  • There is currently an issue affecting the delivery of a subset of satellite data transmissions. The issue is impacting the delivery of recent time-series water data from numerous gaging stations, particularly those in the western United States, to USGS Water Data for the Nation and Water Services. The USGS Water Mission Area is working with partner agencies to recover these systems as soon as possible.
    • Update: Recovery of the impacted satellite data delivery system is ongoing at this time. While a majority of recent data from sites in the western U.S. are now being received, there are still sites which remain behind pending full resolution of the issue.
