Oregon Revised Statutes Public Lands § 273.265

(1) If application is made for the purchase of submersible lands, the applicant must cause such lands to be surveyed at the expense of the applicant by a surveyor, whose selection is subject to prior approval by the Department of State Lands. The survey must connect with and conform to adjacent surveys acceptable to the department, so far as practicable. The applicant must submit to the department, with the application, an accurate map of the lands applied for, showing the boundaries and stating the area. The map must be verified by the surveyor before an officer authorized by law to administer oaths.

(2) Each application to purchase submersible lands must, in addition to all other requirements, contain the applicant's statement that application is made with knowledge of the character of the land applied for and the title of the state thereto, and the waiver of the applicant of all claims upon the state for the return of the purchase price of the lands in the event that the lands, or any part thereof, do not belong to the state.
