This project addresses the objectives of the Oaky Creek Catchment Restoration Project, working with the community within a defined focal area to deliver on-ground works to improve water quality in local waterways and Moreton Bay.

The landholder on this property has made an expression of interest to undertake remedial works on their property. Since taking over this property the landholder has improved the grazing land management practice in order to reduce erosion and impacts of stock. It is recommended that immediate works are to be carried out on two retreating gullies that are losing significant amounts of sediment during each rain event.

Rehabilitation of this area will consist of two sites to reduce sediment loads.

Site 1
Engineering works will consist of a dam constructed to reduce overland flow entering into the affected gully. Water will be redirected and discharged into a stable drainage line which will be fenced off by the landholder to create a new paddock. Cattle will be allowed access to this paddock periodically to improve stabilisation and allow for improved pasture to establish. Two small stock watering points will be constructed in the drainage line to reduce velocity of water and prevent head cuts.

Site 2
Significant overland flows running into a steep embankment have caused an eroding gully 10m deep. A number of diversion banks will be constructed to redirect the water across the paddock and render in a stable drainage line along the road. Gullies are to be fenced off and rehabilitated with pasture.

This project will be enhanced by similar works across the catchment on neighbouring properties aimed at improving water quality and reducing sediment loss within the catchment.  

Diversion banks will be constructed at Site 1 to redirect overland flow into a stable drainage line, which will be fenced off by the landholder to create a new paddock. At Site 2 additional diversion banks will be constructed to redirect the water across the paddock and render in a stable drainage line along the road.

Gullies are to be fenced off and rehabilitated with pasture.

Two small stock watering points will be constructed in the drainage line to reduce velocity of water and prevent head-cuts.

This project will:

• improve water quality in Oaky Creek and the Logan River
• address the interrelated water and land management issues that are contributing to nutrients and sediment entering waterways.

Construction of a dam will reduce overland flow entering into the affected gully.
