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 41° 29’53", long 71°
43’01", Washington County, Hydrologic Unit 01090005, on
right bank, 0.2 mi downstream from highway bridge at Hope Valley and
6.6 mi upstream from mouth.
DRAINAGE AREA--72.4 mi2.
PERIOD OF RECORD--Discharge: March 1941 to current year.
Water-quality records: water years 1978 to current year.
GAGE--Data Collection Platform with telephone telemeter. Datum of gage is 60.21 ft above NAVD 1988. Datum of gage previously reported as 61.11 ft above NGVD 1929. August to December 1909, nonrecording gage at site 1,000 ft upstream at different datum.
REMARKS--Some seasonal regulation by Locustville Pond on Brushy Brook since 1968. Some regulation at low flow by mills and ponds upstream until 1952; regulation greater prior to 1948.
