Ohio Rev. Code § 721.04
Any municipal corporations within the limits of which there is included a part of the shore of the waters of Lake Erie may, in aid of navigation and water commerce, construct, maintain, use, and operate, piers, docks, wharves, and connecting ways, places, tracks, and other water terminal improvements with buildings and appurtenances necessary or incidental to such use, on any land belonging to the municipal corporation held under title permitting such use, and also over and on any submerged or artificially filled land made by accretion resulting from artificial encroachments, title to which is in the state, within the territory covered or formerly covered by the waters of Lake Erie in front of littoral land within the limits of such municipal corporation, whether such littoral land is privately owned or not.
Any such municipal corporation may, by ordinance, subject to federal legislation, establish harbor lines and other regulations for such territory and prohibit the placing, maintaining, or causing or permitting to be placed therein any unlawful encroachments on such territory.
The territory to which this section applies is limited to that within the limits of the municipal corporation and extending into Lake Erie to the distance of two miles from the natural shore line. For all purposes of government and exercise of such powers the limits of any such municipal corporation shall be held to extend out, in, over, and under such water and land made or that may be made within such territory. This section does not limit the now existing boundaries of any municipal corporation. Where two municipal corporations have upland territory fronting on such waters, and there is a conflict because of the curve of the shore line or otherwise as to such two mile boundary, the boundaries of each such municipal corporation may be determined by agreement between the municipal corporations concerned.
All powers granted by this section shall be exercised subject to the powers of the United States government and the public rights of navigation and fishery in any such territory. All mineral rights or other natural resources existing in the soil or waters in such territory, whether now covered by water or not, are reserved to the state.
