Watersheds

A watershed  is the area of land where all of the water that is under it or drains off of it goes into the same place. Being just north of Dallas, Texas, I live in the Trinity River watershed. It's important to monitor the quality of our local watershed because harmful pollutants can be washed into our freshwater from point, able to see the source of it, and nonpoint pollution, pollution that can't be traced back to single source. The benefits of watersheds include improved water quality, habitat protection, and groundwater recharge.
