District 47 Illinois River call record

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.

水资源管理局（DWR）通话历史数据集。通话一词系由国家工程师用于有效传达自然溪流的行政管理状态。通话传达了在指定时间段内，位于特定溪流或溪流段落内的水权，根据先占水权原则进行改道所需的优先级。通话的基本目的是为了‘唤起’非优先级的水权，以便为那些改道水量少于其被许可的有益使用量的优先级较高的水权提供水源。
