**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.

SURFACE-WATER RECORDS

LOCATION.--Lat 40°53'43", long 74°23'52" referenced to North American Datum of 1983, Boonton Town, Morris County, NJ, Hydrologic Unit 02030103, at dam on Rockaway River, 0.5 mi south of Boonton, and 2.5 mi upstream of Crooked Brook.
DRAINAGE AREA.--119 mi2.
PERIOD OF RECORD.--Continuous-record reservoir station, October 2010 to current year. From 1904 to October 2010, month-end elevation and contents provided by United Water Jersey City.
REVISED RECORDS.--WDR NJ-85-1: 1984, WDR NJ-94-1: 1993.
GAGE.--Water-stage recorder with telemetry. Datum of gage is National Geodetic Vertical Datum of 1929.
COOPERATION.--United Water Jersey City.
REMARKS.--Reservoir is formed by a cyclopean masonry dam with earth wings; dam completed and storage began in 1904. Total capacity at spillway level, 7,620,000,000 gal elevation, 305.25 ft of which 7,366,000,000 gal is usable contents above elevation 259.75 ft, sill of lowest outlet gate. Figures given herein represent usable capacity, prior to 1988 total capacity was published. To adjust usable capacity to total capacity, add 254,000,000 gal. Spillway is topped with two Bascule gates, 2 ft high; prior to 1952, flashboards were used. Flow regulated by Bascule gates, three outlets in gatehouse at head of conduit and by two 48-inch pipes (bottom of sluice pipes at elevation 205 ft). Water is diverted from reservoir for municipal supply of Jersey City. Annual extremes beginning in water year 2014 can be obtained by using this link. Prior to water year 2014, annual extremes can be obtained on the respective annual water year summary.
EXTREMES FOR PERIOD OF RECORD.--Maximum contents, 8,580,000,000 gal, May 12, 1998, elevation, 309.50 ft; minimum, 1,445,000,000 gal, Jan. 31, 1981, elevation 274.71 ft.
