SURFACE-WATER RECORDS

LOCATION.--Lat 40°41'15", long 74°18'42" referenced to North American Datum of 1983, Springfield Township, Union County, NJ, Hydrologic Unit 02030104, on left bank 50 ft downstream from bridge on eastbound U.S. Highway 22, 100 ft downstream from Pope Brook, and 1.5 mi south of Springfield.
DRAINAGE AREA.--25.5 mi2.
PERIOD OF RECORD.--July 1938 to current year.
REVISED RECORDS.--WSP 1622: 1945. WDR NJ-1973: 1938(M), 1968(M), 1971(M).
GAGE.--Water-stage recorder with telemetry and crest-stage gage. Datum of gage is 66.17 ft above NGVD of 1929.
REMARKS.--Records fair, except for estimated discharges, which are poor. Discharges above 5,640 ft3/s from rating curve extension on basis of slope-area measurement of peak flow. Water for municipal supply diverted by City of Orange at Orange Reservoir upstream on the West Branch Rahway River. The flow past this station is affected by diversions by pumpage from wells by Orange, South Orange, New Jersey-American Water Company, and Springfield station of Elizabethtown Water Company (deactivated in late 1980s). Since 1980, the site may be affected during high flows by backwater from the Lenape Park flood control dam, about 1 mile downstream.
EXTREMES FOR PERIOD OF RECORD.--Maximum discharge, 8,620 ft3/s, gage height, 10.88 ft, from high-water mark in gage house; minimum discharge, 0.10 ft3/s, Sep 11, 1966.

WATER-QUALITY RECORDS

PERIOD OF RECORD.--Water years 1978 to current year.
REMARKS.--Discrete water-quality data were collected as part of the New Jersey Ambient Surface-Water-Quality Monitoring Network.
