PERIOD OF RECORD - May 1992 to September 1995, and May 2016 to current year. Seasonal records only.

GAGE - Stage recorder. Datum of gage is 0.10 ft NAVD88. Gage datum consistent through period of record. GOES satellite telemetry at station.

WATER-QUALITY RECORDS

PERIOD OF RECORD -

WATER TEMPERATURE: May 2020 to current year (seasonal).

SPECIFIC CONDUCTANCE: May 2020 to current year (seasonal).

TURBIDITY: May 2020 to current year (seasonal).

PERIOD OF DAILY RECORD -

WATER TEMPERATURE: May 2020 to current year (seasonal).

SPECIFIC CONDUCTANCE: May 2020 to current year (seasonal).

TURBIDITY: May 2020 to current year (seasonal).

INSTRUMENTATION - Site monitor recording; water temperature, specific conductance, and turbidity, at 15-minute interval. Water temperature, specific conductance, and turbidity are seasonal. Data is transmitted via GOES satellite.

REMARKS -

WATER TEMPERATURE: Record represents water temperature at sensor within 0.2°C.

SPECIFIC CONDUCTANCE: Record represents specific conductance at sensor within 5 µs/cm or 3% of the measured value, whichever is greater.

TURBIDITY: Record represents turbidity at sensor within 0.5 turbidity units or 5% of the measured value, whichever is greater.

EXTREMES FOR PERIOD OF RECORD -

WATER TEMPERATURE: Maximum observed 1.7°C, June 03, 2022 and multiple days in June 2023. Minimum observed 0.0°C October 25, 2022 and multiple days in August and September 2023.

SPECIFIC CONDUCTANCE: Maximum observed 325 µs/cm, May 26, 2023. Minimum observed 85 µs/cm, August 19, 2020.

TURBIDITY: Maximum observed 1390 FNU July 11, 2023 (actual value know to be greater than reported value) . Minimum observed 0.0 FNU multiple days during May 2023.
