Okla. Stat. tit. 82, § 82-105.6: Adjudication of rights - Suit

When the Board determines the best interests of the claimants to

the use of water from a stream system will be served by a

determination of all rights to the use of water of such system, the

Board may institute a suit on behalf of the state for the

determination of all rights to the use of such water and shall

diligently prosecute the same to a final adjudication. The cost of

such suit, including the costs on behalf of the state, shall be

charged against each of the parties thereto in proportion to the

amount of water rights allotted. Provided that after the effective

date of June 10, 1963, neither the bringing of such suit nor an

adjudication in such a suit shall be a condition precedent to the

granting of permits and licenses as authorized by this act.
