Humpybong Creek is located adjacent to the CBD and foreshore precinct of Redcliffe. The creek flows from MacDonnell Road in the south and discharges into Moreton Bay north of Redcliffe Jetty.
Historically, Humpybong Creek was modified with the inclusion of staged weirs along the creek. These weirs produce sections of open water used for water supply. It is an important drainage corridor conveying untreated stormwater run-off from a catchment area of 180 hectares that contains urban residential areas, commercial properties, Redcliffe Harness Racing Club, Redcliffe Showgrounds, Redcliffe hospital and several parks.
The creek represents a highly modified waterway. The untreated stormwater inflows are contributing to declining quality of water throughout the creek system.
Humpybong Creek management plan
In 2014, a Management Plan and associated condition assessment was completed for Humpybong Creek. The condition assessment identified extremely poor water quality due to untreated stormwater inflows, deteriorating concrete edges, limited maintenance access, accumulated sediments and organic matter and aquatic weed infestations.
Rectification concept plan
A staged approach to the Humpybong Creek rectification works has been adopted to better manage the environmental impacts, financial and delivery constraints.
The rectification work for Stage 1 completed in 2021 included creation of a sediment basin, removal of deteriorating and unsafe concrete edges, improvements to maintenance access points, and removal of an island in the upstream section.
The Stage 2 works, to commence in June 2022, consists of improvements to a 100-metre section of drainage channel, downstream of the stage 1 weir, including removal of deteriorating and unsafe concrete edges, improvements to maintenance access points, weed removal, bank stabilisation and landscaping. The construction for Stage 2 is expected to be completed by August 2022 weather permitting.
The expected outcomes are:
- improved water quality and biodiversity
- improved pedestrian connectivity and safety
- landscaped parklands with improved visual amenity
- low maintenance self-sustaining green infrastructure
- improved water quality in Humpybong Creek.
- Improved environmental values.
