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.

A Water Right is a property right that is either conditional or
absolute and conveys the right to use a particular amount of
water, with a specified priority date as confirmed by the
water court. The Net Amounts List contains the current status of a water right based on all of its court decreed actions.

Contains physical, manmade structures used for diverting, storing, releasing, or measuring water; structures are associated with specific bodies of water.

Current streamflow conditions

The Surface Water Supply Index (SWSI) is used as an indicator of surface water supply conditions in Colorado. The SWSI compares the total volume of water in a basin or sub-basin against the volume available in the same month of historical years. Depending on the month, the volume is a combination of components: streamflow, streamflow forecast, or reservoir storage. The SWSI is calculated for Colorado’s river basins and sub-basins; this data set provides information on the Colorado’s sub-basin-level SWSI calculation.
