An agency shall maintain detailed records regarding its operation of any reservoir regulated pursuant to this Part. Such records shall be maintained at the agency field offices at each such reservoir and at the office of the agency reservoir releases manager. At a minimum, such records shall specify the amount of water released daily from each such reservoir, the amount of water diverted daily from each such reservoir, and the amount of water contained daily in each such reservoir. Not later than 45 days following the end of any calendar month, the agency reservoir releases manager shall provide to the department reservoir releases manager a summary of such records for that calendar month. Such monthly summary shall be in sufficient detail for the department to determine whether the agency's operation of each such reservoir during the preceeding month complied with the provisions of this Part. The department shall have the opportunity, after reasonable notice, to inspect such detailed records of the agency.
