What is a watershed?

A watershed area of land that is drained by a river. Melting snow and rain can affect and dramatically increase the amount of water in a watershed but, other points can leave the watershed practically empty. Additionally, communities that depend on these rivers for water are highly affected

What is the Columbia Watershed?

The Columbia’s watershed is very large and covers seven states as well as a Canadian province. The starting point in the North is found in the glaciers of the Canadian Rockies. The main body of the Columbia Rivers goes on for a thousand miles until it hits the Pacific. As the river flows south and west, it is supplied by several other rivers on the way to the Pacific. The Columbia River is responsible for forming the state border between Washington and Oregon. The largest river that connects with the Columbia is the Snake River. The Columbia Watershed covers a large area that can be compared to the size of France.

Why Is Columbia Watershed Important?

The Columbia Watershed is important because it provides urban development, agriculture, transportation, recreation, fisheries and hydropower for its area. They help sustain life because they supply water for people to use. The watershed also gets a great amount of precipitation that provides for its seasonal supply of water. The watershed is known for its extensive amount of aquifers under the ground

Columbia Watershed Pollution and Depletion

In order to keep the water of Columbia clean and pure, the Columbia Watershed Management plan was put into action. The plan uses two distinct approaches. The first identifies and restores the watershed by locating the sources of the pollution and constructing restoration projects in an attempt to get rid of the source. The second is educating and involving residents and property owners in watershed stewardship.
