We also consider the definitions of “flood” in treatises. Appleman’s Insurance Law and
Practice defines “flood waters” as “those waters above the highest line of the ordinary
flow of a stream, and generally speaking they have overflowed a river, stream, or natural
water course and have formed a continuous body with the water flowing in the ordinary
outside Louisiana. In Riche v. State Farm Fire & Casualty Co., an intermediate Louisiana
court interpreted a policy’s exclusion for “flood, surface water, tidal water or tidal wave,
overflow of streams or other bodies of water, or spray from any of the foregoing, all
whether driven by wind or not.” 356 So.2d 101, 103 (La.Ct.App.1978). The plaintiff in
Riche was fishing in a boat on a lake when a windstorm caused the boat to sink, id. at
reservoir.” Id. at 103-04. Riche, however, is of limited value in this case because its
determination was simply that a water-damage exclusion applied only to losses that
occurred on areas not normally covered by water (i.e., dry land) and not to a loss
occurring on a body of water. See id. at 103-04; see also Couch, supra, at § 153:54 (citing
Riche for the proposition that “[b]ecause a flood is generally understood to mean the
water falls within the language of the exclusion. Russell G. Donaldson, Annotation, What

Rubber Indus., Inc. v. Fed. Ins. Co., 84 A.D.2d 662, 444 N.Y.S.2d 321
levees. We agree that E.B. Metal’s rationale may not be fully applicable to this case on
this basis. Nevertheless, the plaintiffs have not directed us to any authority contradicting
the proposition that in the context of a broken dam, levee, or other similar structure,
