LOCATION.--Lat 42° 34’10", long 71°
01’39", Essex County, Hydrologic Unit 01090001, on right bank in
Peabody, 700 ft downstream from Boston Street Bridge at South Middleton, 1.3
mi downstream from Wills Brook, and 2 mi south of Middleton.
DRAINAGE AREA.--44.5 mi2.
PERIOD OF RECORD.--Discharge: June 1938 to current year.
Water-quality records: Water years 1957, 1959, 1999.
REVISED RECORDS.--WSP 1301: 1942(M). WSP 1621: 1938–58 (monthly
runoff). WDR MA-RI-84-1: Drainage area.
GAGE.--Water-stage recorder and concrete control. Datum of gage is 44.97
ft above sea level (Massachusetts Geodetic Survey benchmark.)
REMARKS.--Records fair except those for estimated daily discharges and
those for discharges less than 10 ft3/s, which are poor.
Diversions upstream for municipal supply of Reading, Lynn, and Peabody.
Occasional regulation by mill upstream. Satellite gage-height telemeter at
station.
NOTICE.--Corrections to the discharge records computed from the stage-discharge
relation are made from periodic
discharge measurements (green X on discharge and stage graphs). The USGS actively adjusts discharge records to minimize the
backwater effects from beaver dams, however, backwater conditions can change between measurements.
As a result, discharge records at this site are considered poor.
COOPERATION BY.-- Massachusetts Department of Conservation and Recreation, Office of Water Resources and Department of Environmental Protection, Office of Watershed
Management.
