drainage subbasin the information on all is included in a single report, 
so that the 97 mimeographed pamphlets contain information on some 
130 of the reservoir projects. In addition to the archeological papers, 
one comprehensive report on the paleontological problems in the 
Missouri Basin was also issued. More detailed technical reports 
completed for a number of projects have appeared in scientific journals 
or are awaiting publication. 
The distribution by States of all the reservoirs investigated, as of 
the close of the fiscal year, is as follows: California, 16; Colorado, 23; 
Georgia, 2; Idaho, 9; Llinois, 2; Iowa, 3; Kansas, 6; Minnesota, 1; 
Montana, 5; Nebraska, 16; New Mexico, 1; North Dakota, 13; 
Oklahoma, 5; Oregon, 12; South Dakota, 9; Tennessee, 1; Texas, 
10; Virginia, 1; Washington, 9; West Virginia, 2; Wyoming, 8. Exca- 
vations completed during the year were: Colorado, 1; Nebraska, 1; 
North Dakota, 1; Oklahoma, 1; Oregon, 1; Washington, 1. In a 
number of cases the digging was started in the previous fiscal year 
and continued over into fiscal 1949. Other States where excavations 
were made in prior years are: Kansas, 1; New Mexico, 1; Texas, 1; 
and Wyoming, 1. 
As has been the case since the start of the River Basin Surveys 
program, staff men in the field received full cooperation from repre- 
sentatives of the National Park Service, the Bureau of Reclamation, 
the Corps of Engineers, and various State agencies. ‘Temporary 
office and laboratory space was provided at some of the projects, 
transportation and guides were furnished at others, and in several 
instances labor and mechanical equipment made available by the 
construction agency materially increased excavation operations. 
Had it not been for this assistance it would not have been possible to 
accomplish all that was done during the year. The National Park 
Service was primarily responsible for obtaining the funds which sup- 
ported the program and continued to serve as the liaison between the 
Smithsonian Institution and the other governmental agencies, both 
in Washington and through its several regional offices. The untiring 
efforts of Park Service personnel played a large part in furthering the 
progress of the program as a whole. 
The main office in Washington had general direction and super- 
vision over the work in Oklahoma, Texas, Minnesota, North Dakota 
(in the drainage of the Red River of the North), Iowa, Illinois, Colo- 
rado (outside of the Missouri Basin), and California. In the Missouri 
Basin, direction of the program was from a field headquarters at Lin- 
coln, Nebr., where all the materials collected by the survey and exca- 
vation parties were also processed. Activities in the Columbia Basin 
were supervised from a field office located at Eugene, Oreg.
