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°53'40", long 74°15'58" referenced to North American Datum of 1983, WAYNE TOWNSHIP, Passaic County, NJ, Hydrologic Unit 02030103, on upstream left bank at bridge on Interstate 80, 300 ft upstream from confluence with Singac Brook, 0.4 mi downstream from confluence with Pompton River, and 1.5 mi northwest of Singac.
DRAINAGE AREA.--740 mi².
PERIOD OF RECORD.--Continuous-record discharge station December 2012 to current year.
GAGE.--Water-stage and velocity recorder, with telemetry. Datum of gage is 155.00 ft above NGVD of 1929.
REMARKS.--Records fair, except for estimated discharges, which are poor. Flow regulated by reservoirs in Rockaway (see 01379990 and 01380900), Pequannock (see 01382100, 01382200, 01382300, 01382380, and 01382400), Wanaque (see 01383000, 01384002, and 01386990), and Ramapo River subbasins. Large diversions for municipal supply from Passaic River above Beatties Dam (see 01389490), and from Rockaway (see 01380800), Pequannock (see 01382370), Pompton (see 01388980, 01388981, 01388982), Ramapo (see 01387990), and Wanaque (see 01386980) Rivers. In addition, the New Jersey-American Water Company (formerly Commonwealth Water Company) diverts from Canoe Brook near Summit (see 01379529) and from Passaic River near Summit (see 01379510). New Jersey-American Water Company, the city of East Orange, and others also divert water for municipal supply by pumping wells in the basin. Flow includes sewage effluent from several treatment plants upstream of gage. Flows exclude inflow from the Signac Brook 200 ft downstream.
EXTREMES FOR PERIOD OF RECORD.--Maximum discharge, 8,100 ft³/s, May 3, 2014, gage height, 9.65 ft; minimum discharge not determined.

National Weather Service flood stage for this gage is 8.5 ft.

The water temperature data for this station are temporary and will only be displayed for 120 days. Although the instrumentation is calibrated at least once/year, the temporary classification means that documented routine inspections and other quality assurance measures are not performed that would make the data acceptable for archival, retrieval, or future use in general scientific or interpretive studies.
