ALERT: December 5th update on the status of the nationwide data transmission error preventing stream gauge data collected at affected locations from being displayed on the Advanced Hydrologic Prediction Services (AHPS) webpages. As of 11/08/2018, The USGS has restored all impacted operational stream gauges to transmitting status. The status map of gauge outages from other agencies is here. The outage map will be updated each Thursday. We apologize for the service interruption and hope to have the data restored as soon as possible.
