Division of Water Resources (DWR) Call History. The Call is a term used by the state engineer to effectively communicate the administrative status of the natural stream. The Call communicates the priority required during a specified period of time for a water right located within a specific stream or stream segment to divert under the Prior Appropriation Doctrine.
