RIVER BASIN SURVEYS 



The Kiver Basin Surveys, organized in 1946 as a unit of the Bureau 

 of American Ethnology to carry into effect a memorandum of under- 

 standing between the Smithsonian Institution and the National 

 Park Service providing for the salvage of archeological and paleon- 

 tological materials that will be lost as a result of the nation-wide 

 program for flood control, irrigation, hydroelectric, and navigation 

 projects sponsored by the Federal Government, continued its opera- 

 tions during the year. As in the past, the investigations were con- 

 ducted in cooperation with the National Park Service and the Bureau 

 of Reclamation of the Department of the Interior, the Corps of 

 Engineers, Department of the Army, and a number of nongovern- 

 mental local institutions. The work was financed by the transfer of 

 $145,400 ($20,000 of which was appropriated in the 2d Deficiency 

 Act and did not become available for actual use until the beginning 

 of fiscal 1950) to the Smithsonian Institution by the National Park 

 Service. The money comprising these funds was derived in part 

 from the Bureau of Reclamation and in part from the National Park 

 Service. 



- Activities in the field consisted mainly of reconnaissance or surveys 

 for the purpose of locating sites that will be involved in construction 

 work or are so situated that eventually they will be inundated. There 

 was a limited testing of sites to determine their nature and extent, 

 where such was deemed essential, and at seven locations extended 

 excavation or intensive testing was carried on. The surveys covered 

 67 reservoir areas scattered throughout 8 river basins and 14 States. 

 At the end of the year the total of the reservoir areas surveyed or 

 where some digging has been done since the start of the program in 

 July 1946 had reached 154 located in 21 States. During the course 

 of the work 2,107 archeological sites have been recorded, and of that 

 number 456 have been recommended for excavation or further testing. 

 Thus far prehminary appraisal reports have been finished for all the 

 reservoirs, and 97 have been mimeographed for distribution to the 

 cooperating agencies. Where several reservoirs form a unit in a single
