In order that the natural resources of Oregon in land, water and power may be utilized to the highest advantage of the people, complete cooperation between the state and federal authorities in controlling, investigating and developing these resources in the interest of the people of the state is essential. Therefore, the Water Resources Commission may, on behalf of this state, enter into a contract or agreement with any federal department or bureau having jurisdiction in such matters for the execution of such surveys and investigations and the preparation of such plans, specifications and estimates or other data by cooperation between the state and the federal department or bureau as will, in the judgment of the Water Resources Commission, approved by the Governor, be best suited to accomplish the purposes of ORS 542.010 to 542.050. However, in no case shall the proportion of expense to be borne by this state exceed the proportion to be borne by the other party to the contract or agreement.
