The water-dependent asset register for the Namoi subregion is a simple and authoritative list of assets within the assessment extent that are potentially affected by changes in water due to coal seam gas and coal mining development.

The initial register that accompanied the Description of the water-dependent asset register for the Namoi subregion report was extracted from the Namoi subregion asset database in January 2015.

Since then, the asset database has been updated. Information has also been added about whether any part of each asset occurs within the zone of potential hydrological change defined for the assessment. Using the updated database, an updated water-dependent asset register was extracted on 30 June 2017 and the counts of assets below are from that register. The impact and risk analysis and the outcome synthesis use the asset information from the updated register.

Some assets cannot be publicly distributed or displayed by the Bioregional Assessment Program due to restrictions on the use conditions of the datasets that describe them. However, many of these datasets are available directly from their custodian. For more details, see the data dictionary included with the asset database.

Assessment extent

The assessment extent of the Namoi subregion is defined by the Namoi river basin, except in the east where it extends to the Hunter-Mooki Thrust fault. This additional area has been included in the assessment extent to make sure any potential impact from coal seam gas or coal mining development is considered as part of the bioregional assessment.

In the lower Namoi river basin, the impact of coal seam gas and coal mining development could extend across the Namoi alluvium into the Gwydir subregion. This area has been included in the Namoi assessment extent, again to make sure any potential impact from coal seam gas or coal mining development is considered.

Water-dependent assets

There are a total of 1889 water-dependent assets in the Namoi subregion assessment extent.

Ecological water-dependent assets

There are 1690 ecological water-dependent assets in the assessment extent for the Namoi subregion.

Economic water-dependent assets

There are 168 economic water-dependent assets in the Namoi subregion. They include water access rights.

Sociocultural water-dependent assets

There are 31 sociocultural water-dependent assets in the assessment extent for the Namoi subregion.

A separate report on Indigenous water assets in New South Wales is available. The report includes information relevant to this product and contributes to the bioregional assessment.
