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 42°18’54", long 71°23’01", Middlesex County, Hydrologic Unit 01070005, on right bank, 10 ft upstream from Lake Cochituate Dam at Framingham.
DRAINAGE AREA--21.1 mi2.
PERIOD OF RECORD-- August 2010 to current year.
GAGE--Data Collection Platform with telephone telemeter. Datum of gage is 129 ft above NAVD 1988, estimated from topographic map.
COOPERATION--Town of Framingham.
REMARKS--Lake elevation may be affected by heavy winds. Lake elevation controlled by weir with flash boards and a small bypass channel with flash boards. Minimum elevation of flash boards is 8.02 ft (weir) below which a small amount of outflow from the lake occurs from leakage around and through the control.

This station managed by the Northborough MA Field Office.
