The Hydrology theme evaluates the contribution of Commonwealth environmental water to flow regimes and hydrological connectivity across the Basin, which also underpins the evaluation of ecological outcomes for other ecological indicators evaluated at the Basin scale (Fish, Vegetation, Ecosystem Diversity, Stream Metabolism and Water Quality, and Biodiversity).
The CEWO’s LTIM Project examined the contribution of Commonwealth environmental water to the environmental objectives of the Basin Plan 2012 (Basin Plan) and assisted the CEWO to demonstrate environmental outcomes and adaptively manage the water holdings. Monitoring and evaluation was focused in seven Selected Areas: the Junction of the Warrego and Darling rivers, Gwydir river system, Lachlan river system, Murrumbidgee river system, Edward/Kolety-Wakool river system, Goulburn River and Lower Murray River. These areas will continue to be monitored through the CEWO’s Monitoring, Evaluation and Research (MER) Program.
Data collected by monitoring at Selected Areas is used to evaluate local outcomes from watering and also contributed to the analysis and evaluation of Basin Plan objectives.
Please refer to the Murray-Darling Basin LTIM Project: 2018-19 Basin-scale evaluation of Commonwealth environmental water – Hydrology Report for the detailed method on data used for evaluation.
