Basin-scale evaluation
Evaluating the contribution of Commonwealth environmental water
The Flow-MER Basin-scale evaluation assesses the contributions of Commonwealth environmental water to meeting the environmental objectives in Section 8 of the Commonwealth’s Basin Plan 2012 and the Basin-wide environmental watering strategy (the Strategy). The Basin-scale evaluation uses the approach, methods and data developed for the Long-Term Intervention Monitoring (LTIM), 2015–2019.
The Basin-scale evaluation reports on the environmental outcomes of delivering Commonwealth water each water year against 4 Basin Plan objectives: biodiversity, ecological function, water quality, and resilience. The evaluation is reported at the whole-of-Basin scale, including, in some cases, valleys where environmental outcomes from delivering Commonwealth environmental water are not actively monitored.
The Basin-scale evaluation is undertaken for 6 Basin Themes (Figure 1) based on ecological indicators developed for the LTIM and described in the Environmental Water Outcomes Framework (the Framework). While there is a line of sight to the Strategy, there is no explicit link between objectives in the Strategy and evaluation questions, as the Framework was developed before the Strategy was finalised.

The findings of the Basin-scale evaluation are summarised in an annual Synthesis report and complement findings from targeted intervention monitoring (for specific watering events) and evaluations undertaken for each of the 7 Selected Areas. A detailed evaluation of the environmental outcomes from the delivery of Commonwealth environmental water is presented in 6 thematic evaluation reports.
