(b) Upon petition, made to a court in which a relevant judicial decree has been entered, by the owners or governing bodies of at least 15 percent of the conduits lawfully entitled to directly divert water from the streams or other sources of water supply in any service area, the court may appoint a public agency as watermaster under this part to replace the watermaster appointed by the department.

(2) This part shall apply to the service area for which a watermaster is appointed pursuant to subdivision (b) only to the extent determined by the court. (d) (1) If in response to a petition made to a court, the court appoints a watermaster in a service area in which the department previously appointed a watermaster, upon the appointment of the new watermaster becoming effective, the department shall not be responsible for carrying out any of the duties and obligations of this part, including any responsibility for the funding of the expenses of administration or distribution pursuant to Chapter 7 (commencing with Section 4200).
