71o04’08", Norfolk County, Hydrologic Unit
01090001, on right bank, 75 ft downstream from Baker Dam and 100 ft
upstream from Adams Street at Milton Village. From March 14, 2007 to December 10, 2009, at site 20 ft
upstream from Baker Dam.
DRAINAGE AREA.--101 mi2.
PERIOD OF RECORD.--November 1996 to current year.
GAGE.--Data Collection Platform with satellite telemeter. Datum of gage is 4.00 feet above National Geodetic Vertical Datum of 1929 (from station levels). From March 14, 2007 to December 10, 2009, gage was located 20 ft upstream from Baker Dam and set to National Geodetic Vertical Datum of 1929. From November 1996 to March 2007, gage was located 100 ft downstream of Baker Dam at arbitrary datum.
REMARKS.--Flow regulated by mills and reservoirs upstream. Flow affected by diversion from Charles River basin to Neponset River basin by Mother Brook (station 01104000) through Dedham and Hyde Park and by diversions to and from basin for municipal supplies.
On March 14, 2007 the stage sensor was relocated from below Baker Dam to the upstream side of Baker Dam where there is no tidal influence on the stage record. Due to the difficulties in maintaining a stage-discharge rating above Baker Dam, it was decided to relocate the stage sensor in the original gage pool below Baker Dam. The gage was relocated to the original location below Baker Dam on December 10, 2009. The datum for the current location is National Geodetic Vertical Datum of 1929. Tidal spikes will again be visible in the stage record. Falsely high discharges during tidal rises will continue to be removed prior to computation of discharge record. Stage record is affected by high tides is not adjusted.
