A watershed is...

"…that area of land, a bounded hydrologic system, within which all living things are inextricably linked by their common water course and where, as humans settled, simple logic demanded that they become part of a community." 

Are you in the Onondaga Lake watershed?

If you live, work, or recreate in the area outlined on this map, you are in the Onondaga Lake watershed.  The Onondaga Lake watershed covers 285 square miles and encompasses two counties, one city, 18 towns, six villages, and the Onondaga Nation Territory.  Surface water and groundwater from precipitation and snowmelt within this region eventually drains or seeps into Onondaga Lake.  The manner in which people use the land in the watershed directly influences the quality of the lake’s water and the health of its ecosystem.  Because of the interconnected nature of a watershed, protection of Onondaga Lake involves all land, lakes, and streams throughout this region.
