Summary

Portrait of John Catron John Catron Jones v. Soulard — Opinion of the Court

Above the ebb and flow of the tide, no river of England is navigable at all. In inquiring into the definition of navigable streams in that country, therefore, it was found that they were correctly described to be those in which the tide ebbed and flowed. But navigability is the principal thing; the flowing of the tide is a mere incident. When, therefore, we find that there are navigable waters in America, or elsewhere, not flowed by the tide, we seek other definitions of navigable water, the flowing of the tide being no longer a test.

This impatience merely marks the revolt of the judicial sense from the proposition, that any improvement can be made upon the legal definition which, in one sense, confines the term 'navigable' to tide-water. For as all rivers above tide-water depend for their navigability upon the rain which is drained into their beds, the degree to which the effect of the rain upon the volume of the stream is directly observable really makes no difference in principle.

Portrait of John Catron John Catron Jones v. Soulard — Opinion of the Court

So small a proportion of water navigable, in fact, is to be found above the tide in England, that no one is in danger of being misunderstood when he states the rule, without the qualifications which technical, literal accuracy requires, and says, generally, that in England rivers are navigable as far as the tide ebbs and flows, and no further, and that tide-water and navigable water are convertible terms in that country, the exceptions being too trifling to affect the general rule.
