Our Virginia Watershed Areas • A watershed can be found almost anywhere. It is defined as the flow of water from a high to low place, over or under land. • Whenever you see a creek, stream, river, delta, lake or ocean you see a part of the watershed.

Agricultural Runoff • Agricultural runoff includes pesticides, animal waste, salts, fertilizers, decomposed food, and trash or plastics used in running the farms or ranches. Urban (city) Runoff • Urban runoff is another leading causes of bad water quality. Water from lawns with fertilizer, trash, oil from cars, factory pollution, or a/c waste absorbs into the ground.

Threats like those produced from agricultural runoff and suburban sprawl are destroying our clean water, the animals and plants that live in or near the water.
