Water Modelling-Modelled Data-Long-term Average Annual Extraction Limit (LTAAEL)-Macquarie

NSW data contains modelled water flows at several gauges in the Macquarie river system, simulated by an annually extended Long-term Average Annual Extraction Limit (LTAAEL) model. The dataset is provided by the NSW Department of Climate Change, Energy, the Environment and Water to assess compliance with sustainable water extraction limits defined by water sharing plans. It was last updated on 2026-05-12.

Use Cases

• Assess regulatory compliance based on modelled long-term average annual extractions exceeding limits.
• Compare simulated flow scenarios based on the LTAAEL model with outputs from other models like the Annual Permitted Take (APT) model.
• Monitor river system sustainability based on the conditions and triggers defined in Water Sharing Plans (WSPs).
• Support environmental policy review based on the annual compliance assessments published by the department.

Strengths

• Data is modelled annually using the best available models, as stated in the description.
• Flows are simulated for several gauges in each river system, providing multiple points of analysis.
• Dataset is published under a specific license (CC-BY-NC-ND-4.0), clarifying usage rights.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
