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.

PROVISIONAL DATA SUBJECT TO REVISION

Click to hidestation-specific text
Station operated in cooperation with the Connecticut Department of Energy & Environmental Protection.
Boating safety tips
The 15-minute Precipitation data for this station are temporary and will only be displayed for 120 days. Time series of 15-minute daily values will NOT be available for retrieval following the 120-day display period. The temporary classification means that documented routine inspections and other quality assurance measures are not performed to the level required to make the data acceptable for archival, retrieval, or future use in general scientific or interpretive studies.
This station managed by the East Hartford CT Field Office.
