The city shall maintain detailed records regarding its operation of the Cannonsville, Pepacton and Neversink reservoirs. Such records shall be maintained at the city field offices at each such reservoir and at the office of the city reservoir releases manager. Such records shall at a minimum specify the amounts of water released daily from each such reservoir; the amount of water diverted daily into the west Delaware tunnel, the east Delaware tunnel or the Neversink tunnel from such reservoirs; and the amount of water contained daily in each of such reservoirs. Not later than 45 days following the end of any calendar month, the city 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 city's operation of each such reservoir during the preceding month complied with the provisions of this Part. The department shall have the opportunity, after reasonable notice, to inspect the city's detailed records.
