PROVISIONAL DATA SUBJECT TO REVISION

Click to hidestation-specific text

LOCATION--Lat 42o22'21", long 71o16'15", Middlesex County, Hydrologic Unit 01090001, 20 ft downstream of culvert at ramp from southbound lane of State Highway 128, 800 ft upstream from mouth, 1.8 mi west of Waltham.
DRAINAGE AREA--0.48 mi2.
PERIOD OF RECORD--October 1997 to September 1998; October 2000 to current year.
GAGE--Data Collection Platform, water-temperature and specific conductance monitor with telephone telemeter. Datum of gage is 84.20 ft above NAVD 1988, estimated from topographic map. Datum of gage previously reported as 85 ft above NGVD 1929, estimated from topographic map. Dissolved chloride estimated from specific conductance measurements using the superposition technique described in Granato and Smith 1999.
COOPERATION BY--Cambridge Water Department
