Water resources - Allocation and Use - Tasmania
Basin and Surface Water Management Area: Pieman River
Introduction
The National Water Reform Framework requires the development of comprehensive systems of water allocations or entitlements, backed by separation of water property rights from land and clear specification of entitlements in terms of ownership, volume, reliability, transferability and, if appropriate, quality. In addition State and Territory agencies are required to undertake formal determination of water allocations or entitlements, including allocations for the environment as a legitimate user of water.
Water use estimates have been derived from a number of different methods including the use of licencing systems, information provided as part of the Australian Bureau of Statistics water account (with provider consent) and other information gathered from the State and Territory water agencies. In some cases water use was assumed to be the same as the allocation. For groundwater systems, it is well known that this assumption is often invalid (e.g. typically where use exceeds allocation significantly).
Options for conjunctive use are also described.
Please note: The tables set out below detailing Level 1 and Level 2 water use categories. The sum of the Level 2 water use volumes will not necessarily equal the total Level 1 water use volumes. This is primarily due to lack of more detailed water use data. However, where Level 2 use = Level 1 use then blank cells in the table does not indicate water use unaccounted for in these categories.
How has water used changed since 1985?

PLEASE NOTE
Changes since 1985:
Average yield between Review 85 and this Audit is different by greater than 10%. The difference would be reflected in different approaches adopted. However the amount contained in Review 85 appears to be grossly over estimated Unfortunately information on Review 85 was not well doucmented in the Review hence further comments on reasons fo the difference cannot be made.
Divertible yield for the SWMA was not recalculated for the this Audit due to time constraints. It has been assumed that the estimates for 1985 still stand as the majority of the areas catchments have not had significant projected infrastructure developments since that time. This particularly applies to this SWMA. However it must be stressed that the background information for the Review 85 cannot be found to enable the estimate to be checked in line with current methods for determining divertible yields.
What are the uses of surface water in Pieman River and to what is it allocated?
| Use type | Diversion Volume (ML/yr) | Allocation (ML/yr) | Diversion: Alloc (%) |
|---|---|---|---|
| Total | 8,190 | no data | |
| Urban / Industrial | no data | 8,190 | |
| - domestic | no data | 390 | |
| - industrial | no data | 7,800 |
Allocation for each SWMA represents the volume of the management area's surface water resources allocated for use both within the basin and for use in other SWMAs. The volume diverted is the total volume of the SWMA's surface water resources diverted for use both within the management area and for export to other management areas.
What are the sources of water within Pieman River?
| Total use | ML/yr | % |
|---|---|---|
| Surface water - from this area | 8,190 | 96 |
| Surface water - imported into this area | no data | |
| GMU: Unincorporated Area - West | 257 | 3 |
| GMU: Unincorporated Area - Central South East | 0 | 0 |
| GMU: Burnie | 86 | 1 |
PLEASE NOTE :
Options for conjunctive use:
Not envisaged.
