Water-quality data for selected North Carolina streams and reservoirs in the Triangle Area Water Supply Monitoring Project, 1988-92
The Triangle Area Water Supply Monitoring Project was developed to assess regional water-quality characteristics in drinking-water supplies and to provide a basis for determining trends in water quality for the Research Triangle area, which is one of the fastest growing areas in North Carolina. The study area is in the upper Neuse River Basin and the upper Cape Fear River Basin in the north-central Piedmont Province of the State. Hydrologic data were collected at 21 reservoir sites and 30 stream sites from October 1988 through September 1992 to define water-quality characteristics. The data collected at these sites include streamflow data and approximately 275 physical properties and chemical characteristics of surface water.

Water-quality data from continuously monitored sites in the Pamlico and Neuse River estuaries, North Carolina, 1990-91
Water quality measurements were made at six sites in or near North Carolina's Pamlico River estuary and at five sites in or near the Neuse River estuary. Measurements taken at 15-minute intervals included near-surface and near-bottom specific conductance; near-surface water temperature; and near-surface, mid-depth, and near-bottom dissolved-oxygen concentrations. In the Pamlico River estuary, salinities generally ranged from near zero to about 20 parts per thousand during the period April 1989 through September 1991; however, unnaturally high salinities (up to about 51 parts per thousand) were observed at one site on July 11, 1990. Recorded water temperatures in the Pamlico River were between 0 and 33 degrees Celsius during the measurement period. Dissolved-oxygen concentrations ranged from less than 1 to 20 milligrams per liter. In the Neuse River estuary, salinities ranged from less than 0.1 to nearly 33 parts per thousand between May 1989 and September 1991. During the same period, recorded water temperatures in this estuary were between 0 and 33 degrees Celsius. Dissolved-oxygen concentrations ranged from less than 1 to 21 milligrams per liter. Instantaneous values for selected periods are summarized in a series of box plots. Daily mean values of salinity, water temperature, dissolved-oxygen concentrations, and dissolved oxygen, percent saturation, are presented in tables and graphs, as are 5-day mean values for day and night conditions. This is the second in a series of reports summarizing water quality data obtained from these continuously monitored sites.

Water-quality data from continuously monitored sites in the Pamlico and Neuse River estuaries, North Carolina, 1989-90
Beginning in April 1989, water quality measurements were made at six sites in or near Pamlico River estuary and at five sites in or near the Neuse River estuary. Measurements taken at 15-minute intervals included near-surface and near-bottom specific conductance; near-surface water temperature; and near-surface, mid-depth, and near-bottom dissolved-oxygen concentrations. Water-quality data obtained from continuously-monitored sites in the Pamlico River estuary and the Neuse River estuary are presented for the period April 1989 through September 1990. Instantaneous values for selected periods are summarized in a series of box plots. Instantaneous maximum and minimum values are also tabulated. Daily mean values of salinity, water temperature, and dissolved-oxygen concentrations for the entire period are presented in tables and graphs.
