Fish migration barriers at Enoggera Creek culvert

The Bennett Road culvert crossing of Enoggera Creek in Brisbane represents a barrier to upstream fish migration due to high velocity, shallow flow, water surface drop, and lack of resting place for fish. This structure represents a barrier to aquatic fauna connectivity between habitat areas in the creek and prevents migration from downstream to upstream reaches for more than 6 species of native freshwater fish. The Walaman prefabricated fishway system has recently been installed to provide for upstream fish passage and to overcome the fish migration barriers for a range of flow conditions at the culvert.
