The primary purpose of the Inventory is to identify storage capacity available to the Arizona Water Banking Authority to meet its water storage goals. Inclusion of a facility in the Inventory does not equate to a commitment by the AWBA to utilize any specific facility in the future. The AWBA will continue to determine annually which facilities will be used through the development of the Annual Plan of Operation. Conversely, not including a facility in the Inventory does not preclude the AWBA from utilizing that facility in a future Annual Plan. It does, however, preclude the facility from being utilized for interstate water storage, until such time as it is included in an updated Inventory.

The purpose of the Inventory is to determine whether storage facilities exist in this state to meet the water storage needs of the authority for the following ten years. The Authority approved the initial Inventory in 1997. Because additional storage facilities are continually being constructed, the Authority updates the Inventory at least once every five years. The Authority has been annually updating all new facilities that could be utilized by the Authority in its Annual Report. It is important to note that the primary purpose of the Inventory is to identify the capacity that is available for potential storage by the Authority to meet its objectives. The inclusion of a facility in the Inventory does not equate to a commitment by the Authority that the facility will be utilized for water banking purposes in the future. The Authority will continue to determine annually which facilities will be used through the development of an Annual Plan of Operation. Conversely, a facility that is not included in the Inventory may be utilized in a future Annual Plan of Operation.
