Scrubby Creek recovery
With over 60 kilometres of waterways, Scrubby Creek is the second largest catchment in the City of Logan. Spanning from Greenbank in the west to Meadowbrook in the east, Scrubby creek flows into Slacks Creek, which then flows to the Logan River.

Did you know that many of our native fish try to migrate to the estuary to spawn? Juvenile fish born in the estuary migrate up the waterway to freshwaters to live their lives as adults. Barriers like the pedestrian culvert causeway over Scrubby Creek (near the intersection of Queens Road and Loganlea Road) prevented native fish movement and would have caused a decrease in fish numbers over time.
The Queens Road Fish Passage project replaced the partly collapsed and inappropriately sized culverts with a new pedestrian footbridge and instream rock ramp fishway. This allows fish to swim further along Scrubby Creek and help them reach the estuary.
If you visit the creek, you will see a series of rock ridges next to the new footbridge. This is called a rock ramp fishway. The ridges are designed to slow the water and provide deep resting pools for fish as they move through the fishway. The change in water level from one ridge to the next is designed to allow native fish to pass through. This structure also stops erosion while still allowing fish to pass.
Poorly connected waterways also allow pest fish such as tilapia, carp and mosquito fish to flourish. Fixing barriers that prevent movement along waterways, will give our native fish, like the Australian bass, a fighting chance.

This project was supported by Healthy Land and Water, through funding from:
- The Australian Government’s National Landcare Program
- Logan City Council’s Environment Levy
- OzFish Unlimited.
It was also co-funded under the Queensland Recreational Fishing Grant (QLD Department of Agriculture and Fisheries).
