Water and nutrient budgets for Cayuga Lake, New York
Studies were undertaken during 1970-71 on the Cayuga Lake watershed to measure the nutrient and water inputs and outputs by geologic and meteorologic vectors for the lake ecosystem. Stream samples collected, with measurements of temperature, electrical conductivity, turbidity, dissolved oxygen, total solids, pH and concentrations of Ca/sup + +/, Mg/sup + +/, Na/sup +/, K/sup +/, NH/sub 4//sup +/, HCO/sub 3//sup -/, Cl/sup -/, SO/sub 4//sup =/, NO/sub 3//sup -/, PO/sub 4/-P, total P and dissolved Si. The chemical concentration in the tributaries varied according to location, watershed use, stream discharge, and season. 91% of the water came into the lake via runoff and 9% fell directly on the lake as precipitation. Some 6.5% of the inorganic nitrogen input, about 3% of the phosphorus and 1.3% of the SO/sub 4//sup =/ entered the lake directly in precipitation. All other inorganic substances were input primarily with runoff. More calcium, magnesium, nitrogen, phosphorus, bicarbonate, and hydrogen ions were added to the lake than were lost through the outlet. More sodium chloride, sulfate, and possibly potassium were lost through the output than were added in runoff and precipitation. The surface loading of both inorganic nitrogen and molybdate reactive phosphorus for Cayuga Lake exceeded or equaled the limits suggested as dangerous for producing undesired effects through cultural entrophication. 61 references, 10 figures, 45 tables.
