What is a Watershed?
A watershed is an area of land where water flows or drains to the same point. Rainfall and snow melt that isn’t absorbed into the soil (runoff) eventually finds its way to a river, lake or ocean. Our volunteers faithfully track this precipitation, and you can find the results of their efforts on the water data map, as well as data that Lake Monitor and Stream Quality Monitor volunteers record. When water runs off of rooftops, driveways and roads (impervious surfaces), problems like flooding, soil erosion and polluted water may occur. We all need to work together to prevent these problems.
