CLOSE What is a Watershed?

Watershed boundaryA watershed is the area of land that drains to a common lake, wetland, stream or river. Watersheds come in different sizes and scales.

For example, someone who lives on Lake Minnetonka is part of the Lake Minnetonka watershed. Because Lake Minnetonka connects to the Minnehaha Creek, that property is also part of the Minnehaha Creek Watershed, which flows into the Mississippi River Watershed. As such, the property is also in the Gulf of Mexico Watershed.

CLOSE What is Runoff?

Storm DrainRunoff is the water that flows over the surface of the land or a building or road downstream to a lake, wetland or stream.

Before the land was altered, much of the water that fell on it soaked directly into the ground. Water was then used by vegetation, recharged stores of ground water, or was discharged to lakes, wetlands and streams. As we farmed the land and built our cities we re-routed runoff via ditches, stormwater pipes and culverts directly to local lakes, wetlands and streams. As a result, we are overwhelming many of our water bodies today.
