Lake Bistineau Land Title Stability Act This bill declares that the document titled "Dependent Re-Survey, Extension Survey and Survey of Two Islands, Sections 17, 29, and 30" (published in the Federal Register on February 27, 1969) shall not be considered to be, or serve as, a gross error determination and shall have no legal force or effect on the ownership of certain land surrounding Lake Bistineau in northern Louisiana. The meander lines recorded in the original survey of such land approved by the Surveyor General on December 8, 1842, shall be definitive for purposes of determining title to such land and two adjacent islands. The Department of the Interior shall prepare a disclaimer of any U.S. right, title, or interest in and to any such land that is located outside such meander lines and any omitted land that was in place, but not included, in the original survey.
