Water-Quality Characteristics of Inflow to and Outflow from Falls Lake, NorthCarolina, 1982-87

摘要

The report describes the water-quality characteristics of streams flowing intoand out of Falls Lake for the period October 1982 through June 1987. Hydrologic data collection included measurements of streamflow, physical characteristics such as dissolved-oxygen concentrations, water temperature, pH, suspended-sediment concentrations, and specific conductance, and concentrations of major dissolved constituents, nutrients, and selected minor elements. The study was designed to allow for comparisons of the physical and chemical constituents of the inflow from major tributaries to Falls Lake and those of the outflow, and for comparisons with background water-quality characteristics of streams in relatively undeveloped basins. Estimated annual nitrogen and phosphorus loads and yields into and out of Falls Lake were also determined.
