Abstract : The course of the mighty Ohio River has changed many times during the eons of geologic history, but the 981-mile long course of the Ohio as it existed in 1975 remained very much the same as it was when European explorers first discovered the river about three centuries ago. But doubtless these early explorers, were they to revisit the Ohio Valley in 1975, would not recognize the modem Ohio River and many of its tributary streams as being the same rivers they viewed in the seventeenth century, for between 1675 and 1975 a revolutionary transformation occurred in the Valley and on the rivers. In 1675 the Ohio Valley was, for the most part, covered by virgin forests and dense vegetation; the only human habitations were small, isolated Indian villages; and the sole commerce on Ohio Valley streams was a limited traffic carried on in primitive canoes and dugouts. The Ohio River and its tributaries were wild, scenic rivers, alternately calm and turbulent, subject to great fluctuations ranging from less than a foot deep at extreme low water to more than seventy feet deep at flood time. While these uncontrolled streams were doubtless quite beautiful and clear-running rivers, the many obstructions in their channels, notably the limestone ledges at the Falls of the Ohio, made even primitive navigation hazardous; and the wide range of stream fluctuations from low water to flood stages made living and working on their banks perilous, even to the sparse Indian population dwelling in the flood plains.
