PERIOD OF RECORD.--
Continuous-record gaging station, October
1937 to current year. Monthly discharge only for October 1937,
published in WSP 1302. Prior to October 1, 2011, published as Rockaway
River above Reservoir at Boonton (station 01380500).
Water-stage and air temperature recorder with telemetry
and crest-stage gage. Datum of gage is 479.00 ft above NAVD of 1988.
Prior to October 1 2011, gage was located 0.8 mi downstream, at a datum
of 364.47 ft above NGVD of 1929 (levels from New Jersey Geological
Survey benchmark), and drainage area of 116 mi2
Records fair, except for estimated discharges, which
are poor. Flow regulated by Splitrock Reservoir (see 01379990) on
Beaver Brook, 13.5 mi upstream from station. Town of Boonton diverts
water for municipal supply from Taylortown Reservoir (see 01380280),
capacity: 75,000,000 gal; and by pumping from wells in vicinity of

EXTREMES FOR PERIOD OF RECORD.--
Maximum discharge, 9,500
/s, Aug 28, 2011, on basis of step-backwater computation
of peak flow; maximum gage height, 9.31 ft, Aug 28, 2011, site and
datum then in use; minimum daily discharge, 5.7 ft3
The air 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.
