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.

The statistics generated from this site are based on approved daily-mean data and may not match those published by the USGS in official publications. The user is responsible for assessment and use of statistics from this site. For more details on why the statistics may not match, click here.
