Seqwater issued an update on 5 January 2026 for Fernvale, Queensland, warning that heavy rain over the past three days has filled multiple dams and pushed river levels higher. Cedar Pocket, Wappa and Wyaralong dams are spilling automatically, and outflows from Maroon Dam have stepped up to maintain safe storage. Rising waters could make low-level crossings near Fernvale impassable within the next 48 hours, affecting drivers, riverside visitors and walkers on nearby trails.
According to Seqwater alerts, ungated dams like Cedar Pocket and Wyaralong spill as soon as they reach full capacity, leaving no way to slow the flow. Maroon Dam’s increased releases are a controlled measure by Seqwater’s flood operations but typically indicate that the wider South East Queensland system is under pressure. With soils in the Brisbane River catchment already saturated after days of coastal and inland rain, any further rainfall or upstream release will drive river heights up rapidly.
Twin Bridges, Savages Crossing and Fernvale Bridge are low-level crossings that could become inundated and impassable. Somerset Regional Council warns that these low-level crossings can turn into dangerous traps when water covers the road, cutting access along the Brisbane Valley Highway for commuters, delivery trucks, school buses and farm vehicles. Drivers and pedestrians should stay well away from any flooded section and follow local signage.
Residents should monitor Seqwater alerts and register for dam-release notifications on Seqwater’s website, making sure contact details are up to date to receive SMS or email advice. It also pays to check Bureau of Meteorology flood warnings and the Somerset Regional Council emergency page for road closures and safety advice. Setting up these alerts in advance can give families and businesses time to move vehicles and stock to higher ground.
Fernvale knows how fast the river can rise — after the devastating 2011 flood, and again in 2022 when torrential rains from a tropical low sent the Brisbane River over its banks and flooded several crossings. The Queensland Reconstruction Authority documents emergency works to rapidly reopen the Brisbane Valley Highway after the 2022 floods. Early warnings and community vigilance proved crucial during those events, and staying alert now remains the best way for Fernvale families and businesses to avoid being trapped by rising waters.
