Duration Graphs for Selected North Carolina Stations

Duration graphs characterize the state of the hydrology of a stream with respect to time. To quantify the state of the hydrology for the current year, the current running 7-day average flows are compared to selected non-exceedance percentiles computed for each day of the year over the history of the gaging station.

Explanation of Duration Graphs

To view a graph, select a station from the map shown below or from the following table.
