Annual Permitted Water Take for the Lachlan River Basin, 2019–Present

Annual permitted take (APT) data for the Lachlan region, a critical mechanism for enforcing sustainable diversion limits under the Murray-Darling Basin Plan. The dataset, sourced from the NSW Department of Climate Change, Energy, the Environment and Water, models water availability against climatic conditions to calculate permitted consumptive use. APT has been enforced since July 2019, with compliance tracked from the 2019–20 water year.

Use Cases

• Track compliance with sustainable diversion limits based on the annual permitted take calculation method.
• Model water availability for consumptive use based on irrigated crop area and planting decisions.
• Analyze water entitlement holder distribution and usage patterns mentioned in the description.
• Assess environmental water allocations based on storage operation models for consumption and the environment.

Strengths

• Enforcement date is explicitly stated as July 2019.
• Data supports tracking of cumulative SDL compliance from the 2019–20 water year.
• Model configuration includes specific estimates like irrigated crop area and storage operations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data freshness should be verified despite a last updated date of 2026-05-13.
