USGS Water Data for Connecticut

Click to hide state-specific text

Starting on January 27, the Connecticut Office of the USGS has transitioned to a new data management software package. While you may not have noticed this transition, some sites may have problems or delays in being updated. We are actively monitoring these conditions and are resolving them as quickly as possible. Thank you for your patience, and please contact Mike Colombo (mjcolomb@usgs.gov 860-291-6751) for more information.


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.

Introduction

The U.S. Geological Survey's (USGS) National Water Information System (NWIS) is a comprehensive and distributed application that supports the acquisition, processing, and long-term storage of water data. USGS Water Data for the Nation Site serves as the publicly available portal to a geographically seamless set of much of the water data maintained within NWIS (additional background).

USGS Water Data for the Nation Site provides access to water data from over 1.5 million sites in all 50 States and additional border and territorial sites. The data are organized within the categories listed to the left.

The water data available via this site have been acquired as part of the USGS investigations of the occurrence, quantity, quality, distribution, and movement of the surface and underground waters that constitute the Nation's water resources. Additional information about the USGS and water resources of the Nation is available at water.usgs.gov.
