UPDATE, 11/9: As of November 8, the USGS has successfully restored all of the operational gages that stopped transmitting due to an issue with the satellite telemetry system that records and transmits data.  The USGS will now focus on restoring other equipment that experienced the telemetry issues, including about 85 rapid deployment gages that are used periodically for emergency response.

UPDATE, 11/6: Once all operational gages are brought back online, the USGS will focus on restoring other equipment that experienced the telemetry issues, including about 85 rapid deployment gages that are used periodically for emergency response.  

UPDATE, 11/5: The USGS continues to make progress on restoring all of its gages. As of 3 p.m. Monday, November 5, less than 1 percent of USGS streamgages are still not transmitting due to an issue with the satellite telemetry system that records and transmits  data. The list of affected gages has been updated.

UPDATE, 11/2: The USGS continues to make progress on restoring all of its gages. As of 3 p.m. Friday, November 2, less than 3 percent of USGS streamgages are still not transmitting due to an issue with the telemetry system that records and transmits streamgage data. The USGS will continue to work through the weekend to bring the streamgages back online. The list of affected streamgages has been updated.

UPDATE, 11/1: The USGS continues to make progress on restoring all of the gages. As of noon Thursday, November 1, approximately 4.5 percent of USGS streamgages are still not transmitting due to an issue with the telemetry system that records and transmits streamgage data. The list of affected streamgages has also been updated.  

UPDATE, 10/31: The USGS continues to make progress on restoring all of the gages. As of noon Wednesday, October 31, approximately 6 percent of USGS streamgages are still not transmitting due to an issue with the telemetry system that records and transmits streamgage data. The list of affected streamgages has also been updated.  

UPDATE, 10/30: As of noon Tuesday, October 30, approximately 7.5 percent of USGS streamgages are still not transmitting due to an issue with the telemetry system that records and transmits streamgage data. The USGS continues to work on bringing the streamgages back online as quickly as possible. The data on the streamgages is being preserved for download and has not been lost. The list of affected streamgages has also been updated.

UPDATE, 10/29: As of 10 a.m. Monday, October 29, approximately 9 percent of USGS streamgages are still not transmitting due to an issue with the telemetry system that records and transmits streamgage data. The USGS continues to work on prioritized streamgages, those in geographic areas expected to receive rainfall over the next few days, replacing the component that transmits the data as quickly as possible. The USGS is working hand-in-hand with the manufacturer to find a solution to the transmitter issue. 

The data on the streamgages is being preserved for download and has not been lost.

UPDATE, 10/26: The USGS is working overtime to bring gages back online. As of 10:00 a.m. Friday, October 26, 10 percent of USGS streamgages are still not transmitting due to an issue with the telemetry system that records and transmits streamgage data. With the National Weather Service and numerous other federal, state, and local partners, the USGS is determining priorities for restoration.  On-stock nationwide inventory is quickly being distributed based on that prioritization and work will continue through the weekend.

UPDATE, 10/25: The list of affected streamgages has been updated. At this time, the number of streamgages affected has fallen to about 950, or 11 percent of the network.

The USGS is working to restore the approximately 14 percent of streamgages that are offline due to an issue with the telemetry system that records and transmits streamgage data. The USGS has identified and made its highest priority getting back online first those gages in geographic areas expected to receive significant rainfall over the next few days.

Cooperators and partners are being informed about affected streamgages at the local level.

The outage started on Saturday, October 20. Gages in 43 states are affected.

It’s unclear how long this issue will continue but data collected during this time should be available when the affected gages are back online.

A list of the affected streamgages is available here.

Streamgage status can be searched by river or stream, or by specific streamgage number at https://maps.waterdata.usgs.gov/mapper/index.html. Please type the gage number or name into the search options on the left-hand side of the mapper.

For questions about a streamgage in your state, please contact your local USGS water science center; contacts can be found at https://water.usgs.gov/key_officials.html.

There are approximately 8,300 USGS-operated streamgages across the country that measure water levels, streamflow, and rainfall. Information provided through the USGS National Streamflow Network forms the scientific basis for decision-making related to protection of life and property from water-related hazards, such as floods; cost-effective management of freshwater that is safe and available for drinking, irrigation, energy, industry, recreation, and ecosystem health; and national, state, tribal, and local economic well being. The USGS provides this data to federal, state, and local agencies, as well as to the public.

For more than 125 years, the USGS has monitored flow in selected streams and rivers across the United States.

The USGS will provide updates as they are available.
