Analysis and insights of our water data

We analyse water related data to produce insights and information about water management. The department then uses the information and insights to manage water more effectively.

Data dashboards

Allocations dashboard

Data visualisation tool to view and analyse water availability announcements.

Usage dashboard

Historical water usage across different regions within NSW, presented by water source, licence category and river section.

Held environmental water dashboard

A summary of held environmental water shares, usage and trade data.

Environmental water summary report

Generate water source and water sharing plan report for environmental water entitlements.

Environmental water trades register

Search environmental held water trades between licences.

Utilisation dashboard

Historical water utilisation and activation rates by water source.

Share component dashboard

Share component since the commencement of the water sharing plan by water source and licence category.

Local water utility performance

Regional local water utilities can use the online performance monitoring database to annually report water supply and sewerage data, and

Tracking groundwater extraction against extraction limits

Find out more about how extractions are tracking against extraction limits in inland groundwater sources.

Accounting rules summary

Water accounting rules by licence category for each regulated water source.

Catchment based annual analysis

We produce annual reports for each catchment that provide insights into:

  • Climatic conditions (How did the annual reporting period compare to historical conditions?)
  • Water resources (How much water was there?)
  • Water resource changes (Where did the water originate and where did it go?)
  • Water resource commitments (How was the water distributed amongst stakeholders?)
  • Water resource use (How much entitlement is active and what proportion of available water is being used?)
  • Environmental water (How much water was available for environmental use, and how much was delivered to environmental assets?)
  • Water resource management (What legislative rules determined the sharing of available water?)
  • Water market activity (How much water is being traded, and how much does the water cost?)
