Murray–Darling Basin
17.2 River outflow from the region
Supporting information
The volumetric value for the line item for the whole region for the 2012–13 year was 5,179,600 ML. This volume was the river outflow from South Australian Murray sustainable diversion limit (SDL) area to the sea estimated at the barrages.
The same volume applies as the river outflow from the Southern Basin. The river outflows from the Northern Basin into the Southern Basin were 1,705,320 ML. This was the inflow from the Barwon–Darling watercourse SDL area into the Lower Darling SDL area calculated at the upstream end of Menindee Lakes.
Quantification approach
Data source
Murray–Darling Basin Authority: flows through the barrages were sourced from HYDRO database, and flows into Menindee Lakes from the Barwon–Darling watercourse were sourced from water audit monitoring data received from New South Wales (24 March 2014) and stored in the HYDRO database.
Provided by
Bureau of Meteorology; and Murray–Darling Basin Authority.
Method
Flows into Menindee Lakes from the Barwon–Darling watercourse were based on metered discharge data and subsequent calculations.
Flows through the barrages were estimated based on the number of barrages open, the duration of their opening, and the flow rates across the barrages.
