The Secretary is authorized to convey to States or their political subdivisions under the Recreation and Public Purposes Act (44 Stat. 741 as amended; 43 U.S.C. 869 et seq.), as amended, but without regard to the acreage limitations contained therein, unsurveyed islands determined by the Secretary to be public lands of the United States. The conveyance of any such island may be made without survey: Provided, however, That such island may be surveyed at the request of the applicant State or its political subdivision if such State or subdivision donates money or services to the Secretary for such survey, the Secretary accepts such money or services, and such services are conducted pursuant to criteria established by the Director of the Bureau of Land Management. Any such island so surveyed shall not be conveyed without approval of such survey by the Secretary prior to the conveyance.
No conveyance pursuant to this section shall be used as the basis for determining the baseline between Federal and State ownership, the boundary of any State for purposes of determining the extent of a State’s submerged lands or the line of demarcation of Federal jurisdiction, or any similar or related purpose.
