The Arizona Legislature established ADEQ as the state’s environmental regulatory agency under the Environmental Quality Act of 1986. Its mission is to protect and enhance public health and the environment in Arizona. The department achieves this mission by administering our state’s environmental laws and delegated federal programs to prevent pollution of our air, water and land, and to clean up such pollution when it occurs. The department’s organizational structure is composed of four programmatic divisions that fulfill our environmental protection mission in the areas of air quality, water quality, waste programs, and tank programs.

The Upper Hassayampa groundwater basin covers approximately 787 square miles within Maricopa and Yavapai counties and is located about 60 miles northwest of Phoenix. The basin is characterized by mid-elevation mountains and had an estimated population of 10,479 in 2000. The largest population center is the Town of Wickenburg. Other communities include Congress and Groom Creek. Low-intensity livestock grazing is the predominant land use and most ranches have limited acreages of irrigated pasture to raise additional animal feed. There are no surface water diversions or impoundments besides small stock ponds within the basin. Groundwater is the only source for public water supply, domestic, irrigation and industrial purposes. Public water supply uses the most groundwater in the basin.

The Aravaipa Canyon groundwater basin covers approximately 517 square miles in southeastern Arizona within Graham and Pinal counties. Largely undeveloped, the remote basin has an estimated 135 residents and includes the community of Klondyke. Low-intensity livestock grazing is the predominant land use although there are some irrigated fields and orchards along Aravaipa Creek. Historic mining activity resulted in the creation of the Klondyke Tailings Water Quality Assurance Revolving Fund site in 1998. Groundwater is used for all domestic purposes within the basin as well as most irrigation and stock water supplies. Irrigation uses the most groundwater in the basin.

For two and a half decades, the men and women of ADEQ have dedicated themselves to the noble cause of environmental stewardship. They have helped us respect the delicate balance between the natural world and the people who depend on it for sustenance, prosperity and a rewarding quality of life. Most importantly, they have served diligently and passionately to conserve and protect Arizona's natural bounty for generations to come.

The purpose of this plan is to provide information and recommendations to guide Arizona State Parks and other agencies in Arizona in their management of motorized and nonmotorized trail resources, and specifically to guide the distribution and expenditure of the Arizona Off-Highway Vehicle Recreation Fund, trails component of the Arizona Heritage Fund and the Federal Recreational Trails Program. This plan includes both motorized and nonmotorized trail information, public involvement results and recommendations for future actions regarding trails in Arizona.

This planning document details the results of extensive surveys of Arizonans’ thoughts, preferences and priorities regarding trails and off-highway vehicle routes. Throughout the year 2008, staff at Arizona State Parks and faculty at Arizona State University partnered to solicit information from more than 5,500 Arizonans about what types of motorized or non-motorized trails they use, how often they use trails, what they like or don’t like about trails, and what trail managers should focus their time and dollars on to make the trail experience better.
