Low-level floodwater releases from Wivenhoe Dam have led to the closure of Colleges Crossing in Ipswich, as Seqwater manages rising water levels following significant rainfall in the region.
Heavy rainfall over the past week has seen significant inflows into Wivenhoe Dam, with some areas in the Upper Brisbane catchment recording over 50mm of rain in an hour. In response, Seqwater initiated low-level floodwater releases on 2 January 2025 to manage dam storage capacity and mitigate downstream flooding risks.
Historically, Colleges Crossing—a key low-level bridge over the Brisbane River—has been prone to closures during dam releases and heavy rainfall events. Previous closures, including during the 2011 and 2022 floods, caused significant disruptions to local travel and recreation.
Current Closures and Impacts
Flood releases from Wivenhoe Dam will continue for approximately 24 hours, Seqwater confirms. As of 3 January 2025, 11:12 am, Colleges Crossing is officially closed to all traffic due to rising water levels and flooding risk. All lanes are blocked and motorists are advides to opt for alternative routes.
Meanwhile, Twin Bridges and Savages Crossing remain closed. Authorities have advised motorists and residents to avoid unnecessary travel through these areas and avoid unnecessary travel in affected regions.
Seqwater reports that Wivenhoe Dam is operating within its flood storage compartment, currently at 90% capacity, with controlled releases continuing to create space for additional inflows.
Weather Threats for Ipswich and Brisbane
According to the Bureau of Meteorology as of 3 January, Ipswich is currently facing isolated to scattered storms, bringing heavy rainfall and an increased risk of local flash flooding. The Brisbane River catchment area, including Ipswich, remains vulnerable to rising water levels from both rainfall and ongoing dam releases.
Although the weekend’s weather may progressively get better, meteorologists have cautioned that rising water levels are expected to remain and any more rain could aggravate low-lying area flooding risks.
To guarantee safety during this period of increased flood risk, Ipswich residents are advised to track official weather updates from the Bureau of Meteorology, avoid flooded roads and crossings, and arrange other travel paths.
Impact on Ipswich Community and Recreation
Colleges Crossing is a well-known recreational spot for Ipswich locals, popular for picnics, kayaking, and fishing. With its closure, both residents and local businesses reliant on weekend visitors will experience disruptions.
Safety remains the priority. Seqwater has urged residents to stay informed via official channels and avoid entering floodwaters, as conditions can change rapidly.
Flood releases will be monitored closely over the next 24 hours, with updates provided by Seqwater and local authorities. Motorists and residents are encouraged to stay updated and adhere to road closure signs.
For now, residents are advised to plan alternative routes and remain vigilant around rising water levels in and around Ipswich.
