> Site Information
LOCATION.--Lat 40°40'48.4", long 73°30'46.8" referenced to North American Datum of 1983, Nassau County, NY, Hydrologic Unit 02030202, on right bank 50 ft east of Wantagh Parkway, 0.4 mi north of Park Avenue, and 0.5 mi northwest of Wantagh.
DRAINAGE AREA.--0.04 mi².  
PERIOD OF RECORD.--September 1937 to March 2000, October 2005 to September 2010, October 2012 to September 2013, October 2015 to current year. Records for November 1955 to September 1971 are unpublished and available in files of the Geological Survey. Prior to October 1957 published as Wantagh Stream at Wantagh.
GAGE.--Since November 1955, daily discharge for 01310000 is calculated based on records for base gage (01309950) and supplementary gage (01309990). Supplementary gage (01309990): Water-stage recorder and concrete control. Datum of gage is 16.96 ft above NGVD of 1929 and 15.79 ft above NAVD of 1988 (VERTCON). Prior to July 28, 1965, at datum 2.00 ft higher. From July 28, 1965 to Oct. 6, 1965, at datum 1.00 ft higher.
REMARKS.--Prior to Nov. 4, 1955, flow at all stages regulated intermittently at outlet of Wantagh Reservoir, 1.0 mi above station, and prior to November 1953 by Browning Pond, 0.5 mi above station. Subsequent to Nov. 3, 1955, permanent diversion of a substantial portion of the flow through west branch of Bellmore Creek. During high flows, streamflow from about 7.8 mi² of Wantagh Creek bypasses the 01309950 gage and contributes to the flow at 01309990. Water Years 2016-21: Records fair except those for estimated daily discharges, which are poor.
EXTREMES FOR PERIOD OF RECORD.--Maximum discharge since Oct. 1, 2015, 240 ft³/s, Sept. 10, 2020, gage height, 3.78 ft; maximum gage height, 3.78 ft, Sept. 10, 2020, Sept. 9, 2021; no flow at times each year 2016-21. Prior to Oct. 1, 2015, maximum and minimum extremes published in records for 01310000 Bellmore Creek at Bellmore, NY.
