  NOTICE:There is a service interruption for a number of stream gauges nationwide due to the Global Positioning System (GPS) Rollover that occurred on April 6 at 23:59 GMT. The National Weather Service is working with federal, state, and local partners to ensure those affected gauges obtain the necessary updates to resume data transmission. We apologize for the service interruption and hope to have the data restored as soon as possible.
