“Water runs downhill” and a watershed is a land area whose runoff drains into any stream, river, lake and ocean. All land is part of a watershed and we all live in a watershed.
We, as humans along with plant and animal life depend on the watershed and influence it in some way.As water flows downhill in small to progressively larger streams and rivers, it moves over land and provides water for urban, agricultural and environmental needs. The watershed community is made up of everyone who lives there plus all other plant and animal life.
A watershed collects water from rainfall, it stores water of various amounts, it releases water as runoff, it provides diverse sites for chemical reactions to take place and it also provides habitat for floral and fauna.
Human activities affect all of the functions of a watershed. It is up to us to improve and protect our watersheds for the generations to come.
