Track water storage, capacity and historical trends for major reservoirs in New South Wales, Victoria, Queensland and beyond.
The storage situation at Cataract remains highly stable. At 90.9% capacity, the facility is holding 97 GL of water. The local water grid benefits significantly from this stable storage level.
Fed primarily by the Cataract River, this reservoir plays a critical role in the South East Coast (NSW) drainage division. 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.
Beyond standard municipal supply, Cataract is a vital asset for the regional agricultural economy in New South Wales. Farmers and agribusinesses monitor these levels closely to plan their seasonal crop yields. Without the buffer provided by this massive 97 GL storage, regional farming would face extreme volatility.
The surrounding catchment of Cataract also supports diverse local flora and fauna. When capacity allows, Cataract becomes a hub for regional tourism and water sports. However, environmental flow releases must be carefully balanced to protect downstream river health.
Cooler current temperatures of 14°C help minimize evaporation losses across the reservoir. Currently experiencing partly cloudy conditions with no immediate precipitation, inflows remain entirely dependent on upstream river movement.
Looking ahead, the trajectory of Cataract's water levels will depend heavily on upcoming seasonal rainfall patterns. 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 Cataract is absolutely essential.
