Preface: In September 1940 the Mississippi River Commission initiated a general study of the phenomena of underseepage and its control along Lower Mississippi River levees. The study was prompted by the occurrence of heavy underseepage and sand boils along numerous reaches of these levees during the 1937 flood. The results of this investigation, which utilized the combined efforts of the Memphis, Vicksburg, and New Orleans Districts and the U. S. Army Engineer Waterways Experiment Station (WES), are contained in WES TM No. 3-424, Investigation of Underseepage and Its Control, Lower Mississippi River Levees, October 1956. Appendices A through D, describing studies related to the problem of underseepage, were bound with the report. This report, Appendix E, contains an analysis and summary of piezometric data obtained during the 1961 high water. The relatively high river stage which occurred in 1961 provided an opportunity for checking the previous high-water analysis and determining whether any significant changes in seepage boundary conditions had occurred since that time. The study reported herein was authorized by the Mississippi River Commission in 1st endorsement dated 16 June 1961 to WES letter dated 1 June 1961, subject "Status of Soils Division Projects for MRC and 1MVD for FY 1961 and Request for Funds for Projects for FY 1962." The piezometric data obtained during the 1961 high-water period were furnished by the Memphis, Vicksburg, and New Orleans Districts. The analysis of data contained herein was made by Messrs. W. C. Sherman and C. C. Trahan, and the report was prepared by Mr. Trahan under the general direction of Messrs. W. J. Turnbull, W. G. Shockley, J. R. Compton, and W. C. Sherman, Soils Division, WES. Director of the WES during the course of this investigation was Colonel Alex G. Sutton, Jr., CE, and Technical Director was Mr. J. B. Tiffany.
