Murray–Darling Basin Authority

Three of Australia’s

longest rivers are

within the basin

Darling – 1545 km

Murray – 2530 km

Murrumbidgee – 1485 km

Flow contributions

vary from region to

region

Contributions to flows through Murray Mouth:

• Darling (and tributaries) 17%

• Murray (and tributaries) 83%

1,000,000 square

kilometres, covering

areas of 4 States and

1 Territory

The basin is home to:

40% of Australia’s farms

70% of Australia’s irrigated land

2006 had the lowest inflows in Australia’s recorded history

2010 saw widespread flooding across the Basin

On average there are many more dry years than wet

Seasonal inflows

reform

What’s in the Basin Plan

• Sustainable Diversion Limits (SDLs)

• Water resource planning

• Environmental watering

• Groundwater

• Water trading rules

Limit Adjustment

Mechanism (SDLAM)

SDL Adjustment proposals

Basin state governments are

working with communities and

stakeholders to develop

projects that achieve equivalent

environmental outcomes with

less water

Consultation process

• We will be holding meetings through September on the SDL

adjustment mechanism and other Basin Plan updates

• The regional meetings will be followed by a formal submission

period in October on the draft adjustment determination

• Following consideration of submissions the MDBA draft

determinations will then go to the Minister on 15 December
