StreamStats version 3, which was no longer being supported, was shut down on January 30, 2018.  Web services, the batch processor, and individual state web pages that linked to StreamStats version 3 are no longer functioning.  Users are asked to use StreamStats version 4 application (https://streamstats.usgs.gov/ss/) and the new web pages (https://water.usgs.gov/osw/streamstats/). The StreamStats Development team is has developed a new batch processor and most of the web services for StreamStats version 4. The remaining web services will be completed in the near future.
