Your question is too broad for us to address in any detail. You do not indicate under what circumstances such a breakwater would be constructed or subsequently dislodged, or what parties might be involved in authorizing it, constructing it, maintaining it, or causing it to be constructed or maintained. Issues of governmental immunity might also be relevant. See Texas Tort Claims Act, Civ. Under the circumstances addressed, where title to submerged littoral land is in the state, raising the land above the tideline by artificial means does not effect a transfer of title to the adjacent upland littoral property owner.
Title remains in the state.
Whether there would be liability for damages or other relief from harm caused by a dislodged breakwater would depend on the facts of the particular case. Footnotes FN1 See footnote 2. Lakefront, supra, at 608-09. The Fisher and Fitzgerald cases held that title to land was not lost to the state when the land became submerged. Your question assumes that title to the submerged land in question has been lost to the state, and we address here only the issue whether, once title is lost by submergence, it can be regained by raising the land again by artificial means above the high tide line.
