Track water storage, capacity and historical trends for major reservoirs in New South Wales, Victoria, Queensland and beyond.
Water capacity at Grahamstown Lake is holding at moderate levels. The current reading shows the reservoir at 58.1%, translating to 192 GL. This represents a typical midpoint for the region's hydrological cycle.
The Nine Mile Creek & Seven Mile Creek acts as the primary lifeblood for Grahamstown Lake, making it a cornerstone of the South East Coast (NSW) network. Hydrological health in this specific drainage basin is vital for downstream ecosystems. The South East Coast (NSW) region relies heavily on the seasonal inflows captured here.
Agriculture in the surrounding areas of New South Wales depends heavily on the water security provided by Grahamstown Lake. The local economy, heavily rooted in agriculture, fluctuates in tandem with the health of this reservoir. Without the buffer provided by this massive 192 GL storage, regional farming would face extreme volatility.
The surrounding catchment of Grahamstown Lake 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.
Current local temperatures are sitting at a moderate 17°C. With 0mm of recent rainfall and clear sky 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. State water authorities utilize highly sophisticated monitoring tools to ensure every drop is accounted for. Resilience against extreme weather events remains the ultimate goal for the managers of this critical infrastructure.
