RIVER BASIN SURVEYS 
The River Basin Surveys, a unit of the Bureau of American 
Ethnology organized to carry into effect a memorandum of under- 
standing between the Smithsonian Institution and the National Park 
Service providing for the recovery of such archeological and paleon- 
tological data and materials as will be lost through the construction 
of dams and the creation of reservoirs in many of the river valleys of 
the United States, continued its investigations throughout the year. 
The work was carried on in cooperation with the National Park 
Service and the Bureau of Reclamation, Department of the Interior, 
and the Corps of Engineers, Department of the Army, and was 
financed by the transfer of $73,800 from the National Park Service 
to the Smithsonian Institution. These funds were provided in 
part by the National Park Service and in part by the Bureau of 
Reclamation. 
Most of the work in the field was of a reconnaissance or survey 
nature, with only a limited testing of sites where such was necessary 
to determine their extent and character. In a few cases, however, 
actual excavations were undertaken. The activities involved 18 States 
and 88 reservoir areas. By the end of the year the number of reser- 
voir basins surveyed, since the first parties started in July 1946, totaled 
85. Their distribution is: Virginia 1, West Virginia 2, Georgia 2, 
Tennessee 1, Oklahoma 2, Texas 5, Colorado (outside of the Missouri 
Basin) 4, California 138, the Missouri Basin (7 States) 50, and the 
Columbia Basin (4 States) 15. Those where surveys were under 
way but not completed by June 30 are not included in this summary. 
In the various areas visited 1,576 sites were noted and recorded and of 
that number 250 have been recommended for extensive excavation. 
The excavations completed or in progress on June 380 were: New 
Mextco 1, Wyoming 1, Nebraska 1, South Dakota 1, North Dakota 1,
