COMMUNITY DROUGHT INFORMATION SESSIONS, MAY AND JUNE 2019
Groundwater management and the impact of drought—major inland alluvial water sources
Groundwater management
• Aquifers store large volumes of water
• Long-term extraction = Long-term recharge
• High use due to a long-term dry period can lead to restrictions on use
Page 2
Water sharing plan rules
• Extraction and distance restrictions to manage local impacts
• Require new basic landholder rights bores to be drilled to sufficient depth to maintain long-term access
• Specify accounting rules—set maximum carryover, annual account limits
• Set trading rules—where and how much water can be traded between connected aquifers
Page 3
Page 4
Dry conditions since 2017 are affecting water resources
Groundwater sources—extreme event stages
Page 5
• No groundwater sources in NSW have reached drought stage 2
• We continue to use normal rules
How does drought affect groundwater resources?
• Groundwater is more drought-resilient than surface water
• Larger groundwater systems have higher buffer due to storage
• Stress comes from substituting from surface water supply, plus reduced recharge
• In drought-affected areas, the water levels in most monitoring bores are at below-average levels, corresponding with increased extraction and reduced recharge
Page 6
Increasing bore applications and groundwater trades
Substantial increase in applications for basic landholder right bores and for trade of groundwater allocations and aquifer access licences
All applications are assessed:
• extraction impact assessments—based on risk management approach
• hydrogeological assessment considers:
• impact on aquifer
• impact on other users—licensed & basic landholder rights
• impact on environment—groundwater dependent ecosystems and river
Page 7
Possible management options in response to declines in groundwater
• Reduced allocations in those systems that have exceeded the long term extraction limit for more than three years (or 5 years in some water sources)
• Section 324 (2) orders:
If it is necessary :
(a) to maintain or protect water levels in an aquifer,
(b) to maintain, protect or improve the quality of water in an aquifer,
(c) to prevent land subsidence or compaction in an aquifer,
(d) to protect groundwater-dependent ecosystems,
(e) to maintain pressure, or to ensure pressure recovery, in an aquifer,
Page 8
Possible management options in response to declines in groundwater, continued
within a specified area and for a specified period, the taking of water from that aquifer, or from any other aquifer that is above, below or adjacent to that aquifer, can be prohibited, or is subject to restrictions.
