Track water storage, capacity and historical trends for major reservoirs in New South Wales, Victoria, Queensland and beyond.
South Dandalup is currently facing severe depletion. Sitting at a mere 15.9% of its 138 GL total capacity, extreme conservation measures may be required. This critical shortage heavily impacts regional water security across Western Australia.
Fed primarily by the South Dandalup River, this reservoir plays a critical role in the South West Coast drainage division. Managing the flow from the South Dandalup River ensures that downstream agricultural zones receive consistent supply. The South West Coast region relies heavily on the seasonal inflows captured here.
Agriculture in the surrounding areas of Western Australia depends heavily on the water security provided by South Dandalup. Irrigation allocations are directly tied to these storage metrics. Without the buffer provided by this massive 138 GL storage, regional farming would face extreme volatility.
Ecologically, the reservoir and its immediate wetlands serve as a crucial habitat for native Australian wildlife. When capacity allows, South Dandalup 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 8°C help minimize evaporation losses across the reservoir. Currently experiencing clear sky conditions with no immediate precipitation, inflows remain entirely dependent on upstream river movement.
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. Given the unpredictable nature of Australia's climate, from La Niña flooding to El Niño droughts, maintaining a dynamic operational strategy for South Dandalup is absolutely essential.
