Important information about this monitoring location
LOCATION.-- On left bank, upstream of Floral Drive bridge, 1.9 mi northwest of College Park, and 3.4 mi northeast of Takoma Park. PERIOD OF RECORD.-- October 2007 to current year. GAGE.--Water-stage recorder and crest-stage gage. Datum of gage is 150.41 ft above North American Vertical Datum of 1988. REMARKS.-- Low flow affected at times by slight regulation from unknown source upstream of station. PERIOD OF RECORD (Water Quality).-- SPECIFIC CONDUCTANCE: September 2007 to current year. WATER TEMPERATURE: September 2007 to current year. pH: September 2007 to current year. TURBIDITY: September 2007 to current year. DISSOLVED OXYGEN: September 2007 to current year. REMARKS (Water Quality).-- Turbidity values greater than 1,000 formazin nephelometric 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.
