Modelling supported planning and real-time decision making during the delivery of environmental water at a number of icon sites. This was through the provision of information concerning flow management, inundation extents, water quality risks and water accounting. Validation and recalibration of a number of models occurred with the input of measured data from the 2014-15 watering events. These processes help to ensure and maintain model accuracy and usefulness. Relevant international agreements Principle 9: TLM environmental watering actions are undertaken principally at the six icon sites. Many of these sites are listed under the international Ramsar Convention on Wetlands. Environmental watering supports many aspects of the Ramsar ecological description for these sites. Principle 10: Other management and operational practices Principle 11: Management of water for consumptive use, consistent with achieving environmental objectives where possible TLM’s regular consultation with MDBA and state-based river operators ensured that the management of water for consumptive use was considered in the delivery of TLM environmental water. In 2014-15, the River Murray System was operated at channel capacity in the mid reaches of the system for large periods of time to meet system demands, which included the delivery of large volumes of environmental water to South Australia. In this context it was a challenging year to improve environmental attributes and ecosystem functions and processes throughout much of the river, and particularly at locations like the Barmah Choke. Despite the challenging circumstances in 2014-15, the Authority continued to manage water for consumptive use, where possible, in ways that contributed to the environmental objectives of the Basin Plan.
