What is a watershed? A watershed (or drainage basin) is an area of land that drains all of its waters through a network of streams and rivers into larger bodies of water. Everybody lives in a watershed because every part of the earth catches some form of water.
What is a Watershed? An area of land, from ridge top to ridge top, that collects, stores, and releases water to a common point, such as a river or a lake
What’s in a Watershed? Streams Rivers Lakes Wetlands Hills Mountains Farms Cities Houses Humans Animals Plants
Watersheds are separated by ridges of high ground called divides. What separates one watershed from another watershed? Every watershed is bounded by divides. Different streams or rivers empty each watershed.
Every drop of water that touches the surface of the ground does one of three things …
1.It evaporates. Evaporation puts water back into the atmosphere to again become rain or snow. Every drop of water that touches the surface of the ground does one of three things … (cont’d) 2.It soaks into the ground. Once it soaks into the ground, it becomes groundwater, also known as an aquifer. 3.It runs downhill along the ground. This is surface water, which makes its way into streams, rivers, ponds, lakes, and eventually, into the ocean.
