Track water storage, capacity and historical trends for major reservoirs in New South Wales, Victoria, Queensland and beyond.
Lake St Clair is currently facing severe depletion. Currently at only 0.7% of its 2,000 GL capacity, the situation requires urgent monitoring. This critical shortage heavily impacts regional water security across Tasmania.
The Derwent River acts as the primary lifeblood for Lake St Clair, making it a cornerstone of the Tasmania network. Managing the flow from the Derwent River ensures that downstream agricultural zones receive consistent supply. The Tasmania region relies heavily on the seasonal inflows captured here.
Agriculture in the surrounding areas of Tasmania depends heavily on the water security provided by Lake St Clair. 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.
The surrounding catchment of Lake St Clair also supports diverse local flora and fauna. 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 7°C today, surface evaporation is significantly reduced, helping to preserve current volume. The recorded precipitation of 0.2mm indicates active rainfall in the catchment, which is excellent news for inflows.
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. Given the unpredictable nature of Australia's climate, from La Niña flooding to El Niño droughts, maintaining a dynamic operational strategy for Lake St Clair is absolutely essential.
