County, NJ, Hydrologic Unit 02040105, on left bank at Belvidere, 800 ft
downstream from Pequest River, 1,200 ft southeast of Riverton, PA, and

PERIOD OF RECORD.--
Continuous-record discharge station, October
1922 to current year.
WSP 781:1933(M). WSP 951:1940-41, Drainage
area. WSP 1432:1923, 1924(M). WDR US-2006:1904(M).
Water-stage recorder with telemetry. Datum of gage 226.43
ft above NGVD of 1929. Prior to Jan 1, 1929, non-recording gage at site
200 ft upstream at same datum.
Records good, except for estimated discharges, which
are fair. Diurnal fluctuations at medium and low flow caused by
powerplants on tributary streams. Flow regulated by Lake Wallenpaupack
and by Pepacton, Cannonsville and Neversink Reservoirs, and many
smaller reservoirs. Diversion from Pepacton, Cannonsville, and
Neversink Reservoirs. Discharges above 170,000 ft³/s from rating curve
extension on basis of flood-routing study.
EXTREMES FOR PERIOD OF RECORD.--
Maximum discharge, 273,000
ft³/s, from rating curve extented above 170,000 ft³/s on basis of

high-water mark in gage house; minimum discharge, 609 ft³/s, Sep 28,
EXTREMES OUTSIDE PERIOD OF RECORD.--

The continuous water-quality monitor is
located on the left bank of the Delaware River. Water-quality
parameters at this location are predominately influenced by the Pequest
