USGS Water Data for Massachusetts

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.

You would need to substitute the applicable items enclosed in brackets (remove the brackets too) for the date you accessed the data and URL you are referring to within Water Data for the Nation.

While the development team will take considerable effort to maintain the integrity of existing URLs, queries for specific data within Water Data for the Nation may not function in the future if the software or database is substantially changed.
