Dear Sir:

Your question is whether under Tennessee's natural flow rule, a landowner is liable for flooding caused by vegetative growth in a watercourse that crosses his land?

That is a surprisingly difficult question, but the answer appears to be no.

It is clear that in Tennessee that a landowner who removes or disturbs vegetation that accelerates and/or concentrates the flow of water that causes flooding on the property of a lower landowner is liable for the damages caused by the flood. But as you undoubtedly already know (or you would not have asked the above question) the Tennessee cases citing the natural flow rule repeatedly declare that the landowner who creates an "artificial impediment" to the natural flow is liable for flooding that arises therefrom. The Tennessee cases involving the impediment of the natural flow deal with dams, drainage tiles, railroad trestles, and other manmade impediments to the natural flow of water. In one case, Chicago, M & G.R. Co.v. Wheeler, 1 Tenn. App. 100 (1925), the court did mention trees and other vegetation growing in the ditch in question this way:

Defendant ' s undertook and did show that at one place in the ditch north of the trestle, and on or near the land cultivated by the plaintiff, one or two trees were growing in the ditch and there were certain vines and vegetation growing in same. But as we understand the record, the main break in the side of the ditch and through which the water came that caused the material damage to the plaintiff ' s crop was between the trees and the trestle, so that the trees would tend to minimize rather than aggravate the overflow. In any event, it was a question for the jury as to whether the overflow was caused by the trestle or by their obstructions in the ditch. There is in the record material evidence that it was caused by the trestle, and the jury having accepted that view of the matter, we are bound by its findings. [At 1925 WL 1856]

We are not given a clue what would have happened in that case if the trees and other vegetation in the ditch had been the cause of the flooding, rather than the trestle, except that the court stated the familiar "artificial impairment" rule:

All lands, therefore, are of necessity burdened with the servitude of receiving and discharging all waters which flow down to them from lands on higher levels, and if the owner or occupier of the lower lands interposes artificial impediments in the way of the natural flow of the water across or through his lands, and by so doing causes the higher lands to be flooded, he is responsible for the infringing on the natural right of the possessor of such higher land to the natural outfall and drainage of the soil, unless he has gained a right to pen back water by contract, grant, or prescription. [At 1925 WL 1856]

I am enclosing Law of Water Rights and Resources, ' 3.16, entitled, Waters subject to riparian rights 'Flood waters' common law rules. In the third paragraph of that treatment, I have underlined what appears to be the rule about vegetation (and even a beaver dam) in other jurisdictions that follow the common law rule, although the North Dakota case cited therein, which I have also attached, involves a North Dakota Statute ' 61-01-07, which provided that:

If a person illegally obstructs any ditch, drain or watercourse, or diverts the water therein from its natural or artificial course, the person is liable to the party suffering injury from the obstruction or diversion for the full amount of the damage done, and, in addition, is guilty of a class B misdemeanor.

The court held that, "We conclude that N.D.C.C. ' 61-01-07 did not create a duty upon the Nelsons and Hendrickson to maintain the downstream watercourse by cleaning out, mowing, or burning natural growing vegetation.... " [See Bucholtz v. Barnes County Water Board, 775 N.W.2d 472 (N.D. 2008).] Such growth would not seem to be an "artificial impediment" under the common law natural flow rule either.

If you have found anything different, please let me know.
