Water Level Analysis

Tombullen is currently maintaining very healthy storage levels. At 90.4% capacity, the facility is holding 11 GL of water. This volume provides a solid foundation for both urban and agricultural demands across New South Wales.

Agricultural & Economic Significance

Beyond standard municipal supply, Tombullen is a vital asset for the regional agricultural economy in New South Wales. The local economy, heavily rooted in agriculture, fluctuates in tandem with the health of this reservoir. Sustainable water management here ensures that both crops and livestock can survive prolonged dry spells.

Ecological & Recreational Context

Ecologically, the reservoir and its immediate wetlands serve as a crucial habitat for native Australian wildlife. During periods of healthy water levels, the area often sees an increase in recreational activities such as fishing, boating, and camping. However, environmental flow releases must be carefully balanced to protect downstream river health.

Current Weather & Evaporation Impact

With a mild reading of 15°C today, surface evaporation is significantly reduced, helping to preserve current volume. With 0mm of recent rainfall and partly cloudy skies, the catchment is relatively dry today.

Future Outlook & Monitoring

The Bureau of Meteorology's climate outlooks will play a pivotal role in predicting the future inflows for this catchment. Continuous telemetry and advanced hydrological modeling are employed to forecast storage changes. Resilience against extreme weather events remains the ultimate goal for the managers of this critical infrastructure.
