Duration Graphs for Selected North Carolina StationsDuration 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. ATTENTION -- As of January 28, 2009, the standard Duration graphs are temporarily unavailable due to software upgrades. The problem is being addressed. In the meantime, the USGS WaterWatch page provides simple streamflow duration hydrographs, which are linked below by station. Thank you for your patience and understanding while these software issues are being resolved. Explanation of Duration Graphs To view a graph, select a station from the map shown below or from the following table.
