Long-term Average Annual Extraction Limits for Border Rivers in NSW

NSW Border Rivers data contains modelled flow data for assessing compliance with long-term average annual extraction limits (LTAAEL). The dataset is produced by the NSW Department of Climate Change, Energy, the Environment and Water using models configured to represent water sharing plan rules. Outcomes are published annually on the department's website.

Use Cases

• Assess regulatory compliance by comparing modelled long-term average annual extractions (LTAAEs) against the LTAAEL.
• Model hydrological flows under water sharing plan (WSP) operation and development conditions.
• Compare scenario outcomes by using flows from this dataset alongside outputs from other models like the annual permitted take (APT) model.

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 measurement points.

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.
