Earth Gauge: Your Watershed Address
Watersheds are areas of land in which all water drains into a common body of water. Because water does not obey political boundaries, watershed maps can cross county, state and even national lines. The size of a watershed can vary, but all bodies of water have one. You can think of watersheds like pieces of a puzzle; each one is part of a larger watershed “picture.” The Great Lakes-St. Lawrence Watershed covers all or part of seven states and extends into Canada. Anytime a raindrop falls in one of these areas, that raindrop could eventually make its way to one of the Lakes.
