Green Lake, Manlius

Green Lake is the larger of the two lakes in Green Lakes State Park, which lies about 9 miles east of downtown Syracuse in Onondaga County, New York. Round Lake is the smaller lake located west of Green Lake. Both lakes are meromictic, which means no seasonal mixing of surface and bottom waters occurs. Meromictic lakes are fairly rare; they have been extensively studied, in part because their sediments can preserve a historical record extending back thousands of years, and because of the euxinic conditions which can form in the deep water.
