During October 1991 to September 1995, hydrologic and water-quality data were collected from 47 stations in the Charleston Harbor Estuary and tributary rivers, South Carolina. Both continuous and discrete data were collected. Continuous hydrologic data include stage data recorded at 15- minute intervals from 22 gaging stations. Discrete hydrologic data include tidal-flow measurements made at 10 streamflow stations. Continuous water-quality data include specific conductance, pH, temperature, dissolved oxygen, and calculated salinity data recorded at 15-minute intervals from 19 monitoring stations. Discrete water-quality data include nutrient, biochemical oxygen demand, and suspended- sediment concentrations from 36 sampling stations. Daily maximum, minimum, and mean values are presented for the data from the continuous-stage and water-quality monitors. Dates and times of nutrient, biochemical oxygen demand, and suspended-sediment data collection along with the concentration of each constituent are presented for each water- quality sampling station. Tidal-cycle streamflow measurements are presented in hydrograph and tabular forms.
