The Massachusetts-Rhode Island office of the
New England Water Science Center has transitioned to a new data
management software package. While you may not notice this transition,
some sites may have problems or delays in being updated. We are
actively monitoring these conditions and resolving them as quickly as
possible. For more information contact Richard Verdi at rverdi@usgs.gov
or 508-490-5064. See the December 8th news entry at: https:/

ICE EFFECTS ON STREAMFLOW During winter, ice formation may cause stage and discharge values to appear higher than expected. Ice effects may be minor (occurring only at night and early morning) with baseline flows obvious, or the effects may be major (stage constantly increases over several days or weeks) resulting in greatly erroneous discharge. Streamgages experiencing minor ice conditions will continue to display stage and discharge values to enable users to estimate the approximate base-line stage and discharge. Streamgages experiencing major ice conditions will have the discharge record temporarily disabled to prevent use of erroneous discharge values. The discharge record will resume when it is determined that ice conditions are no longer present. Daily mean discharges during periods of ice effect will be estimated after detailed data analysis.
