the year preliminary appraisal reports were completed for all the 

 reservoirs surveyed, and 23 reports were mimeographed for limited 

 distribution to the cooperating agencies. This makes a total of 120 

 such reports issued since the start of the program. The excavations 

 made during fiscal 1950 bring the total for areas where such work has 

 been done to 21 . Technical reports on the results of some of that work 

 have appeared in scientific journals, while the completed manuscripts 

 on others are now awaiting publication. Paleontological siu'veys have 

 been made in 100 reservoirs, 56 being those where archeological work 

 has also been done. The remaining 44 will eventually be visited by 

 archeological parties. Including the reservoir areas where archeo- 

 logical work remains to be done, the over-all total of reservoirs visited 

 is 224. 



The distribution by States of all the reservoirs investigated for 

 archeological remains as of June 30, 1950, is as follows: California, 20; 

 Colorado, 23; Georgia, 3; Idaho, 10; Illinois, 2; Iowa, 3; Kansas, 6; 

 Louisiana, 1; Minnesota, 1; Montana, 5; Nebraska, 16; New Mexico, 

 1 ; North Dakota, 13 ; Ohio, 2 ; Oklahoma, 5 ; Oregon, 24 ; South Dakota, 

 9; Tennessee, 1; Texas, 13; Virginia, 1; Washington, 9; West Virginia, 

 2; Wj^oming, 11. Excavations have thus far been made in: Cal- 

 ifornia, 1 ; Colorado, 1 ; Georgia, 1 ; Kansas, 1 ; Montana, 1 ; Nebraska, 

 1 ; New Mexico, 1 ; North Dakota, 2 ; Oklahoma, 1 ; Oregon, 1 ; South 

 Dakota, 2; Texas, 3; Virginia, 1; Washington, 3; and Wyoming, 1. 



Throughout the fiscal year the Kiver Basin Surveys received full 

 cooperation from the National Park Service, the Bureau of Keclama- 

 tion, and the Corps of Engineers, as well as various State agencies. At 

 some of the projects guides and transportation were furnished to staff 

 men in the field. At others, office and laboratory space was provided, 

 and in a number of cases labor and mechanical equipment were made 

 available by the construction agency. The assistance provided made 

 possible a greater accomplishment than would otherwise have been 

 possible had it been necessary for the River Basin Surveys men to rely 

 on their own resources. The National Park Service was primarily 

 responsible for procuring the funds necessary for carrying on the pro- 

 gram and also served as the liaison between the Smithsonian Institu- 

 tion and the other governmental agencies, not only in Washington but 

 through its several regional ofiices as well. 



General supervision and direction of the work in California, Texas, 

 Louisiana, Georgia, Ohio, and Virginia were from the main office in 

 Washington. The Missouri Basin program was carried on under the 

 direction of a field headquarters and laboratory at Lincoln, Nebr., and 

 the activities in the Columbia Basin were supervised by a field office 

 located at Eugene, Oreg.
