This project will attempt to reduce significant erosion along an outer bank of the Brisbane River at Harlin through in-stream works to encourage base flows along an existing vegetated mid-stream channel. The proposed works involve the realignment of a large log to re-open the former channel and movement of in-stream material to ‘train’ base flows through a more stable channel and reinforce the current outer channel.

The proposed in-stream works will be carried out by an experienced local contractor and have been authorised by DERM under a Riparian Protection Permit. The site has been inspected and the design recommended by DERM technical officers and SEQ Catchments Soil Conservation Officer.

These works are an attempt to demonstrate a low cost river ‘training’ exercise to accelerate natural processes along an existing channel to a more stable form. The resultant form will reduce pressure on the outer bank from constant base flows and prevent further erosion and impacts on water quality and aquatic ecosystems.

This project will:

• minimise streambank erosion and improve water quality and aquatic health along the Brisbane River and downstream to Wivenhoe Dam, part of SEQ Hotspot Region
• realign a log and other in-stream material to re-open a stable mid-stream channel.
