USGS 01403060 Raritan River below Calco Dam at Bound Brook NJ


Click to hidestation-specific text
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.



LOCATION.--Lat 40°33'04", long 74°32'54" 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.
DRAINAGE AREA.--785 mi2 of which 11 mi2 probably is noncontributing, draining into the Delaware and Raritan Canal.
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.
REVISED RECORDS.--WSP 1552: 1903-07, 1946(M), 1949, 1952(P).
GAGE.--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.
REMARKS.--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. Several measurements of water temperature were made during the year.
EXTREMES FOR PERIOD OF RECORD.--Maximum discharge, 82,900 ft3/s, September 17, 1999, gage height, 42.13 ft, from high-water-mark in gage house, from rating curve extended above 46,000 ft3/s, on basis of flow-over-dam computation of peak flow at Fieldville Dam; minimum discharge, 26 ft3/s December 31, 2001.
FOOTNOTES.--MAXIMUM PEAK FLOW:COLUMN4:VALUE:a From rating extended above 46,000 ft3/s on basis of indirect computation of peak flow downstream at Fieldville Dam. MAXIMUM PEAK STAGE:COLUMN4:VALUE:b From floodmark in gage house.
