GIS (Geographic Information System) is a computerized mapping system.

Leaching is the process where soluble substances, such as minerals, salts, or pollutants, are dissolved and washed out of a porous solid like soil or rock by a percolating liquid, typically water. This can result in the loss of soil nutrients, contamination of groundwater, or the separation of desired compounds from a solid mixture. 

Integrated Decision Support Consumptive Use (IDSCU) is an efficient model for computing field & farm consumptive use.

Class B, C, and D Water Allotment Contracts are legal documents used to provide augmentation to member wells.

In water contracts, a "Change of Use" refers to modifying how an existing water right is used. The new use for the water may differ from what was initially permitted or decreed. 

Annual assessments are fees paid by well users to Central to allow them to pump wells out-of-priority.

The water year is April 1 to March 31 of any given year.

Augmentation Plans are a broad category of water operations designed to increase the supply of water available for beneficial use. Commonly, an augmentation plan authorizes out-of-priority diversions for beneficial use to the extent that a replacement supply of water is made available to substitute for the otherwise diminished amount of water available to supply other water rights. This allows the junior diversion to operate without injury to senior vested water rights. Augmentation plans enable flexibility and maximize water utilization while protecting senior rights in over-appropriated stream systems throughout Colorado.
