Portrait of Stephen Johnson Field Stephen Johnson Field State of Indiana v. Kentucky — Opinion of the Court

Wherever the river is a boundary between states, it is the main, the permanent river, which constitutes that boundary; and the mind will find itself embarrassed with insurmountable difficulty in attempting to draw any other line than the low-water mark. When the state of Virginia made the Ohio the boundary of states, she must have intended the great River Ohio, and not a narrow bayou into which its waters occasionally run.

This is a natural boundary; and, in establishing it, Virginia must have had in view the convenience of the future population of the country. When a great river is the boundary between two nations or states, if the original property is in neither, and there be no convention respecting it, each holds to the middle of the stream. But when, as in this case, one state is the original proprietor, and grants the territory on one side only, it retains the river within its own domain, and the newlycreated state extends to the river only. The river, however, is its boundary.

That vast changes should be made in the channel of that river from the volume of water thus received, and its impetuous flow at certain seasons, wearing away its banks, deepening some portions of the stream, and filling up others, was not surprising; and that, where large vessels at one time could easily float should have become dry ground many years afterwards was but the natural effect of the tremendous forces thus brought into operation.
We have not deemed it important to take up the testimony of each of the numerous witnesses produced in the case by the states of Indiana and Kentucky.
