Track water storage, capacity and historical trends for major reservoirs in New South Wales, Victoria, Queensland and beyond.
Water levels at Hay Weir are well within positive historical averages. With a current fill rate of 84.5%, the reservoir contains 13 GL. This volume provides a solid foundation for both urban and agricultural demands across New South Wales.
Beyond standard municipal supply, Hay Weir 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 13 GL storage, regional farming would face extreme volatility.
The surrounding catchment of Hay Weir also supports diverse local flora and fauna. When capacity allows, Hay Weir 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 15°C help minimize evaporation losses across the reservoir. With 0mm of recent rainfall and partly cloudy skies, the catchment is relatively dry today.
Looking ahead, the trajectory of Hay Weir's water levels will depend heavily on upcoming seasonal rainfall patterns. 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.
