Whether reintroduction and recovery should be allowed, and if so where and how, were hotly debated through the 1990s, when reintroduction was formally proposed. They still are. Regardless, the proposal process ended with a nonessential experimental population rule (hereafter Final Rule) approved on January 12, 1998. In keeping with the stated experimental nature of the reintroduction effort, and respectful of the doubts expressed by many, the Final Rule required full evaluations after 3 and 5 years to recommend continuation, modification, or termination of the Reintroduction Project. The 3-Year Review, conducted in 2001, concluded that reintroduction should continue, albeit with important modifications. However, as we discuss elsewhere in this report, for many reasons the 3-Year Review recommendations were not implemented, at least not to the extent that interested parties and stakeholders expected or desired. Regardless of cause, the apparent lack of closure was a significant agency and public concern when the time came for the next review.

By agreement among the primary cooperating agencies, responsibility for the Reintroduction Project’s 5-Year Review fell to the Mexican Wolf Blue Range Adaptive Management Oversight Committee (AMOC) that oversees the Project on behalf of six Lead Agencies and various formal and informal Cooperator agencies. AMOC and the Project's Interagency Field Team conducted the 5-Year Review to comply with the Final Rule, but above and beyond that the intent was to identify and implement improvements in the Project. The Review consists of several primary components: Administrative, Technical, Socioeconomic, and Recommendations. Each is detailed in this report. Review and adaptive management of the Reintroduction Project will not stop with this review. Project cooperators will continue to seek internal and public input regarding Mexican wolf reintroduction to help achieve recovery goals and objectives.

Originally, the purpose of the study was to obtain either a Letter of Map Revision or a Physical Map Revision from the Federal Emergency Management Agency. Unfortunately, during the initial stages of the investigation, it became apparent that FEMA's guidelines for these types of map revisions could not be accommodated, primarily due to flow-distribution conflicts.

The purpose of the study is to identify existing flooding problems for fifteen homes adjacent and west of Holladay Street which have experienced flooding in the past three years. A 1991 follow-up report is included that corrects an error in the earlier report's estimation of the split flow quantities at the intersection.

Covers an area in southeastern Pima County that drains the Arivaca Creek watershed. The purpose of the report is to estimate peak discharge for the 50 year storm frequency event, utilizing the rational method (Q=CiA). This method pre-dates that outlined in the Hydrology Manual for Engineering Design and Floodplain Management within Pima County, Sept. 1979, and is considered less accurate. It is recommended that this report be archived and discontinued for use for regulatory purposes.

The Arizona Department of Transportation, the Arizona Game & Fish Department and the Arizona State Parks Board are required to conduct a study every three years on watercraft fuel consumption and recreational watercraft usage. The fuel consumption data is collected to determine the allocation of motor vehicle fuel tax to the State Lake Improvement Fund. The information on recreational watercraft usage patterns on Arizona’s lakes and rivers is necessary, in part, to determine the distribution of SLIF funds to applicants.

The U.S. Fish and Wildlife Service (Service) is the lead agency responsible for recovery of the Mexican wolf, pursuant to the Endangered Species Act. The Mexican Wolf Recovery Program essentially is separated into two, interrelated components: 1) Recovery – includes aspects of the program administered primarily by the Service that pertain to the overall goal of Mexican wolf recovery and delisting from the list of threatened and endangered species, and 2) Reintroduction – includes aspects of the program implemented by the Service and cooperating States, Tribes, and other Federal agencies that pertain to management of the reintroduced Mexican wolf population in the Blue Range Wolf Recovery Area, which consists of the entire Apache and Gila National Forests in Arizona and New Mexico. This report details all aspects of the Mexican Wolf Recovery Program.
