of the Water Account 2004-05. "Other" in respect of the estimated water consumption
comprises water use within the following industries:
- Water supply, sewerage and drainage services
- Electricity and gas
- Forestry and fishing
- Services to Agriculture
- "Other industries"

This page provides high level performance indicators of water management for the
Unincorporated Area - Tertiary Sedimentary Rock
groundwater management unit (GMU) based on information provided by the government
of
NT.
It provides answers to a range of questions of relevance to the National Water Initiative
(NWI), specifically in relation to:
- Groundwater management framework
- Water resource caps
- Surface water / groundwater interaction
- Sustainable groundwater yield
- Environmental allowances / provisions
- Groundwater diversions
- Groundwater entitlements
|
 |
Please note that a dash means that either the data was not
available, not provided or that the question was not relevant for a particular area.
Groundwater management framework
|
What is the status of the water management plan for this groundwater management
unit? |
Statewide policy |
|
If a final or draft plan has been written, what year was it completed?
|
- |
|
If a final or draft plan has been written, does it explicitly consider surface water? |
No |
|
If yes, how? |
- |
|

other public benefit outcomes? |
No |

Surface water / groundwater interaction
|
Are groundwater and surface water managed as an integrated water resource in this
groundwater management unit? |
No |
|
Reason or method: |
The connectivity is unknown |
Sustainable groundwater yield
|
The sustainable yield within this groundwater management unit for 2004/05 was: |
- ML |
|
The method used to determine the sustainable yield was: |
Simple analytical calculations |
|
Was the sustainable yield determined for the combined (i.e. surface water and groundwater)
water resources? |
No |
|
Is the cap considered to be at or below the sustainable yield of surface water? |
At |
|
If the cap is above the sustainable yield, are there management actions to bring
the cap down to sustainable yield? |
- |
|
How has the aquifer responded? |
- |
|
Does this aquifer trend require a management response? |
- |
|
What is the level of development relative to the sustainable yield? |
Low level of development |
