Your environment - the land, river, streams and lakes - all work together to process, filter and otherwise manage rainwater. Over time, these areas can be polluted, erode, or otherwise fill with sediment or other materials, causing both short and long-term problems in the environment. Find where you live and see which stream, rivers and watersheds are impaired or damaged.

What is an watershed?

A 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. The word watershed is sometimes used interchangeably with drainage basin or catchment. Ridges and hills that separate two watersheds are called the drainage divide. The watershed consists of surface water--lakes, streams, reservoirs, and wetlands--and all the underlying ground water. Larger watersheds contain many smaller watersheds. It all depends on the outflow point; all of the land that drains water to the outflow point is the watershed for that outflow location. Watersheds are important because the streamflow and the water quality of a river are affected by things, human-induced or not, happening in the land area "above" the river-outflow point.
