This study presents the results of archaeological investigations undertaken within the proposed corridor of State Route 87 on the Fort McDowell Indian Reservation and Tonto National Forest, in northeastern Maricopa County, Arizona. This work was funded by the Arizona Department of Transportation (Contract 89-28) and conducted under the aegis of the Tonto National Forest. Six archaeological sites were investigated for this project, including three prehistoric lithic procurement sites, a Hohokam farmstead, a Hohokam habitation site, and a multicomponent site. Components of the latter site included both prehistoric and historic elements. The prehistoric component had occupations spanning more than 1,000 years and included materials from the late Archaic-early Pioneer period transition to the Sedentary period of the Hohokam occupation. The historic elements included a late nineteenth century farmstead, an early twentieth century schoolhouse, and a late nineteenth-early twentieth century irrigation canal. Evidence from the excavations indicate that occupation of the lower Verde River valley had commenced by the Late Archaic period. Maize production was in evidence, and semi-flexed inhumation, as well as cremation, burial was practiced. Site occupation at this time appears to have been seasonal, although reuses of site locales over a number of years was indicated. Early Pioneer occupation of the region was also seasonal, although possibly of somewhat lengthier duration than observed in the previous period. Maize agriculture is evident during this period, although wild resources continued to provide a substantial portion of the subsistence base. A stable, sedentary settlement characterizes the Colonial and Sedentary period; aspects of material culture indicate strong ties to the Salt-Gila basin area. The diversity and ubiquity of domesticated and encouraged plants points to a pervasive emphasis on cultivated products at this time, and, during the Sedentary period, there is evidence to suggest an intensification and diversification of agricultural production. Exploitation of the uplands may have been one means of expanding food production, perhaps in response to a greater demand caused by a growing population. Archaeological and archival research of the historic resources indicate that the irrigation canal, named the Velasco Ditch, was used as early as 1875. The length and configuration of this canal changed through time due to floodplain erosion; three distinct construction/maintenance episodes were documented. The termination of water delivery by c. 1906 was probably precipitated by several economic factors, as well as flood destruction. Historic habitation within the project area was by an unknown resident sometime between 1890 and 1902. The archaeological remains indicate reuse of the structure as an outbuilding or farm-related storage shed after is primary use as a residence. By 1902, the structure had burned, possibly catastrophically, and collapsed into a low mound. The sole school building was associated with the Cuba School District. The school structure was erected in 1900 and abandoned four years later, when purchased by the federal government. The failure to find artifacts surrounding the school other than those directly associated with educational activities suggests that it was not used regularly for other social or communal activities.

The Fort McDowell Indian Reservation is rich in historic and prehistoric archaeological resources. Systematic surface searches have located and recorded over 100 archaeological sites within the 40 square mile reservation. Such sites show that many groups have used the area, including the prehistoric Hohokam, the Yavapai, Anglo-Americans, and Mexican-Americans. Prior to 1984, however, only four sites at Fort McDowell had been excavated or tested. Two of the sites were prehistoric, consisting of Hohokam habitation sites, and two were historic, consisting of a beer bottle sidewalk at the old military fort and a 1900s trash scatter with a 1950s adobe-making facility. In 1984, plans by the Fort McDowell Mohave-Apache Indian Community to develop Phase I of an irrigation betterment project afforded an opportunity to undertake the most detailed study, to date, of archaeological remains on the reservation. Because federal funds would be necessary to carry out the project, federal law required that sites potentially important enough to be added to the National Register of Historic Places be identified, and that plans be made to lessen the damage to them from the proposed construction. To lessen the damage archaeological and historical information about the sites had to be collected. Knowledgeable informants who knew the history of these sites also had to be contacted. The project area contained 20 historically important sites, 11 of which could be avoided by construction. The Indian Community contracted with Archaeological Research Services, Inc. (ARS) to collect information at the nine sites which could not be avoided by the project. Please note that page 4 of this report is missing.

