Basin-scale evaluation of 2019–20 Commonwealth environmental water: Synthesis.

Strategic management of Commonwealth environmental water by the Commonwealth Environmental Water Holder (CEWH) is key to achieving Murray-Darling Basin Plan 2012 objectives. The 3-year Basin-scale FlowMER Program evaluates the ecological responses to the delivery of Commonwealth environmental water to support legislative requirements under the Basin Plan, inform adaptive management, and support environmental water managers. This evaluation reports on Basin-scale outcomes from Commonwealth environmental water for the most recent water year (2019–2020) and cumulative outcomes since the beginning of the program in 2014. It assesses the contribution of Commonwealth environmental water to Basin Plan objectives, and provides considerations for adaptive management.
