Modelled Daily River Flow Rates for the Lachlan Valley, NSW

Time series of modelled daily flow rates in megalitres per day across river systems in the Lachlan Valley, New South Wales. Data is produced by the NSW Department of Climate Change, Energy, the Environment and Water using the best available hydrologic models at the time of publishing. The modelled historic climate period typically spans from the early to mid-1890s to the water year prior to the publication date.

Use Cases

• Analyze long-term river flow trends based on modelled historic climate data.
• Assess water availability for agricultural or environmental planning based on daily flow rates.
• Calibrate or validate other hydrological models using the published model outputs.
• Study the impact of climate variability on river systems in the Lachlan Valley.

Strengths

• Covers a long historic period, typically from the early to mid-1890s onward.
• Modelled data provides a consistent, system-wide view of river flows.
• Expected to be updated annually, as per the description.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is modelled, not directly measured, which may introduce uncertainties.
