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.

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

Division of Water Resources (DWR) Surface Water Stations. This is a list of all stream, diversion, and reservoir gages within the state of Colorado along with their period of record.

Substitute water supply plans provide water users a mechanism to operate a plan for augmentation or change of water right with temporary approval from the State Engineer as allowed by § 37-92-308, C.R.S., or § 37-90-137(11), C.R.S.

Livestock water tanks are covered under the "Livestock Water Tank Act of Colorado" sections 35-49-101 to 35-49-116, C.R.S. These structures include all reservoirs built after April 17, 1941, on watercourses which the state engineer has determined to be "normally dry" and having a capacity of not more than ten acre-feet and a vertical height not exceeding fifteen feet from the bottom of the channel to the bottom of the spillway. Again, as with erosion control dams, the height is measured from the lowest point of the upstream toe to the crest of the spillway. No livestock water tanks can be used for irrigation purposes.
Erosion control dams are governed under Colorado statute (see section 37-87-122, C.R.S. (1990). These types of structures may be constructed on water courses which have been determined by the state engineer to be normally dry (which for our purposes is dry more than 80% of the time). Structures of this type cannot exceed fifteen feet from the bottom of the channel to the bottom of the spillway and cannot exceed ten acre-feet at the emergency spillway level. The height of the dam is measured vertically from the lowest point of the upstream toe to the crest of the dam in contrast to those measured vertically from the centerline pursuant to section 37-87-105, C.R.S. (1990). Note: The structure can be larger than specified under section 37-87-122, however, it then will be evaluated and must be constructed pursuant to section 37-87-105.

Hydrology Basin Phases initiated post-flood event of September 2013. The State of Colorado created a first-of-its-kind watershed restoration program utilizing funding from U.S. Department of Housing and Urban Development (HUD). Through Community Development Block Grant – Disaster Recovery funds, the Watershed Resilience Pilot Program provides grants to watershed coalitions for staff support and resilient river restoration projects. These grant funds build coalition capacity, bringing together the diverse range of stakeholders required to restore disaster-impacted watersheds. River restoration projects in this program not only restore natural systems, but achieve multiple benefits, such as increasing community connectivity by tying into trail systems, promoting safety by protecting infrastructure, enhancing local economy by incorporating recreational opportunities and building resiliency for communities and ecosystems. These are the basins and associated phases
