; or (BB) an artificial dike, an artificial barrier, or a similar artificial structure, if that structure allows for a direct hydrologic surface connection between the wetland and the body of water described in clause (i), (ii), (iii), or (iv) of subparagraph (A) during a typical year, such as through a culvert, flood or tide gate, pump, or similar artificial feature. (II) Effect of roads and other structures For the purposes of subparagraph (A)(v), the division of an adjacent wetland by a road or similar artificial structure does not prevent the adjacent wetland in its entirety from being a navigable water or water of the United States if the road or similar artificial structure allows for a direct hydrologic surface connection through or over that structure in a typical year. (ii) Body of water subject to the ebb and flow of the tide (I) In general The term body of water subject to the ebb and flow of the tide means a body of water that rises and falls in a predictable and measurable rhythm or cycle due to the gravitational pulls of the moon and sun. (II) End of influence For purposes of this clause, a body of water described in subclause (I) ends when the rise and fall of the water surface can no longer be practically measured in a predictable rhythm due to masking by hydrologic, wind, or other effects. (iii) Ditch The term ditch means a constructed or excavated channel used to convey water. (iv) Ephemeral The term ephemeral means surface water flowing or pooling only in direct response to precipitation, such as rain or snow fall. (v) High tide line (I) In general The term high tide line means the line of intersection of the land with the surface of a body of water at the maximum height reached by a rising tide. (II) Inclusion The term high tide line includes the maximum height reached by a spring high tide or other high tide that occurs with periodic frequency. (III) Exclusion The term high tide line does not include the maximum height reached as a result of a storm surge in which there is a departure from
