Solving Runoff Problems

Importance of Water Shed

A watershed is a land area that drains rain and other water into a creek, river, lake, wetland, bay or groundwater aquifer. Water from your neighborhood also enters the watershed through the storm drain system and flows directly to local creeks and the Bay without any treatment. It often is contaminated by pollutants that can be toxic to fish, wildlife, and people.
