Precipitation, streamflow, and water-quality data from selected sites in the City of Charlotte and Mecklenburg County, North Carolina, 1995-97

Precipitation data were collected at 46 precipitation sites and 3 atmospheric deposition sites, and hydrologic data were collected at 9 stream sites in the vicinity of Charlotte and Mecklenburg County, North Carolina, from July 1995 through June 1997. Data were collected to identify the type, concentration, and amount of nonpoint-source stormwater runoff within the area. The data collected include measurements of precipitation; streamflow; physical characteristics, such as water temperature, pH, specific conductance, biochemical oxygen demand, oil and grease, and suspended sediment concentrations; and concentrations of nutrients, metals and minor constituents, and organic compounds.

These data should provide valuable information needed for (1) planned watershed simulation models, (2) estimates of nonpoint-source constituent loadings to the Catawba River, and (3) characterization of water quality in relation to basin conditions. Streamflow and rainfall data have been used to provide early warning of possible flooding.
