Otsego Lake (Otsego County, NY), of glacial origin, fonns the headwaters of the Susquehanna River. It is a deep (50.5 m max) dimictic waterbody of4,167 acres having a catchment of46,482 acres. The lake serves as the potable water supply for the Village of Cooperstown and it is noted for its cold water fishery, which includes native lake trout and whitefish as well as stocked brown trout and Atlantic salmon. Otsego provides many recreational opportunities and also serves as an aesthetic backdrop for the historically preserved Village, which depends heavily upon a tourist-based economy (Harman et at., 1997).
