REMARKS.--Records fair except those for periods of backwater from the Ohio River, Jan. 13 to Feb. 21, Mar. 6-26, and Apr. 23 to May 15, and those for estimated daily discharges, which are poor. Flow of lower part of Cache River Basin was diverted from Ohio River to Mississippi River beginning Oct. 31, 1950, through diversion channel of Mounds-Mound City flood-protection project. Flow of upper part of Cache River Basin, including flow past this station, continued to discharge to Ohio River, passing through Post Creek cutoff directly to Ohio River instead of through the original channel of Cache River. Gage-height telemeter at station.
