Division of Water Resources (DWR) Active Calls. 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.

All well applications and permits issued.

This dataset contains Water Quality files related to Stream Impairment in Colorado. The individual Lake or Stream may be in multiple files on top of each other. The user may need to check on and off the layers in the Contents, or cycle through multiple records when identifying a feature.

A Jurisdictional Dam is a dam creating a reservoir with a capacity of more than 100 acre-feet, or creates a reservoir with a surface area in excess of 20 acres at the high-water line, or exceeds 10 feet in height measured vertically from the elevation of the lowest point of the natural surface of the ground where that point occurs along the longitudinal centerline of the dam up to the crest of the emergency spillway of the dam. For reservoirs created by excavation, or where the invert of the outlet conduit is placed below the surface of the natural ground at its lowest point beneath the dam, the jurisdictional height shall be measured from the invert of the outlet at the longitudinal centerline of the embankment or from the bottom of the excavation at the longitudinal centerline of the dam, whichever is greatest. Jurisdictional height is defined in Rule 4.2.19. The State Engineer shall have final authority over determination of the jurisdictional height of the dam.
