**NOTICE: The New Jersey Water Science Center has transitioned to a new data management software package. While you may not have noticed this transition, some sites may have problems or delays in being updated. We are actively monitoring these conditions and are resolving them as quickly as possible. See the Dec 8 news entry for more information at: https://help.waterdata.usgs.gov/news

During winter months, cold and ice may result in inaccurate real-time gage height and streamflow data. Adjustments or deletions of this data can only be done after detailed analysis.

 


SURFACE-WATER RECORDS

LOCATION.--Lat 40°43'39", long 74°43'49" referenced to North American Datum of 1983, Washington Township, Morris County, NJ, Hydrologic Unit 02030105, on right bank 1.1 mi upstream from bridge on County Highway 512 (Black River Road), 1.2 mi northwest of Pottersville, and 5.5 mi upstream from Cold Brook.
DRAINAGE AREA.--32.8 mi2.
PERIOD OF RECORD.--Continuous-record discharge station December 1921 to current year. Monthly discharges October and November 1921 published in WSP 1302. Prior to October 1952, published as "Black River near Pottersville".
REVISED RECORDS.--WSP 741: 1932. WSP 781: Drainage area. WSP 1552: 1922, 1924-29(M), 1931(M), 1933-34(M), 1938(P), 1939(M), 1940, 1941(M), 1942-46(P), 1947(M), 1948-49(P), 1951-52(P), 1953(M). WDR NJ-80-1: Correction 1979(P).
