What is a Watershed?

A watershed (or basin) is an area of land that drains water, sediment, and dissolved materials to a common receiving body or outlet. We use the term to refer to both to surface and groundwater. Surface water includes rivers, creeks, wetlands. Groundwater is the water underground below the water table.

Where is the Outlet for Cayuga Lake and to where does it Drain?

Cayuga Lake's outlet is at the north end where it drains into the Seneca River, which is part of a larger system known as the Oswego River Basin. This basin carries water from seven of the Finger Lakes, plus other streams and lakes as they drain north into Lake Ontario, one of the five Great Lakes. Together the Great Lakes contain 1/5 of all the world's available fresh water. The health of our watershed is part of what determines the health of this vast and precious fresh water resource.
