Step 2: determine the management outcomes that apply to the resource availability scenario The broad management outcomes relevant to each RAS are determined using Table 2 (below). Detailed prioritisation decisions and real time management of environmental water will be based on reconciling water supply and ecological demand, consistent with the provisions of the environmental management framework set out in Part 4 of Chapter 8 of the Basin Plan and are not addressed by these guidelines.

Table 2: Management outcomes for each RAS Resource availability scenario Very dry Dry Moderate Wet Very wet Management outcomes Avoid irretrievable loss of or damage to, environmental assets: Avoid critical loss of species, communities, and ecosystems. Maintain critical refuges. Avoid irretrievable damage or catastrophic events. Allow drying to occur, where appropriate, but relieve severe unnaturally prolonged dry periods. Ensure environmental assets maintain their basic functions and resilience: Support the survival and viability of threatened species and communities. Maintain environmental assets and ecosystem functions, including by allowing drying to consistent with natural wetting-drying cycles. Maintain refuges. Maintain ecological health and resilience: Enable growth, reproduction and recruitment for a diverse range of flora and fauna. Promote low-lying connectivity. Support river and floodplain functions. Improve the health and resilience of ecosystems: Enable growth, reproduction and recruitment for a diverse range of flora and fauna. Promote higher connectivity. Support high-flow river and floodplain functions. Improve the health and resilience of water-dependent ecosystems: Enable growth, reproduction and large-scale recruitment for a diverse range of flora and fauna. Promote higher floodplain-river connectivity. Support high-flow river and floodplain functions.
