(1) The volume of water moved by Macquarie Generation or its successor, from the Barnard River to Glenbawn Dam water storage shall be calculated and administered as set out in this clause and shall be held in a Barnard Reserve account.

(2) The volume of water held in the Barnard Reserve account at any time may not exceed 60,000 megalitres.

(3) Subject to subclause (2), the Barnard Reserve account is to be credited with the volume of water moved from the Barnard River to the Hunter Water Management Area, less any transmission losses between the point of entry of the water into the Hunter Water Management Area and its point of entry into the Glenbawn Dam water storage.

(4) The Barnard Reserve account shall be debited by the volume of water released from the Glenbawn Dam water storage to supply orders for water from the Barnard Reserve account, placed by Macquarie Generation or its successor.

(5) The volume released from the Glenbawn Dam water storage to supply orders from the Barnard Reserve account shall be the volume ordered plus the volume of transmission loss assessed to be associated with the delivery of the order from Glenbawn Dam to the point of extraction from this water source.

(6) When Glenbawn Dam spills, either over the spillway or by release from the flood mitigation zone, the volume of water held in the Barnard Reserve account is to be debited by the lesser of:

(a) the volume of spill, and

(b) the volume remaining in the Barnard Reserve account.

(7) Evaporation of Barnard Reserve account water held in the Glenbawn Dam water storage is to be assessed and debited from the account.
