referenced to North American Datum of 1983, Franklin Township, Somerset
County, NJ, Hydrologic Unit 02030105, on right bank 1,000 ft downstream
from former Calco Dam and Cuckels Brook, 1,400 ft upstream from bridge
on Interstate 287, 1.2 mi downstream from Millstone River, and 1.2 mi
southwest of Bound Brook.

PERIOD OF RECORD.--
September 1903 to March 1909, October 1944 to
current year. Monthly discharge only for some periods, published in WSP
1302. Prior to October 1966 published as "Raritan River at Bound
Brook" (station 01403000). Records prior to October 1966 are
equivalent to the present records if the effluents from American
Cyanamid Company and Somerset Raritan Valley Sewerage Authority and the
discharge of Cuckels Brook are added.

Water-stage recorder with telemetry. Datum of gage is
NGVD of 1929. Sep 12, 1903 to Mar 31, 1909, non-recording gages at
highway bridge (Queens Bridge), 1.2 mi downstream at different datum.
October 1944 to Sep 30, 1966, water-stage recorder and concrete
control, 1,000 ft upstream at datum 18.06 ft higher.
Records good, except for estimated discharges which
are fair. Water diverted for municipal supply 1.2 mi above station by
New Jersey American Water Company (formerly Elizabethtown Water
Company). Flow regulated by Spruce Run (see 01396790) and Round Valley
Reservoirs. Diversions to and releases from Round Valley Reservoir.
Slight diurnal fluctuations at low flow. Flow includes sewage effluent
from several treatment plants upstream of gage. Discharges above 46,000
/s from rating curve extension on basis of flow-over-dam
computation of peak flow.
