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.

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.

This document embraces two components. First, a Conservation Assessment describes the current status of the jaguar in the United States, and identifies and assesses risks to the jaguar in Arizona and New Mexico. The Assessment focuses the second component, the Conservation Strategy, on reducing or eliminating these threats in Arizona and New Mexico, which might allow for expansion of the range currently occupied by the Arizona subspecies, and thus contribute to promoting recovery of the species.
Information in this document comes primarily from the state level, an approach that considers regional variation and provides a complete habitat and species assessment.

In March 1997, the Arizona Game and Fish Department and New Mexico Department of Game and Fish entered into a Conservation Agreement with other state, local, and federal cooperators, with voluntary participation by many private individuals, to conserve the jaguar (Panthera onca) along borderlands of Arizona and New Mexico and to stimulate parallel efforts in Mexico. The agencies believed that if strong partnerships could be developed under this approach, it would be a significant step forward in bringing local governments, private landowners, and nongovernmental organizations directly into jaguar management.

The southwestern United States and Sonora, Mexico are the extreme northern limits of the jaguar’s (Panthera onca) range, which primarily extends from central Mexico south through Central and South America to northern Argentina. Recently, the jaguar ranged as far north as Arizona, New Mexico, and Texas. Over the last century, the jaguar’s range has been reduced to approximately 46% of its historic range due to hunting pressure and habitat loss. The greatest loss of occupied range has occurred in the southern United States, northern Mexico, northern Brazil, and southern Argentina. Since 1900, jaguars have been documented occasionally in the southwestern United States, but the number of sightings per decade has declined over the last 100 years with only 4 verified sightings between 1970 and 2000. The objectives of our analysis were twofold: (1) characterize potential jaguar habitat in Arizona from historic sighting records, and (2) create a statewide habitat suitability map.
