SURFACE-WATER RECORDS
PERIOD OF RECORD - July 1945 to July 1947, October 1976 to current year.
GAGE - Water-stage recorder and crest-stage gage. Datum of gage is 4,107.04 ft above NAVD of 1988. From July 17, 1945, to July 31, 1947, nonrecording gage at site 1,800 ft upstream at different datum. Site 06405000 operated June 1967 to June 13, 1976, at site 500 ft downstream at same 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 good except for estimated discharges, which are poor. Considerable loss occurs to sinkholes downstream from gage and about 50 ft above the gage. Satellite data-collection platform at station.
EXTREMES OUTSIDE PERIOD OF RECORD - Flood of June 10, 1972, reached a stage of 10.35 ft, from floodmarks at site 06405000, 500 ft downstream from current location, discharge of 709 ft³/s from slope-area measurement of peak flow. Flood of June 15, 1976, reached a stage of 10.90 ft, from floodmarks at site 06405000, 500 ft downstream from current location, discharge of 980 ft³/s on basis of slope-area measurement of peak flow.
EXTREMES FOR PERIOD OF RECORD - Maximum discharge, 1,030 ft³/s, from rating curve extended above 709 ft³/s, on basis of slope-area measurement of peak flow, Sept. 7, 1989, gage height, 10.84 ft, from floodmarks; minimum daily discharge, 0.00 ft³/s, June 5, 1977, no flow for some days in 1977, 1988, and 1989.
