c-. ~ QO C\I C ~\ '<?::~ About 265 prehistoric sites are estimated to be present. These are generally much larger than sites at the other affected site areas and include 13 ball courts, features indicative of large villages. The most significant historic site of 97 significant sites in the Confluence area is Fort McDowell. The Fort McDowell Indian Community would be affected by one CAWCS alternative. Residents of this Yavapai Indian reservation would be relocated by dam construction. There are approximately 400 residents in the community, which is highly cohesive and maintains the traditional Yavapai culture, religion, and customs. The reservation a 1 so conta i ns commerci a lly-mi ned sand and gravel resources and approximately 680 acres of prime farmland. 5. New Waddell Site Area The New Waddell site area is located around Waddell Dam and lake Pleasant on the Agua Fria River approximately 45 miles northwest of Phoenix. The land in the area is mainly controlled by state, federal, and county agencies. , ~~.}~ There are no perennial streams or special use and management areas in the site area. Recreation resources and facilities include lake Pleasant and lower lake Pleasant, both used intensively by area residents, mainly for sailing, fishing and motorboating. The lakes are within lake Pleasant Regional Park. Cultural resources include an estimated 120 prehistoric sites. Eleven significant historic sites representative of agricultural, water control, and transportation activities are present. No people in the New Waddell site area would be affected by CAWCS plans. The area contains approximately 70 acres of prime farmland. 6. Downstream Area For purposes of CAWCS analysis the area affected by flooding is considered the Salt and Gila River floodplain from the Granite Reef Diversion Dam through metropol itan Phoenix to Gillespie Dam. Areas downstream of Waddell Dam on the Agua Fria River were not included in this analysis but are the subject of other flood control studies by the Corps of Engineers. Biological resources in the downstream area include Yuma clapper rail habitat, and state and federally-managed wildlife areas. There are no streams or lakes of recreational value in the downstream area. While records of prehistoric and historic sites exist for the area, these sites are generally not identifiable or are in poor condition due to previous flooding. Communities in the downstream area affected by flood control provided by CAWCS alternatives are the cities of Mesa, Tempe, and Phoenix; the Salt River Pima-Maricopa and Gila River Indian Communities 13
