs to the lowest point - a stream, river or lake. On its way, water travels over the surface and across the farm fields, forest land, suburban lawns, and city streets, or it seeps into the soil and travels as ground water.A watershed is all of the land and water areas that drain toward a particular lake or river segment. Thus, a watershed (or drainage basin) is defined in terms of each selected lake or river, such as "Mississippi river watershed". Watersheds can be identified on different scales. Large scaleThe size of a watershed (also called a drainage basin or catchment) is defined on several scales—referred to as its Hydrologic Unit Codes (HUC)—based on the geography that is most relevant to its specific area. A watershed can be small, such as a modest inland lake or a single county.
While some watersheds are reasonably small, others surround 1000's of square miles and might comprise streams, rivers, lakes, reservoirs, and underlying groundwater which might be hundreds of miles inland.

The size of a watershed (also referred to as a drainage basin or catchment) is defined on several scales—referred to as its Hydrologic Unit Codes (HUC)—in line with the geography that is maximum relevant to its specific house. A watershed may also be small, reminiscent of a modest inland lake or a single county.
Conversely, some watersheds encompass thousands of sq. miles and may contain streams, rivers, lakes, reservoirs, and underlying groundwater which might be masses of miles inland. The biggest watershed within the United States is the Mississippi River Watershed, which drains 1.15 million sq. miles from all or portions of 31 U.S. states and two Canadian provinces stretching from the Rockies to the Appalachians!
Water from loads, and continuously thousands, of creeks and streams drift from upper flooring to rivers that at last finally end up in a higher waterbody. As the water flows, it steadily picks up pollution, which can have sinister results at the ecology of the watershed and, ultimately, at the reservoir, bay, or ocean where it ends up.
Not all water flows at once to the ocean, however. When rain falls on dry ground, it could possibly soak into, or infiltrate, the bottom. This groundwater stays in the soil, where it is going to sooner or later seep into the nearest movement. Some water infiltrates much deeper, into underground reservoirs referred to as aquifers. In other spaces, where the soil contains a lot of onerous clay, little or no water would possibly infiltrate. Instead, it quickly runs off to lower ground.
Rain and snowmelt from watersheds commute by the use of many routes to the sea. During classes of heavy rain and snowstorm, water might run onto and off of impervious surfaces reminiscent of parking a lot, roads, structures, and other structures because it has nowhere else to head. These surfaces act as "fast lanes" that shipping the water immediately into storm drains. The extra water volume can temporarily overwhelm streams and rivers, causing them to overflow and in all probability result in floods.
