    National Weather Service flood stage for this gage is 20.0 ft.

    Forecasts for this gage are issued by the National Weather Service routinely year-round.
    Forecast information is available here.


    gage photo LOCATION.--Lat 40°13'18", long 74°46'41" referenced to North American Datum of 1983, Trenton City, Mercer County, NJ, Hydrologic Unit 02040105, on left bank 450 ft upstream from Calhoun Street Bridge at Trenton, 0.5 mi upstream from Assunpink Creek, 0.9 mi north of Morrisville, PA, and at river mile 134.5.
    DRAINAGE AREA.--6,780 mi2.
    PERIOD OF RECORD.--February 1913 to current year. October 1912 to February 1913 monthly discharge only, published in WSP 1302. Gage-height records collected in this vicinity since 1904 are contained in reports of the National Weather Service.
    GAGE.--Water-stage recorder. Datum of gage is 0.00 ft NGVD of 1929, and determined to be approximately -1.05 ft below NAVD of 1988 through the use of Vertcon. Prior to Sep 30, 1965, at datum 7.77 ft higher. Feb 24, 1913 to Oct 2, 1928, nonrecording gage on downstream side of highway bridge at site 450 ft downstream.
    EXTREMES OUTSIDE PERIOD OF RECORD.--Flood of Oct 11, 1903 reached an elevation of about 28.5 ft above NGVD of 1929, discharge, estimated at 295,000 ft3/s. Maximum elevation known, 30.6 ft above NGVD of 1929, Mar 8, 1904 (from floodmark; due to ice jam).
    COOPERATION.--Funding for this gage is provided by the Delaware River Basin Commission, the U.S. Army Corps of Engineers, Philadelphia District and the U.S. Geological Survey.
