Background to the Murray-Darling Basin (MDB)
Background to the MDB Plan
Commonwealth Water Act 2007
Water for the Future Program 2008
Proposed Basin Plan
Context

Content (with a focus on environmental flows)
Concluding Remarks
The Murray Darling Basin
Water management challenges
Overallocation
Groundwater use impact on surface water systems
Serious environmental degradation; reduced environmental flows & water quality
Loss of productivity & economic activity
Risks to community water supply
Severe & prolonged drought & conversely floods
Significant water related impacts due to climate change
Large and naturally variable basin
Multiple jurisdictions
Commonwealth Water Act 2007
Provides for integrated management of water resources
Enable Commonwealth in conjunction with States to manage
Basin’s water resources
Optimise economic, social and environmental outcomes
Environmental sustainability
Improve water security
Commonwealth Water Act 2007
Creation of new, independent Murray Darling Basin Authority
(MDBA)
Process for development of the Basin Plan
Establishment of the Commonwealth Environmental Water
Holder (CEWH)
Water information collection, analysis and distribution (by the
Bureau of Meteorology)
Audits by the National Water Commission
Water for the Future Program
A 10 year new $12.9 billion Australian Government fund
Four key priorities: taking action on climate change, using water
wisely, securing water supplies and supporting healthy rivers
Rural Water Use Efficiency ($5.8 billion)
Purchase of water for the environment ($3.1billion)
National Water Security Plan for Cities & Towns ($1.5 billion)
Improving water information ($450 million)
Commonwealth Environmental Water Holder
(CEWH)
Manages the water entitlements purchased by the
Commonwealth for the environment
Water purchased through the Water For the Future Program
should reduce the impact of new limits on diversions set by the
basin plan on existing water users
Murray-Darling Basin Authority (MDBA)
• Role/Functions
• Preparing the Basin Plan for Commonwealth Minister’s approval
• Accreditation of state water resource plans
• Measure, monitor and enforce compliance on water resources
• Engaging the community
• Some water system operations and natural resources management
Examples of Key environmental assets in MDB
Identify Key Environmental Assets (KEA)
Approach for environmentally sustainable level of take
Identify Indicator Assets (IA)
Determine Environmental Water
Requirements (EWR) for Indicator Assets
Determine Key Ecosystem Functions (KEF)

Requirements for Key Ecosystem Functions
Modelling, Review, Analysis, Expert Advice
Location, flow, duration, frequency, spells,
intervals – sets environmental demands in
hydrologic models
Based on Five Criteria: 1. Recognised
significance; 2. Natural, near natural, rare, unique;
3. Critical habitat (drought refuges, breeding
sites); 4. Threatened species; 5. Sites of high
biodiversity (total 2,442 KEA across MDB)
Key large representative floodplains, wetlands –
total 18 hydrologic indicator sites for 18 IA (a
subset of 2,442 KEA across MDB)
Focus on ‘in-channel’ functions and processes
(total 88 hydrologic indicator sites for KEF
across MDB)
Flow indicators examined as indication of KEF –
sets environmental demands in hydrologic
models
Environmentally Sustainable

What does the Basin Plan Mean for Water
Planning in Queensland?
The Basin Plan binds
- Basin State Agencies
- Infrastructure operators
- Holders of water access entitlements (industry)
Water Planning
- Qld will continue to plan, allocate and manage water resources within its borders but…
- Qld Water Resource Plans for MDB catchments will need to be accredited by the Commonwealth Minister responsible for water (with advice to be provided by the MDBA)
- Must comply with the Basin Plan
Concluding Remarks
Water is a scarce, finite, valuable resource
Strong governance and clear decision making are
important but difficult
The best decisions are underpinned by best
available knowledge and information including
R&D
Aim for transparency of and ‘whole of basin’
collaborative approaches to planning and
management processes
Pursue active stakeholder involvement and
understanding
Concluding Remarks (cont’d)
Test for consistency and coherence of policy
(e.g. institutional, entitlement, pricing, planning)
Remember principles of Ecologically
Sustainable Development and Triple Bottom
Line
Include adaptive management including
requirements for monitoring, reviewing and
reporting
Consider linking reform milestones with
incentives and sanctions
