Before any proposed water management area is designated by the commission, the chairperson may conduct, cooperate with the appropriate federal or county water agency in conducting, or administer contracts for the conduct of, any scientific investigation or study deemed necessary for the commission to make a decision to designate a water management area. In connection with such investigation or study, the chairperson from time to time may require reports from water users as to the amount of water being withdrawn and as to the manner and extent of the beneficial use. Such reports shall be made on forms furnished by the commission.
