Important information about this monitoring location

LOCATION.-- On right bank, 0.10 mi downstream from highway bridge at Trimble Road and 0.95 mi upstream from mouth. PERIOD OF RECORD.-- September 2015 to current year. GAGE.-- Water stage recorder and crest-stage gage. Datum of gage is 0.26 ft above North American Vertical Datum of 1988. REMARKS.--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.
