What are tiers?
Tier 1
Estimate using own judgement and observations
Tier 2
Estimate using third-party professional estimates or public data
Tier 3
Model or measure based on site-specific surveys/sampling, remote or in-field sensing, laboratory analysis, etc.
Example data sources
Internal records
Third-party data sources
Data on aggregated surface water resources extracted for Australian river regions are available at the Bureau of Meteorology – National Water Account.
Site-specific measurements or model outputs

What are tiers?
Tier 1
Multiply physical flow quantity by estimated monetary value per unit
Tier 2
Multiply physical flow quantity by estimated monetary value per unit
Tier 3
Multiply physical flow quantity by estimated monetary value per unit
Example data sources
Internal records
Third-party data sources
Site-specific measurements or model outputs
Notes
The value of the water resources asset (as opposed to the value of the physical flow of natural inputs from the asset) can be estimated based on the market price of similar water entitlements/offtake licences (where applicable), or estimated based on third-party valuation, less extraction costs.
