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 41°01'29", long 74°24'30" referenced to North American Datum of 1983, West Milford Township, Passaic County, NJ, Hydrologic Unit 02030103, on left bank 15 ft downstream from culvert under southbound lane of State Route 23, 900 ft upstream of Macopin Reservoir, 0.5 mi southeast of Green Pond Junction, and 0.8 mi east of Charlotteburg Reservoir.
DRAINAGE AREA.--57.1 mi².
PERIOD OF RECORD.--Continuous-record gaging station, April 2010 to current year.
GAGE.--Water-stage recorder with telemetry. Datum of gage is 610 ft NAVD 1988 (from topographic map).
REMARKS.--Records fair, except for estimated discharges, which are poor. Flow regulated by Cannistear Reservoir, Oak Ridge Reservoir, Clinton Reservoir, Charlotteburg Reservoir, and other small upstream lakes and ponds. Water diverted at Charlotteburg Reservoir for municipal supply of city of Newark. Discharges above 940 ft³/s from rating curve extension on basis of culvert computation of peak flow.
EXTREMES FOR PERIOD OF RECORD.--Maximum discharge, 3,650 ft³/s, Aug 28, 2011, gage height, 11.09 ft, from rating curve extended above 940 ft³/s on basis of culvert computation of peak flow; minimum discharge, 1.4 ft³/s, Aug 27, 2010.
