Water Level Analysis

Water levels at Lock 3 - Overland Corner are well within positive historical averages. At 74.7% capacity, the facility is holding 51 GL of water. This volume provides a solid foundation for both urban and agricultural demands across South Australia.

Catchment & Hydrological Impact

Fed primarily by the River Murray, this reservoir plays a critical role in the Murray-Darling Basin drainage division. Managing the flow from the River Murray ensures that downstream agricultural zones receive consistent supply. The Murray-Darling Basin region relies heavily on the seasonal inflows captured here.

Agricultural & Economic Significance

Beyond standard municipal supply, Lock 3 - Overland Corner is a vital asset for the regional agricultural economy in South Australia. Irrigation allocations are directly tied to these storage metrics. Sustainable water management here ensures that both crops and livestock can survive prolonged dry spells.

Ecological & Recreational Context

The surrounding catchment of Lock 3 - Overland Corner 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. Authorities must constantly balance the need for human water consumption with the ecological necessity of maintaining healthy river systems downstream.

Current Weather & Evaporation Impact

With a mild reading of 15°C today, surface evaporation is significantly reduced, helping to preserve current volume. Currently experiencing partly cloudy conditions with no immediate precipitation, inflows remain entirely dependent on upstream river movement.

Future Outlook & Monitoring

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.
