Abstract:

The report includes a review of the general geologic setting of the Ouachita River Valley between Ouachita City, Louisiana, and Arkadelphia, Arkansas, as well as more detailed interpretations and geological maps and sections of the alluvial valley between Ouachita City, Louisiana, and Camden, Arkansas. Within the alluvial valley, construction of new locks and dams is planned at Felsenthal and Calion, Arkansas, as part of the general navitation and flood-control program for this part of the Ouachita River Valley. Ultimately, the construction program, together with additional channel improvements, will provide a navigable channel with a minimum depth of 9 feet and a minimum bottom width of 100 feet as far north as Camden, Arkansas. This memorandum presents analyses developed from review of literature, study of aerial photographs, consultation with personnel of the U. S. Geological Survey Little Rock, Arkansas, preparation of topographic profiles, and study of boring data obtained by the Corps of Engineers, State Highway Departments of Louisiana and Arkansas, water-well drillers, and petroleum exploration contractors. Interpretations are made of the geologic setting, the stratigraphy, processes of sedimentation, and the influence of structural deformation on the alluvial sediments. These data are of a regional reconnaissance nature and provide only a background for the planning of engineering activities in the valley specific construction sites should be evaluated through more detailed foundation investigations.
