The Toorale water management infrastructure operating and maintenance plan (OMP) provides a framework for the operation and maintenance of water infrastructure on Toorale National Park and State Conservation Area (Toorale).
Management of river flows through Toorale aims to balance the needs and values of local environmental assets and the downstream riverine environment, while minimising impacts to other park and water users.
The OMP addresses relevant statutory and planning matters to ensure that operation and maintenance of the structures is compliant with all of these instruments. It was approved by Department of Planning and Environment – Water (DPE Water) in June 2022.
The OMP describes how the regulating structures will be operated to prioritise environmental assets across a range of river flow scenarios and antecedent conditions. It outlines the management of environmental and other risks, the circumstances when either the Darling River or Warrego floodplain may be prioritised, and guides decisions before, during and post flow events. It does not prescribe the management of individual events, which will be informed by the context and conditions in which the event occurs and in accordance with Annual Environmental Watering Plans prepared in consultation with an Environmental Water Advisory Group (EWAG).
The OMP adopts an adaptive management approach to give flexibility for a range of river flow scenarios and to be responsive to flow and ecological observations (including emerging risks and/or realised benefits) during an event.
The operation of structures on Toorale will be reviewed annually and following significant flow events, informed by monitoring and experience gained from each event and improved modelling and other inputs over time. Stakeholders will also have an opportunity to provide input into these reviews, primarily through the EWAG.
This OMP may be updated at any time to comply with the regulatory framework that is in place, with the approval of DPE Water.
A Fishway Management Plan is currently being developed and will be added to the OMP following testing and calibration of flows through the new structure at Boera by Department of Primary Industries – Fisheries (Fisheries).
