REMARKS - Gage-height records are generally good. Discharge records are generally fair except for estimated discharges, which are poor. Additional details on the accuracy of the records can be obtained by contacting the USGS South Atlantic Water Science Center at gs-w-ga_nwisweb_data_inquiries@usgs.gov.

Flow regulated by Allatoona Reservoir since 1949. Periods of monthly discharge only are not included in statistics. Statistics prior to regulation are available upon request.
