Track water storage, capacity and historical trends for major reservoirs in New South Wales, Victoria, Queensland and beyond.
Water levels at O'Shannassy remain exceptionally high. With current readings at 97.3%, the reservoir holds a robust 3 GL. This provides immense water security for the Victoria region.
The O'Shannassy River acts as the primary lifeblood for O'Shannassy, making it a cornerstone of the South East Coast (Victoria) network. Hydrological health in this specific drainage basin is vital for downstream ecosystems. The South East Coast (Victoria) region relies heavily on the seasonal inflows captured here.
Agriculture in the surrounding areas of Victoria depends heavily on the water security provided by O'Shannassy. Farmers and agribusinesses monitor these levels closely to plan their seasonal crop yields. Without the buffer provided by this massive 3 GL storage, regional farming would face extreme volatility.
The surrounding catchment of O'Shannassy 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.
Cooler current temperatures of 6°C help minimize evaporation losses across the reservoir. With raining conditions and 0.2mm of rain, the surrounding drainage basin is currently being naturally irrigated.
Looking ahead, the trajectory of O'Shannassy'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. Given the unpredictable nature of Australia's climate, from La Niña flooding to El Niño droughts, maintaining a dynamic operational strategy for O'Shannassy is absolutely essential.
