DWR Calls History

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. The basic purpose of the Call is to “call out” water rights that are not in priority in order to make water available to the senior water right that is diverting less than its decreed amount of water that it could beneficially use.

水资源部（DWR）调用记录数据集。此处所称的“调用（Call）”是州工程师用于精准传达天然河道行政状态的专用术语。该调用会明确指定时段内，位于特定河道或河道段内的水权，依据优先占用原则（Prior Appropriation Doctrine）进行引水时所需遵循的优先级规则。该调用机制的核心目的在于“点名”优先级较低的水权，以将水资源腾让给实际引水量低于其核定可有益使用水量的优先水权方。
