Project 90-A Study of Factors Influencing the Financial Condition of Certain Utah Irrigation and Drainage Projects-was undertaken in 1928 as an intensified study of local areas. This study was divided among four departments, with a project leader for each particular phase of the study. These four project leaders, guided by the Station Director, have constituted a committee in immediate charge of this project. Subprojects and their respective leaders have been: A-Engineering and Engineering Economic Aspects, O. W. Israelsen; B-Soil Productivity Aspects, D. S. Jennings; C-Contributing Sociological Aspects, J. A. Geddes; and D-Economic Aspects, W. Preston Thomas.
