TLM framework for decision making Environmental management objectives The Living Murray uses water resource scenario planning to outline the potential watering activities which may occur during the year, considering water availability and icon site water requirements. This informs the planning for the delivery of TLM environmental water and offers a level of adaptability to changing conditions. Ecological watering objectives are defined for four different water resource scenarios Extreme Dry, Dry, Median and Wet/Very Wet (Table 5). — Table 5 Proposed ecological watering objectives under different water resource scenarios Objective Extreme dry Dry Median Wet/very wet Overarching Avoid catastrophic Improved capacity Protect ecological Improved health objective loss/maintain for recovery health and resilience capacity for potential recovery Ecological Avoid irretrievable Ensure priority Ecological health Improve the watering loss of key river reaches and of priority river health and objectives environmental assets wetlands have reaches and resilience of maintained their wetlands have aquatic basic functions been protected or ecosystems improved Management Avoid critical loss of Maintain river Enable growth, Enable growth, objectives species, functioning with reproduction and reproduction and communities and reduced small-scale large-scale ecosystems reproductive recruitment for a recruitment for a Maintain key refuges capacity diverse range of diverse range of Avoid irretrievable Maintain key flora and fauna flora and fauna damage or functions of high Promote low-lying Promote higher catastrophic events priority wetlands floodplain-river floodplain-river Manage within dry connectivity connectivity -spell tolerances Support medium Support high flow Support flow river and river and connectivity floodplain floodplain between sites functional functional processes processes Management Water refugia and Water refugia and Prolong Increase actions sites supporting sites supporting flood/high-flow flood/high-flow species and threatened species duration at key duration and communities and communities sites and reaches extent across Undertake Provide low flow of priority assets priority assets emergency watering and freshes in Contribute to the Contribute to the at specific sites of sites and reaches full-range of full range of flows priority assets of priority assets channel flows including Use carryover Use carryover Provide carry volumes to maintain volumes to over to accrue Use carryover to critical needs maintain critical water for large provide optimal needs watering events seasonal flow patterns in
