USGS Water-Year Summary 2024

01651003 NORTHWEST BRANCH ANACOSTIA AT BRENTWOOD, MD

LOCATION - Lat 38°56'56.3", long 76°57'22.4" referenced to North American Datum of 1983, Prince George's County, MD, Hydrologic Unit 02070010, on right bank, 200 feet downstream from bridge on 38th Street, 0.3 miles north of Brentwood, 0.75 miles upstream from confluence with Northeast Branch Anacostia River, and 1.5 miles downstream from Sligo Creek.

DRAINAGE AREA - 51.3 mi². 51.3 mi².

SURFACE-WATER RECORDS

PERIOD OF RECORD - May 2023 to current year.

GAGE - Water-stage recorder. Datum of gage is 3.60 ft above North American Vertical Datum of 1988.

REMARKS -

Water Years 2023-2024: Records fair, except those above 300 ft³/s and those for estimated discharges, which are poor.

Prior to June 1961, low flow regulated by storage at Burnt Mills Dam, 7.0 mi upstream from station. Inflow pumped from Patuxent River to augment water supply for Washington Suburban Sanitary District, August 1939 to August 1960. Small diversion since 1962 for irrigation of golf courses upstream from station. US Geological Survey satellite data-collection platform at station.

WATER-QUALITY RECORDS

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.
