Abstract

Seventeen Ohio lakes were evaluated in 1975 for water quality status. Spring and late summer data included physical and profile measurements for a broad spectrum of chemical and biological constituents. Secchi disk transparency ranged from 0.1 to 2.9 meters. Thermal stratification or stability is shown for 10 lakes deeper than 4.6 meters. Anaerobic conditions, and high concentrations of ammonia, carbon dioxide, and hydrogen sulfide, developed in all thermally stabilized lakes. Maximum dissolved oxygen was measured at 20.8 milligrams per liter (229 percent saturation) in Paint Creek Lake. Calcium was the dominant and (or) co-dominant cation and bicarbonate and (or) sulfate the dominant anions in all lakes sampled. Two lakes, Hope and Vesuvius, had soft water. Specific conductance ranged from 128 to 510 micromhos. Pesticides were not detected except in Action Lake, and concentrations of one or more trace metals were above State limits in 10 lakes. Fecal coliform counts were generally low and exceeded 400 colonies per 100 milliliters in four lakes during runoff events. Blue-green algae dominated the summer phytoplankton communities in 16 lakes, with maximum densities greater than two million cells per milliliter. (Woodard-USGS)
