  • January 22, 2018 - USGS Water Data availability during lapse in Federal funding

    Due to a lapse in Federal funding, the U.S. Geological Survey must suspend those parts of its data collection and distribution processes requiring human intervention. However, automated reporting and serving of telemetered data will continue.

    Users may note some degradation in the quality and completeness of real-time streamflow, groundwater and water-quality data from some reporting stations due to the suspension of field calibrations and adjustments, especially as high flows occur, aquatic vegetation becomes dominant, or ice forms in high altitude streams. The USGS will continue to monitor some performance aspects of its network using a skeleton workforce.

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.

NOTICE (11/28/2017) -- Data collection at the following gage will be discontinued on December 31, 2017 due to funding reductions from partner agencies. Although historic data will remain accessible, no new data will be collected unless one or more new funding partners are found. Users who can contribute funding for the non-Federal share of costs to continue operation of this streamgage should contact Timothy Sargent at the USGS New England Water Science Center - Connecticut Office (860-291-6754) or email at tcsargen@usgs.gov.

NOTICE (11/01/2017) -- Starting on February 01, 2018 vertical gage datum at the following locations will be referenced to North American Vertical Datum of 1988 (NAVD 88), this datum reference will replace the current vertical gage datum reference National Geodetic Vertical Datum of 1929 (NGVD 29). Users with questions about these streamgages should contact Timothy Sargent, at the USGS New England Water Science Center - Connecticut Office(860-291-6754) or email at tcsargen@usgs.gov.
