Lat 40°40'30", long 74°13'19"
referenced to North American Datum of 1983, Hillside Township, Union
County, NJ, Hydrologic Unit 02030104, on left bank at Ursino Lake Dam
in Elizabeth, 75 ft upstream from bridge on Trotters Lane and 3.8 mi
upstream from mouth.
PERIOD OF RECORD.--
October 1921 to current year. Peak discharges
from October 1922 through December 27, 1972, published as Elizabeth
River at Elizabeth, NJ (station 01393500), located 85 ft upstream of
bridge on Westfield Avenue, and 2,800 ft downstream of present gage,
are considered equivalent at medium and high flows.
WSP 1552: Drainage area, 1922-23, 1927-29(M),
1932, 1933-34(M), 1938(P), 1942(M) 1944(P), 1945(M), 1948(P),

Water-stage recorder with telemetry, crest-stage gage,
and two concrete weirs. The right concrete weir was lowered 5 ft on Dec
18, 1985. Datum of gage is NGVD of 1929 (levels by Corps of Engineers).
Prior to Oct 1, 1922, non-recording gage at site 2,800 ft downstream at
datum 4.14 ft higher and Oct 1, 1922 to May 18, 1923, at same site at
datum 5.23 ft higher. May 19, 1923 to Dec 27, 1972, at site 2,800 ft
downstream at datum 5.23 ft higher and published as "Elizabeth
River at Elizabeth" (station 01393500), drainage area 18.0
Records good, except for discharges above 500
/s and estimated discharges, which are fair. Discharges
above 1,400 ft3
/s from rating curve extension on basis of
theoretical rating. Diversion by pumpage from Hammock Well Field in
Union Township for municipal supply by New Jersey American Water
Company (formerly Elizabethtown Water Company) probably reduces the
flow past the station. Elizabethtown Water Company diverted water for
municipal supply from Ursino Lake in Elizabeth prior to 1929.
