An Archaeological Resurvey and Assessment of 15 Previously Recorded Sites on the Bureau of Reclamation Right-of-Way Along the Hayden-Rhodes Aqueduct, Central Arizona Project Canal, Located in La Paz County, Arizona

The Bureau of Reclamation has developed an archaeological site database for the Central Arizona Project (CAP) canal main stem based on Class III survey data that includes all previously recorded sites. An unknown number of these sites were either destroyed by construction or excavation, while others are no longer located within the CAP right-of-way (ROW). To assist Reclamation in checking the accuracy of its site database, Northland Research, Inc. (Northland) was asked to relocate and record 19 sites that had been identified along the Hayden-Rhodes Aqueduct (formerly the Granite Reef Aqueduct) of the CAP system.

Northland surveyed 998 acres and reassessed 15 of the 19 previously recorded sites within the CAP right-of-way. Four sites were not relocated. Only two sites (AZ S:1:27[ASM] and AZ S:1:28[ASM]) were recommended eligible for inclusion in the National Register of Historic Places. The remaining 13 sites were recommended not eligible or non-contributing for those components within the CAP right-of-way.
