The study was conducted to appraise the trophic status of the saline Onondaga Lake, Onondaga County, New York, and to estimate the effects of the proposed waste treatment plant. The determined parameters included circulation patterns, distribution of chemical constituents, and the biotic contents of the lake. Mineral-water equilibria showed an uninterrupted and a widely distributed formation of phosphate-bearing minerals. The predominant component of lake sediments is calcium. The salinity of lake water did not preclude occurrence of a wide variety of phytoplankton, zooplankton, and fish. Proposed waste treatments should significantly increase the supply of dissolved oxygen and lower the phosphorus concentration.
