Surface Water Economic Assets Gippsland 20150430v02

Brief description

## **Abstract**

This dataset was derived by the Bioregional Assessment Programme from the following sources

1) Southern Rural Water Surface water "works" locations (xy)

2)Regs Category 6a supplied to the Bureau by DEPI under the Water Act 2008

3) A "one off" extract" of Unregulated licences (xy locations, use, entitlement volume)

You can find a link to the parent datasets in the Lineage Field in this metadata statement. The History Field in this metadata statement describes how this dataset was derived



This dataset is restricted - not for publication.



Note that there are many issues with licencing data that it difficult to model the situation on the ground

1) Use is only valid at the time of the registration of licence ( the licence may be traded and may change use which may not be recorded). Use is therefore only indicative at any point in time

2) Status - Which determines whether the "works" is active may also be out of date or not updated

Users are encouraged to use other sources to validate licencing data and also encouraged to take into account other fields included such as date etc

## **Purpose**

This dataset has been created to represent Surface Water Economic Entitlements spatially in the Gippsland Basin

## **Dataset History**

This dataset was derived by the Bioregional Assessment Programme using the following steps

1) Unreg Surface Water Licences DELWP Gippsland 20150301\t(0353426b-403d-4d4b-aac0-75afb55e1176) was geolocated using the "Make XY Event" function in ArcGIS with the projection VICGRID 94 (as indicated to use in source file)

2) This file was merged with the derived dataset: (SouthernRuralWater SW Locations with BOM RegsCat6Volumes Gippsland 20150430\t59f17548-3dbe-41a8-92f2-3b39ebbb0584) using the ArcGIS Merge Command

3) The "Feature Compare" command was used to find duplicate licence numbers in both files. Project team decided to keep records from "once off" DEPI Extract as these also contained uses. 966 duplicates found in data from SRW - This is because there are sometimes many locations for one licence in the SRW data.

4) Duplicate records were removed from SRW dataset leaving only 178 licences not found in DELWP extract.

5) Remaining records were merged into final dataset

6) Classification of uses of data in DELWP extract:





Domestic and stock\t Basic Water Right

Domestic and Stock\t Basic Water Right

Aquaculture\t Water Access Right

Dairy\t\t Water Access Right

Industrial or commercial\t Water Access Right

Intensive animal husbandry\t Water Access Right

Irrigation\t\t Water Access Right



178 records from SRW were all classified as Water Access Right as no use was found



Volumes:

The field that should be used to allocate volumes correctly by works is "Vol_combined" - this field contains Entitlement per works for SRW data and Entitlement Vol directly from DELWP extract



Note data has been kept in source prj GDA_1994_MGA_Zone_55
