Summary
The U. S. Army-Corps of Engineers conducted detailed surveys of the entire floodplain of the Ohio River from Pittsburgh PA to Powhatan Point, OH. An index sheet and a series of 280 charts were produced by the Ohio River Board of Engineers on locks and dams between 1911 and 1914 and revised in 1930. Each chart illustrates Ohio River bathymetry, topographic elevations, cultural and navigational features, land-use, property owners, lithologic composition of river bank and bar sediments, and subsurface lithologic data and, in some cases bedrock elevations, from river bank and river bottom borings. All borings are numbered from the Ohio River left bank to the right bank and occur in a line perpendicular to river flow direction. Boring top and bottom elevations were determined from the low water slope of the Ohio River Surveys of 1896-1906. Latitude and longitude coordinates, referred to the North American datum, were derived by connecting with primary triangulation stations established by other government bureaus.
