Annual Permitted Water Take Modelling Data for the Gwydir Region

Annual permitted take (APT) data is a regulatory mechanism for sustainable water management in Australia's Murray-Darling Basin. The dataset contains modelled APT values for the Gwydir region, calculated based on water availability, climatic conditions, and infrastructure estimates from the NSW Department of Climate Change, Energy, the Environment and Water. APT enforcement began in July 2019 and is used to track compliance with long-term sustainable diversion limits.

Use Cases

• Track compliance with sustainable diversion limits based on the APT calculation method described.
• Model water allocation scenarios based on estimates of irrigated crop area and planting decisions.
• Analyze water entitlement holder usage patterns based on the distribution and use patterns mentioned.
• Assess the impact of storage operations on water supply for consumption and the environment.

Strengths

• Enforced since July 2019, providing a regulatory compliance baseline.
• Based on a defined reference period (1895–2009) for calculating sustainable diversion limits.
• Includes estimates of river management, infrastructure, and agricultural practices.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to the water resource plan period.
