**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 39°54'11", long 75°01'17" referenced to North American Datum of 1983, Cherry Hill Township, Camden County, NJ, Hydrologic Unit 02040202, on right bank just upstream of dam on Wallworth Lake in Pennypacker Park, 200 ft upstream from bridge on State Highway 41 (Kings Highway) in Haddonfield, 0.6 mi upstream from North Branch Cooper River, and 7.7 mi upstream from mouth.
DRAINAGE AREA.--17.0 mi2.
PERIOD OF RECORD.--Continuous-record discharge station, October 1963 to current year.
REVISED RECORDS.--WDR NJ-1969: 1967(M). WDR NJ-82-2: Drainage area. WDR NJ-04-1: 1971(M).
GAGE.--Water-stage recorder with telemetry above concrete dam. Datum of gage is 9.29 ft above NGVD of 1929.
REMARKS.--Records fair, except for estimated discharges and discharges below 20 ft3/s, which are poor. Bypass gates were installed on both sides of the dam in August 1987. Occasional regulation at low-flow from small lakes upstream. Small wastewater treatment plants in the basin were regionalized after the summer of 1987, significantly reducing low-flow.
EXTREMES FOR PERIOD OF RECORD.--Maximum discharge, 3,300 ft3/s, Jul 13, 2004, gage height, 6.27 ft; minimum discharge, 0.80 ft3/s, Nov 13, 1972, regulation from unknown source.

WATER-QUALITY RECORDS

PERIOD OF RECORD.--Water years 1968-79, 1991 to current year.
PERIOD OF DAILY RECORD.--SUSPENDED-SEDIMENT DISCHARGE: March 1968 to September 1969.
WATER TEMPERATURE: March 1968 to August 1969, recorded once daily; October 1998 to September 2001, recorded hourly.
REMARKS.--Discrete water-quality data were collected as part of the New Jersey Ambient Surface-Water-Quality Monitoring Network.
