SURFACE-WATER RECORDS
PERIOD OF RECORD - August 1928 to June 1932, October 1943 to current year (October 1953 to April 1955, monthly discharge only).
GAGE - Water-stage recorder with satellite telemetry. Datum of gage is 1,540.13 ft above sea level. Aug. 17, 1928 to June 30, 1932, non-recording gage at present site at datum 1.49 ft higher. Oct. 1, 1943 to Sept. 16, 1974 (Apr. 26 to Dec. 22, 1949, wire-weight gage only), at present site and datum. Sept. 17, 1974 to Nov. 21, 1977, at site 300 ft upstream at present datum.
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 fair to poor except for estimated daily discharges, which are poor, and other periods as noted. Accuracy was affected by the numerous flow changes caused by Loup River Power Canal operations and the extreme shifting of the sand-bed channel.
EXTREMES FOR PERIOD OF RECORD - Maximum discharge, 129,000 ft³/s, August 13, 1966, from rating curve extended above 42,000 ft³/s, on basis of indirect measurement, gage height, 13.93 ft. Maximum gage height, 15.39 ft, March 14, 2019.
