Peak Streamflow for North Carolina
Questions about data? Click here.
Operation of the following gaging stations will discontinue on October 1, 2023 after funding ends. Questions regarding extending the operation beyond October 1st can be directed to the South Atlantic Water Science Center North Carolina Associate Director of Data Curtis Weaver (firstname.lastname@example.org, 984-220-5849).
The daily maximum and minimum water level values for groundwater wells after September 30, 2023 are no longer being displayed on NWISWeb. However, these values can be determined using the instantaneous values that are available through the "Time-Series: Current/Historical Observations" option in the available data dropdown box for the station.
This section provides for the display of annual peak streamflow values for both continuous and partial-record gaging stations. Annual peak flow values are the maximum instantaneous streamflow values recorded at a particular site for the entire water year from October 1 to September 30.
A note of caution that the annual peak flow value may not occur at the same time the maximum water level occurs due to conditions such as backwater, tidal fluctuations, etc.
The following codes are used to indicate special conditions that affect how the peak streamflow value may be interpreted
Peak flow data for gaging stations can be selected as follows:
