The Hydrology Division of the Arizona Department of Water Resources has been in the process over the last two years of updating the geology used in the Department’s Salt River Valley Regional Groundwater Flow Model. The geology update is the first phase of an overall plan to update the model’s geologic structure, numerical grid and extend the model’s steady-state and transient calibration periods. Releasing the provisional geologic report at this time allows us to provide the new data and analysis to water providers and other model users prior to the completion of the overall model update. Please be advised that the geologic data and interpretations that are included in this report and accompanying database are provisional at this time and subject to revision.
As a result of high growth rates, physically and legally limited water supplies, drought, economic constraints, and relatively little comprehensive water resource planning and management, water supplies are stressed in some parts of Arizona. The Arizona Department of Water Resources has collected and synthesized currently available water-related information for the State of Arizona into a “water atlas,” organized by planning area.
Provides a comprehensive overview of regional water supply and demand conditions that has not been available on a statewide basis for over ten years.
Realizing the need for drought preparedness in Arizona, a Governor’s Drought Task Force was created in 2003 and the Arizona Drought Preparedness Plan developed. The plan was adopted in 2004 and its continued implementation ordered in 2007. It established a framework to monitor drought, improve understanding of drought impacts, and determine mechanisms for limiting future vulnerability. The Arizona Department of Water Resources coordinates these activities and prepares the Arizona Drought Preparedness Annual Report each year.
The Arizona Department of Water Resources manages the state’s water supply. Water management includes a wide variety of activities that are intended to protect and preserve the water supply. Examples of these activities include licensing well drillers, assuring the safety of dams, and developing mandatory conservation requirements for all water use sectors in Active Management Areas, protecting the state’s Colorado River allocation and facilitating Indian water rights negotiations among tribal representatives, local interests, federal and state officials and members of Congress.
The Arizona Water Banking Authority was created in 1996 to store the unused portion of Arizona’s annual allocation of the Colorado River. By storing this unused water the AWBA secures a dependable water supply necessary to ensure the state’s long-term prosperity. The plan is intended to govern the operations of the AWBA over the course of the entire calendar year.
The Arizona Water Banking Authority was created in 1996 to store the unused portion of Arizona’s annual allocation of Colorado River water. Until the AWBA was created, Arizona had not fully utilized its 2.8 million acre-foot allocation of Colorado River water and the state’s leaders recognized that leaving a portion of Arizona’s allocation in the river was a lost opportunity. The AWBA was created to provide assurances that water users within the state had secure, long-term water supplies.
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.
Water banking is one of Arizona's most important water management strategies, and its success depends on effective planning. This joint plan helps advance the objective, articulated in the intergovernmental agreement among CAP, ADWR and AWBA, to develop a coordinated and cooperative planning process that includes distribution and recovery of water stored by the AWBA.
Each year, information is requested from cities, towns, private water companies, and water improvement districts in an effort to summarize and document water conservation activities implemented within Active Management Areas.
