Summary: This report presents a study of the Lake Providence reach including that portion of the Mississippi River from the lower end of Mayersville revetment (1962 mile 494.6) to the lower end of Hagaman revetment (1962 mile 479.8). The purpose of the study is to analyze the effects of the Baleshed Landing Stone Dike system within the dike field proper and in the reaches immediately downstream. Construction of the dikes was terminated during February 1965. The report attempts to evaluate the changes in various channel characteristics during the period January 1964 to December 1965. The purpose, plan, and design of the dikes are described along with discussions of construction problems and the difficulties involved in the control or closure of flow through secondary channels and chutes. A comparison of the representative cross sections within the dike field, and of hydraulic factors and characteristics of selected ranges and reaches is presented in charts and profiles. These factors include area and depth relations, stage-discharge, and water surface profiles before, during, and after construction of the dikes. Sediment transport data and the relations of stream power and median grain size of the bed material to the bed form are indicated for this portion of the river. In conclusion, a candid discussion of the results of the study is given which summarizes some of the more pertinent channel stabilization problems in the Lower Mississippi River. Additional basic survey data requirements and the direction of continuing and future investigations are discussed. Finally, some pertinent questions and observations are given relating to the controlling principles involved in river mechanics and engineering.
