Wat. Code, § 257

The director may execute all deeds or conveyances necessary to convey any real property or interest therein to be sold or exchanged under the provisions of this code. He may insert in any such deed or conveyance such conditions, covenants, exceptions and reservations as in his opinion are in the public interest or may convey in fee simple absolute. All statutes relating to state lands or to reservations of minerals therein or to reservations of rights to prospect for or mine or remove such minerals are inapplicable to lands heretofore or hereafter acquired by the State or conveyed by the State pursuant to the provisions of this code or pursuant to the provisions of previously existing statutes codified in this code, and no such statute in respect to state lands hereafter enacted shall be applicable thereto unless the Legislature expressly so declares.

It shall be conclusively presumed in favor of any purchaser for value and without notice of any real property or interest therein conveyed pursuant to the provisions of this code that the department acted within its lawful authority in acquiring the property, and that the director acted within his lawful authority in executing any deed or conveyance or lease authorized by this code.
