For 2014 water year, records fair. For 2015 water year, records fair. For 2016 water year, records fair, discharges above 17,000 ft³/s are not computed.

For 2019 water year, records good to poor, discharges above 17,000 ft³/s are not computed.
EXTREMES FOR PERIOD OF RECORD - Flow regulated by Thurmond Lake and by other powerplants above station. Discharge represents only that portion of the flow confined to the main channel; less than about 17,000 ft³/s. At times of high flow, bankfull capacity is exceeded in the intervening channel reach, therefore, daily mean discharges greater than 17,000 ft³/s are not shown.
