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

SURFACE-WATER RECORDS
LOCATION.--Lat 40°38'58", long 74°40'54"
referenced to North American Datum of 1983, Bedminster Township,
Somerset County, NJ, Hydrologic Unit 02030105, on right bank just
upstream of low dam, 1,200 ft upstream of bridge on River Road East
(Cutting Whitney Road), 2,400 ft downstream of Hoopstick Brook, 1.2 mi
northeast of Burnt Mills, and 2.2 mi west of Pluckemin.
DRAINAGE AREA.--6.67 mi².
PERIOD OF RECORD.--Low-flow partial-record station, water years
1964-67, 1975. Continuous-record discharge station, June 2006 to
current year.
GAGE.--Water-stage recorders with telemetry and crest-stage
gages upstream and downstream of concrete dam with stainless-steel
v-notch in the center. Datum of gage is 83.26 ft above NAVD of
1988.
REMARKS.--Records fair, except for estimated discharges, which
are poor. Flow past station may be affected by irrigation pumpage
upstream of gage. Stage-discharge relationship can be affected by
variable-stage backwater from North Branch Raritan River. A downstream
auxiliary gage at station is used when variable stage backwater
conditions exist.
EXTREMES FOR PERIOD OF RECORD.--Maximum discharge, 2,570 ft³/s,
Aug 28, 2011, gage height, 10.79 ft; maximum gage height, 12.45 ft, Aug
28, 2011, affected by backwater from North Branch Raritan River;
minimum discharge, 0.00 ft³/s, many days.
