Track water storage, capacity and historical trends for major reservoirs in New South Wales, Victoria, Queensland and beyond.
Lake Rowallan is experiencing significant storage depletion. With the reservoir sitting at just 35.7%, the total available volume is 131 GL. This lower-than-average capacity may trigger preliminary water-saving advisories in Tasmania if dry conditions persist.
Fed primarily by the Mersey Forth, this reservoir plays a critical role in the Tasmania drainage division. Hydrological health in this specific drainage basin is vital for downstream ecosystems. Catchment dynamics in the Tasmania are deeply influenced by the retention capacity of Lake Rowallan.
Beyond standard municipal supply, Lake Rowallan is a vital asset for the regional agricultural economy in Tasmania. Irrigation allocations are directly tied to these storage metrics. Sustainable water management here ensures that both crops and livestock can survive prolonged dry spells.
The surrounding catchment of Lake Rowallan 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 9°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 Lake Rowallan'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 Lake Rowallan is absolutely essential.
