DRAINAGE AREA - 13.1 mi².

REVISIONS HISTORY - WDR-US-2009: 2008(M). WDR-US-2011: 2008-2010.

SURFACE-WATER RECORDS

PERIOD OF RECORD - October 2007 to current year.

GAGE - Water-stage recorder and crest-stage gage. Datum of gage is 150.57 ft above North American Vertical Datum of 1988.

REMARKS -

Water Years 2020-2021: Records poor, including those for estimated discharges.

Water Years 2017-2019: Records fair, except those for estimated discharges, which are poor.

Water Year 2016: Records good, except those for estimated daily discharges, which are poor.

Water Year 2015: Records good, except those for the period October 1–December 2, which are fair, and those for estimated daily discharges, which are poor.

Water Year 2014: Records fair, except those for estimated daily discharges, which are poor.

Water Year 2013 and prior years’ accuracy statements can be found in Annual Water Data Reports.

U.S. Geological Survey gage-height telemeter at station. Low flow affected at times by slight regulation from unknown source upstream of station.

WATER-QUALITY RECORDS

PERIOD OF DAILY RECORD - 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.

COOPERATION - Funding for water-quality data collection is provided by the Montgomery County Department of Environmental Protection and the U.S. Geological Survey.

INSTRUMENTATION - Water-quality monitor September 2007 to current year.

REMARKS - Turbidity values greater than 1,000 formazin nepthelometric units (FNU) exceed the instrument calibration range. Values are included in the record but are presumed to have lower precision. Missing record due to periodic instrument malfunction.
