Track water storage, capacity and historical trends for major reservoirs in New South Wales, Victoria, Queensland and beyond.
Water levels at Lake Glenmaggie are well within positive historical averages. With a current fill rate of 79.2%, the reservoir contains 178 GL. This indicates a very comfortable buffer for the upcoming dry seasons.
Fed primarily by the Macalister River, this reservoir plays a critical role in the South East Coast (Victoria) drainage division. Hydrological health in this specific drainage basin is vital for downstream ecosystems. The South East Coast (Victoria) region relies heavily on the seasonal inflows captured here.
Beyond standard municipal supply, Lake Glenmaggie is a vital asset for the regional agricultural economy in Victoria. The local economy, heavily rooted in agriculture, fluctuates in tandem with the health of this reservoir. Without the buffer provided by this massive 178 GL storage, regional farming would face extreme volatility.
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.
With a mild reading of 11°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.
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.
