Murray–Darling Basin
9.2 River inflow to region

The volumetric value for the line item at the end of the 2012–13 year was 451,000 ML for the Murray–Darling Basin (MDB) region. This is the discretionary flow made by Snowy Hydro to Murray and Tumut rivers in the Southern Basin of the region.

There was 1,705,320 ML inflow within the region (from the Northern Basin to the Southern Basin; this is not an inflow to the whole MDB region) during the 2012–13 year. The inflow was from the Barwon–Darling Watercourse sustainable diversion limit (SDL) area into the Lower Darling SDL area at Menindee Lakes.
