NOTICE: Starting on January 27, the New Hampshire and Vermont Offices of the New England Water Science Center have transitioned to a new data management software package as part of a national effort. While you may not notice this transition, some sites may have problems or delays being updated. We are actively monitoring these conditions and are resolving them as quickly as possible. Thank you for your patience. Please contact Rick Kiah at rkiah@usgs.gov for more information or if concerns.

The colored dots on this map depict streamflow conditions as a percentile, which is computed from the period of record for the current day of the year. Only stations with at least 30 years of record are used.
The gray circles indicate other stations that were not ranked in percentiles either because they have fewer than 30 years of record or because they report parameters other than streamflow. Some stations, for example, measure stage only.

Statewide Streamflow Real-Time Table

Real-time data typically are recorded at 15- to 60-minute intervals, stored onsite, and then transmitted to USGS offices every 1 to 4 hours, depending on the data relay technique used. Recording and transmission times may be more frequent during critical events. Data from real-time sites are relayed to USGS offices via satellite, telephone, and/or radio telemetry and are available for viewing within minutes of arrival.

All real-time data are provisional and subject to revision.
