National Weather Service flood stage for this gage is 28.0 ft.
Forecasts for this gage are issued by the National
Weather Service routinely year-round.
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 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.
GAGE.--Water-stage recorder. Datum of gage is NGVD of 1929. Sept. 12, 1903 to Mar. 31, 1909, nonrecording gages at highway bridge, 1.2 mi downstream at different datum. October 1944 to Sept. 30, 1966, water-stage recorder and concrete control at site 1,000 ft upstream at datum 18.06 ft higher. Flow is affected by storage in reservoirs, water-supply diversions, and sewage effluent inflow.
