Daily river flows (ML/day) for a subset of river gauges throughout the Murray-Darling Basin with a modelled estimate of the contribution of Commonwealth environmental water. The evaluation of flow regimes is based on comparison of streamflow recorded at these gauges for the water year with streamflow that would have occurred in the absence of the Commonwealth water program. The Commonwealth environmental water contribution is estimated using a baseline modelling approach based on either point derivation, water accounting, and water planning information provided by CEWH, WaterNSW, GMW, and MDBA.

Data for 2014 – 2017 also includes an estimate of what flows would have been in the absence of river regulation (Flow Category = PRE). The modelling for these values was discontinued during the LTIM project in 2017.

The CEWH’s Flow-MER program examines the contribution of Commonwealth environmental water to the environmental objectives of the Basin Plan 2012 (Basin Plan) and is assisting the CEWH to demonstrate environmental outcomes and adaptively manage the water holdings. Monitoring and evaluation is 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

Compiled by the Flow-MER Basin scale project.

2014-2019 data based on information from the Long Term Intervention Monitoring (LTIM) project.
