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 those for June 15 - 30, 2014, May 11 to June 14, 2015, Aug. 12 - 17, 2016, and June 9 to Oct. 19, 2020, which are fair and those for estimated discharges, which are poor. Satellite data-collection platform at station.
EXTREMES FOR PERIOD OF RECORD - Lowest annual mean, 0.00 ft³/s, occurred in 1959, 1988, and 1990. Minimum daily discharge, 0.00 ft³/s, Oct. 1, 1956, no flow for long periods in most years.
