The excess water volume can quickly overwhelm streams and rivers, causing them to overflow and possibly result in floods. These surfaces act as "fast lanes" that transport the water directly into storm drains. During periods of heavy rain and snowfall, water may run onto and off of impervious surfaces such as parking lots, roads, buildings, and other structures because it has nowhere else to go. Rain and snowmelt from watersheds travel via many routes to the sea. Instead, it quickly runs off to lower ground. In other areas, where the soil contains a lot of hard clay, very little water may infiltrate. Some water infiltrates much deeper, into underground reservoirs called aquifers. This groundwater remains in the soil, where it will eventually seep into the nearest stream.
When rain falls on dry ground, it can soak into, or infiltrate, the ground. Not all water flows directly to the sea, however. As the water flows, it often picks up pollutants, which may have sinister effects on the ecology of the watershed and, ultimately, on the reservoir, bay, or ocean where it ends up. Water from hundreds, and often thousands, of creeks and streams flow from higher ground to rivers that eventually wind up in a larger waterbody. an event marking a unique or important historical change of course or one on which important developments depend.

(psychology) stress at which a person breaks down or a situation becomes crucial. It acts a lot like a thesaurus except that it allows you to search with a definition, rather than a single word. states and two Canadian provinces stretching from the Rockies to the Appalachians! a crisis situation or point in time when a critical decision must be made. The entire region draining into a river, river system, or other body of water: a list of reptiles found in the watershed. The largest watershed in the United States is the Mississippi River Watershed, which drains 1.15 million square miles (2,981,076 square kilometers) from all or parts of 31 U.S. Water from as far away as upstate New York eventually finds its way to the Chesapeake-the nation’s largest estuary.Ĭonversely, some watersheds encompass thousands of square miles and may contain streams, rivers, lakes, reservoirs, and underlying groundwater that are hundreds of miles inland. The Chesapeake Bay watershed is home to 18 million people and covers 64,000 square miles (165,759 square kilometers).