The Central Arizona Project (CAP) , Indian Distribution Division (IDD) is designed to deliver allocated CAP water to Indian users. The Middle Gila Basin Overview is the initial cultural resources planning study for the system. It summarizes and evaluates the extant data in an area 3,570 square miles (9,139 sq km) large, centered on the Gila River. The data suggests that archaeological sites in this area are numerous and varied, but most of all poorly-studied despite 100 years of research. A defensible culture history and chronology exists for only 35 percent of the 12,000 years of human history in the Basin. Given this, an assumption that basic interpretive frameworks are available to support sophisticated processural arguments is inaccurate. Further data analysis shows that site distributions correspond to physical and biotic zones in only the most general sense. Sites tend to be large and densely-clustered on the second terraces of major rivers; large sites, less-closely spaced are also in higher interior valleys. Sites on upper bajadas slopes appear to be specialized activity areas, while valley bottom sites contain material suggestive of encampments and villages. Most important, the patterns of previous field investigdtions more than anything else are responsible for apparent clusterings of sites. Large areas of the Middle Gila Basin remain unexplored. CAP-IDD systems are likely to encounter substantial archaeological remains along almost any intended, gravity- flow canal alignment, and in many field areas proposed for agricultural development. Of these remains, the majority can qualify, probably, for inclusion in the National Register of Historic Place because, in reality, we know so little about them.

Flooding along the Salt, Gila, Verde, and Agua Fria Rivers in February and March of 1978 resulted in extensive damage to property in Central Arizona and in the disruption of ground transportation and commerce in the greater Phoenix area. Major flooding also occurred along these rivers in December, 1978 and February, 1980. The recognition of this flooding problem, and of requirements for the regulatory storage of Central Arizona Project (CAP) water, prompted the U.S. Department of the Interior, Bureau of Reclamation (Reclamation) to initiate the Central Arizona Water Control Study (CAWCS) in July of 1978. The objectives of the CAWCS were to identify and evaluate alternative measures for flood control and regulatory water storage in Central Arizona. Both structural (i.e., dam construction or modification, levee construction), and nonstructural (i.e., flood proofing, flood plain regulation, water exchange) alternatives were to be considered within a large study area. A Safety of Dams (SOD) issue was subsequently recognized and incorporated in the CAWCS study process. As the study progressed through a consideration of eight alternative plans, a preferred alternative (the agency-proposed action) to address these objectives was selected by Reclamation. Several critical factors were considered in comparing alternative plans, and in defining the preferred plan alternative, including: - flood control performance of a plan - regulatory water storage performance - dam safety - economics (cost/benefits) - environmental impacts - social impacts - institutional constraints Each of these factors was thoroughly evaluated in relation to the plan alternatives during the three stage study process. Stage I established the parameters of the flood control and regulatory water storage problems to be addressed, defined a number of actions (termed elements) which might contribute to the resolution of these problems, and recommended specific actions that warranted further study on the basis of their performance characteristics. Of the 34 elements reviewed during Stage I, 20 were recommended for further consideration at a Stage II level of analysis. During the Stage II analysis, competing elements (those which served similar functions but which were at different locations) were compared in order to define and retain those which best served a particular function. These 10 remaining elements were then combined into 13 intermediate plans, termed systems, each of which could provide for flood control and regulatory water storage. At the beginning of Stage III, 10 elements remained in the study. These were combined into seven candidate plans, each of which satisfied flood control, safety of dams, and regulatory water storage objectives. An eighth plan (No Action) was also defined as a basis for evaluating the effects of a proposed undertaking. As the critical factors were considered in relation to each plan, two of the eight plans (numbers 4 and 5) were eliminated due to cost and associated adverse social and environmental effects. The remaining six plans were analyzed in detail; one plan (dubbed Plan 6) was subsequently identified as the agency-proposed action. In undertaking this study, Reclamation contracted with the firm of Dames and Moore to assist in defining and evaluating the alternative plans, and to prepare a draft environmental impact statement for the agency-proposed action. Archaeological Research Services, Inc., and the Arizona State University, Department of Anthropology (Office of Cultural Resource Management) were under subcontract to Dames and Moore for the historic and prehistoric cultural resource aspects of the CAWCS respectively. The historic cultural resource study was initiated in April, 1979, and concluded in December, 1981, and involved preparing reports and supporting documentation relative to each of the study stages above. For the purposes of this study, historic cultural resources are defined as those sites or properties which were occupied after the time at which written records became available for an area. As applied to the Southwestern United States, historic sites may include those in existence at or subsequent to the period of initial Spanish contact (during the 16th century).
