REMARKS -

Accuracy of records for water years prior to 2014 are noted in the individual Annual Data Reports for those water years. For water years 2014 onward, records good except for discharges below 10 ft³/s and estimated discharges, which are poor, unless otherwise noted. For the 2019 water year, computed discharges below 10 ft³/s were fair, estimated discharges still poor. For the 2021 water year, computed discharges fair, except for discharges below 10 ft³/s and estimated discharges, which were poor.

EXTREMES FOR PERIOD OF RECORD - Maximum peak flow, 12,600 ft³/s, April 19, 1950, from rating curve extended above 9,000 ft³/s. Maximum peak stage, 20.13 ft, April 19, 1950, site and datum then in use (maximum peak stage, 16.52 ft, present datum).
