Green Lake (New York)
From Wikipedia, the free encyclopedia
Green Lake is the larger of the two lakes in Green Lakes State Park just east of Syracuse in Onondaga County, New York. (Round Lake is the smaller one.) Both are meromictic lakes, which means that there is no autumn and spring mixing of surface and bottom waters. Such lakes have a high potential for evidence of ancient plant and animal life. The color of the lake is not, in fact, green. Because of its depth (192 feet) and small size (150 acres), and relative protection from the wind, the water layers in this lake do not mix or turn over.
Interesting features in the lake are "marl reefs", reef-like formations along the shoreline, consisting of bacteria-bound marl.
