Water resources - Allocation and Use - Western Australia
Basin and Surface Water Management Area: Esperance Coast
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.

What are the uses of surface water in Esperance Coast and to what is it allocated?
| Use type | Diversion Volume (ML/yr) | Allocation (ML/yr) | Diversion: Alloc (%) |
|---|---|---|---|
| Total | 211 | 258 | |
| Irrigation | 26 | 26 | 100 |
| Rural | 131 | 131 | |
| Urban / Industrial | 101 | 54 | 53.47 |
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 Esperance Coast?
| Total use | ML/yr | % |
|---|---|---|
| Surface water - from this area | 211 | |
| Surface water - imported into this area | no data |
