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. --October 1963 to current
year. GAGE. --Water-stage recorder above concrete dam.
Datum of gage is 9.29 ft above NGVD of 1929. Statistical flows
reported for this station are for the full period of record. A
significant quantity of sewage effluent was diverted into a
regional trunk sewer around 1988, thereby reducing streamflows.
This results in current flows appearing to be abnormally low when
compared to long-term statistics. COOPERATION. --Funding for this gage is provided
by the New Jersey Department of Environmental Protection and the
U.S. Geological Survey.
