Important information about this monitoring location

LOCATION.-- On left bank, downstream side of Pearre Road bridge, 300 ft south of McKinstrys Mill. PERIOD OF RECORD.-- November 2024 to current year. GAGE.-- Water-stage recorder and crest-stage gage. Datum of gage is 429.53 ft above North American Vertical Datum of 1988. REMARKS (Water Quality).-- Turbidity values greater than 1,000 formazin nepthelometric units (FNU) exceed the instrument calibration range. Values above 1,000 FNU are included in the record but are presumed to have lower accuracy. The accuracy limit of the turbidity sensor in low turbidity water is +/- 0.3 FNU. October 1, 2024: Values are censored and qualified as Less Than 0.3 FNU if they are recorded below 0.3 FNU.
