Long-term Average Annual Extraction Limits for NSW River Systems

Modelled flow data for gauges in New South Wales river systems, used to assess compliance with sustainable water extraction limits. The dataset is produced annually by the NSW Department of Climate Change, Energy, the Environment and Water using extended hydrological models. Outcomes are published on the DPE website, with the record last updated in May 2026.

Use Cases

• Assess regulatory compliance by comparing modelled long-term average annual extractions against extraction limits.
• Analyze hydrological impacts of water management rules by comparing flows from different scenario models.
• Monitor sustainable water use trends in NSW river systems based on simulated gauge data.

Strengths

• Data is modelled annually using the best available models configured to represent water sharing plan rules.
• Flows are simulated for several gauges in each river system, providing spatial coverage.

Limitations

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