ICE EFFECTS ON STREAMFLOW

The formation of ice on rivers can cause discharge values to appear unusually high. Display of these erroneous discharge data may result in improper assessment of flow conditions and misuse of the data. For this reason, display of discharge values for streams significantly affected by ice may be disabled from view. Display of discharge data will resume when ice conditions are no longer present. Discharge values for streams minimally affected by ice will continue to be displayed. Flows for streams with these conditions appear to increase during the night and decrease to near-base-line conditions around midday. To estimate the correct discharge for these streams, use the flow rate that corresponds to the bottom of the discharge curve, rather than the peak that corresponds to the top of the curve. Note that this method of estimation is possible only when no surface runoff is occurring. Daily mean discharges for periods of both significant and minimal ice-effect will be estimated and published in the Annual Water-Data Report for the water year in which they occurred.

LOCATION--Lat 42o22'22", long 71o49'43", Worcester County, Hydrologic Unit 01070004, on left bank 300 ft upstream from bridge on Harris Street at Canada Mills, 2.1 mi north of Holden, and about 3.5 mi upstream from mouth at Wachusett Reservoir.
DRAINAGE AREA--46.3 mi2.

WATER-DISCHARGE RECORDS

PERIOD OF RECORD--November 1996 to current year.
GAGE--Data Collection Platform with satellite telemeter. Datum of gage is 545 ft above NAVD 1988, estimated from topographic map. Prior to May 13, 2020, datum of gage reported as 560 ft above NGVD 1929, estimated from topographic map.
REMARKS--Flow occasionally regulated by Quinapoxet Reservoir.

WATER-QUALITY RECORDS

PERIOD OF RECORD--April 1997 to current year.
INSTRUMENTATION--Water temperature and specific conductance monitor and heated tipping-bucket precipitaion gage.
Daily and unit values for precipitation data are calibrated and quality assured prior to publication by the USGS MA-RI Field Office. Data are available upon request.

This gage is monitored in cooperation with the Massachusetts Department of Conservation and Recreation, Division of Water Supply Protection, Office of Watershed Management, with funding from the Massachusetts Water Resources Authority .
