Long-term Average Annual Extraction Limits for NSW River Systems

NSW Department of Climate Change, Energy, the Environment and Water provides modelled flow data for assessing compliance with Long-term Average Annual Extraction Limits (LTAAEL). The data contains simulated flows at several gauges in each river system, generated annually using the LTAAEL model configured to represent water sharing plan rules. Outcomes are published on the DPE website.

Use Cases

• Assess regulatory compliance by comparing modelled long-term average annual extractions against the LTAAEL.
• Analyze the impact of water sharing plan rules on river system flows based on simulated gauge data.
• Compare water availability scenarios by contrasting flows from the LTAAEL model with outputs from other models like the Annual Permitted Take or Without Development models.

Strengths

• Data is modelled annually using the best available models, as stated in the description.
• Flows are simulated at several gauges per river system, providing multiple points of analysis.
• Model is configured to represent specific water sharing plan development and management rules.

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.
