Water Modelling-Modelled Data-Annual Permitted Take (APT)-Castlereagh

Annual permitted take (APT) is a critical component of sustainable resource management, balancing water resource utilisation with ecosystem preservation. The dataset contains modelled APT data for the Castlereagh region, developed by the NSW Department of Climate Change, Energy, the Environment and Water, with a last update timestamp of 2026-05-12 16:28:29.280108.

Use Cases

• Track compliance with sustainable diversion limits (SDLs) based on the APT calculation method described.
• Model water availability scenarios based on described inputs like irrigated crop area and storage operations.
• Analyze water entitlement holders' distribution and use patterns as mentioned in the configuration estimates.
• Calculate the cumulative difference in water take for SDL compliance tracking from the 2019-20 water year.

Strengths

• Enforced since July 2019, providing a regulatory baseline for water take.
• Models are configured using specific estimates including irrigated crop area and storage operations, as detailed in the description.
• Last updated timestamp is precisely recorded: 2026-05-12 16:28:29.280108.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au, focusing on the Castlereagh region and Murray-Darling Basin.
