Short answer: As of 17 September 2019, WaterNSW reported critically low dam storage levels across NSW, with most major catchments well below historical averages due to prolonged drought. Inflows remained minimal, and water restrictions were in place across many regional centres. The report highlighted the urgent need for improved water harvesting and storage solutions on farm properties.

📋 Quick Answer
Australia faces recurring drought cycles, with inland NSW, QLD, and SA most severely affected. Farm dams are the most effective on-property drought response — providing water security independent of town supply or rainfall. Size your dam for 2–3 years of total water demand, build at maximum depth to minimise evaporation, and maintain at least 50% storage capacity heading into summer.
