Owasco Lake
Reservoir Central New York lake, part of the Finger Lakes
One of New York’s Finger Lakes, Owasco Lake offers boating, fishing, shoreline trails and nearby small towns; visitors combine lake activities with regional wineries and historic Auburn.
Owasco Lake is one of the Finger Lakes in central New York, located in Cayuga County immediately south of the city of Auburn. It is a long, narrow glacial lake typical of the Finger Lakes region.
The lake is used for recreation including boating and fishing, and supports local shoreline communities and small marinas. Water quality and shoreline management are important local concerns because of residential development and agricultural land in the watershed.
Formed by glacial carving during the last Ice Age, the basin has the steep-sided shape characteristic of Finger Lakes. Over time the lakeshore has been developed with homes, parks, and small harbors concentrated at the lake’s ends.
Geographically the lake sits in central New York’s Finger Lakes district, with the city of Auburn immediately to its north and rural landscapes on its flanks.
