The National Oceanic and Atmospheric Administration (NOAA) defines a watershed as an area of land that channels rainfall, snowmelt, and runoff into a common body of water. A watershed is also known as a drainage basin. 

Maine is made of up ten watersheds that collect water from rain, runoff, streams, rivers, and tributaries and eventually flows to the Atlantic Ocean.

Why Water Matters

null

As residents of a watershed, we have influence over the health of our resources, from reducing homeowner impact on a local lake to preventing invasive species from entering a stream. As our global clean freshwater sources are becoming more limited, understanding our impacts on our local water systems is even more critical, especially at a young age. Fostering an appreciation for healthy ecosystems and garnering an understanding of how connected our planet is by water resources is at the center of Fresh to Salt: Flowing Together. Fresh and saltwater are all around us in Maine. Many of our industries rely on healthy water which provides environmental and economic value to our communities.
