USGS Water-Year Summary 2025

01649190 PAINT BRANCH NEAR COLLEGE PARK, MD

LOCATION - Lat 39°02'00.1", long 76°57'50.5" referenced to North American Datum of 1983, Montgomery County, MD, Hydrologic Unit 02070010, on left bank, upstream of Floral Drive bridge, 1.9 mi northwest of College Park, and 3.4 mi northeast of Takoma Park.

DRAINAGE AREA - 13.1 mi².

REVISIONS HISTORY -

WDR-US-2009: 2008(M). WDR-US-2011: 2008-2010.
The gage height for measurement 15S was removed due to application of modern data processing standards on September 1, 2023.
Gage height and discharge for the period February 25, 2013 until October 21, 2021 were revised on December 18, 2024 due to a discrepancy at high stages between the logged data and the verification reads, which led to a change to the stage discharge rating. The gage heights for measurements 44, 52, 54, 73, 79, 91, 93, and 94 were also adjusted.
Gage height and discharge for October 29, 2012 was revised on December 18, 2024 due to a discrepancy at high stages between the logged data and the verification reads.
The discharge for measurement 79 was adjusted to correct for drainage area on December 18, 2024.

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 2022-2024: Records good, except those above 300 ft³/s and those for estimated discharges, which are poor.

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 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.

EXTREMES FOR PERIOD OF DAILY RECORD -

SPECIFIC CONDUCTANCE: Maximum, 13,000 microsiemens per centimeter, multiple occurrences, the first recorded on February 22, 2008; minimum, 15 microsiemens per centimeter, multiple occurrences, the first recorded on August 14, 2011.

WATER TEMPERATURE: Maximum, 28°C, multiple occurrences, the first recorded on July 22, 2011; minimum, -0.4°C, multiple occurrences, the first recorded on February 16, 2016.

pH: Maximum, 10.0 standard units, multiple occurrences, the first recorded on April 28, 2012; minimum, 5.9 standard units, multiple occurrences, the first recorded on September 18, 2018.

TURBIDITY: Maximum, 1,260 formazin nephelometric units (FNU), June 20, 2015; minimum, 0.0 formazin nephelometric units (FNU), multiple occurrences, the first recorded on July, 19, 2021.

DISSOLVED OXYGEN: Maximum, 16.7 milligrams per liter, February 12, 2008; minimum, 6.4 milligrams per liter, multiple occurrences, the first recorded on July 17, 2018.
