"The purpose of this report is to present the results of a study of the performance of the three relief well systems [along the Missouri River] during the July 1951 and April 1952 floods, and to compare their performance with design predictions. [...] The report includes observed uplift and well-flow data, descriptions of relief well operations during the floods, and an analysis of the effectiveness of the well systems together with discussion and comments on several experimental and test wells" (p. 2).
