**NOTICE: The New Jersey Water Science Center has transitioned to a new data management software package. While you may not have noticed this transition, some sites may have problems or delays in being updated. We are actively monitoring these conditions and are resolving them as quickly as possible. See the Dec 8 news entry for more information at: https://help.waterdata.usgs.gov/news


ALL DATA ARE AT LOCAL TIME

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.

 


SURFACE-WATER RECORDS

LOCATION.--Lat 40°19'59", long 74°40'55" referenced to North American Datum of 1983, Princeton Township, Mercer County, NJ, Hydrologic Unit 02030105, on right bank, 10 ft downstream from bridge on U.S. Highway 206, 1.6 mi southwest of Princeton, and 4.0 mi upstream from Carnegie Lake.
DRAINAGE AREA.--44.5 mi2.
PERIOD OF RECORD.--October 1953 to current year.
GAGE.--Water-stage recorder with telemetry, crest-stage gage, and concrete control. Datum of gage is 62.23 ft above NGVD of 1929 (levels from New Jersey Geological Survey benchmark).
REMARKS.--Records fair, except for estimated discharges, which are poor. Since July 1959 some regulation by several small reservoirs, combined capacity, 49,800,000 gal. Discharges above 5,100 ft3/s from rating extension on basis of contracted-opening measurement of peak flow.
EXTREMES FOR PERIOD OF RECORD.--Maximum discharge, 10,600 ft3/s, Aug 28, 2011, gage height, 16.23 ft, from rating curve extended above 5,100 ft3/s on basis of contracted-opening measurement of peak flow at gage height 14.26 ft; minimum discharge, 0.0 ft3/s, Aug 5, 1966.
