SURFACE-WATER RECORDS

PERIOD OF RECORD - May 2012 to current year.

GAGE - Water-stage recorder. Datum of gage is 1,119.95 ft above NAVD of 1988. Prior to Nov. 21, 2016, at location 440 ft downstream at different datum.

REMARKS - Water Years 2012-17: Records fair except those for estimated daily discharges and those above 200 ft³/s, which are poor. Water Years 2018-20: Records fair except those for estimated daily discharges, which are poor. Water Years 2021-22: Records fair except those for estimated daily discharges and those above 1,000 ft³/s, which are poor. Water Year 2023: Records poor.

EXTREMES FOR PERIOD OF RECORD - Maximum discharge, 2,900 ft³/s, Dec. 25, 2020, gage height, 8.34 ft, from floodmark, from rating curve extended above 600 ft³/s on basis of contracted-opening, flow-over-road, and flow-through-culvert measurement of peak flow; minimum discharge, 0.36 ft³/s, Sept. 24, 26, 27, 28, 29, 30, 2014, gage height, 1.43 ft; minimum gage height, 0.79 ft, Jan. 15, 2022, result of freezeup.

WATER-QUALITY RECORDS

PERIOD OF DAILY RECORD - SUSPENDED-SEDIMENT DISCHARGE: May 2012 to current year.

REMARKS - Turbidity data are collected every 15 minutes using an in-situ turbidity probe located a 2-inch diameter galvanized steel pipe extending 10 ft from the left bank. Daily suspended-sediment load and concentration are derived from a regression equation relating turbidity to suspended-sediment concentration.

EXTREMES FOR PERIOD OF RECORD - SUSPENDED-SEDIMENT CONCENTRATION: Maximum daily mean, 524 mg/L, Sept. 18, 2012; minimum daily mean, <1 mg/L, on many days in August and September 2014.
