One of the two problem areas on Station Creek that will be remediated.
Project will tackle two highly-active Station Creek erosion sites
LDC is soon to undertake another large-scale restoration project on Havilah Station, near Collinsville. Remediation efforts are expected to stop 15,262 t/y sediment from entering local waterways, and an estimated fine sediment supply at the coast of 9,920t/y.
The Station Creek remediation site consists of two highly-active sections of eroding streambank (1,050m and 554m), that run into the Bowen River. The sites are 2km upstream of the Bowen Developmental Road crossing.
Works will consist of bank battering the vertical banks to a stable grade, installation of a timber pile field, rock chute batter drains and bunds to manage the entry of overland flows through multiple existing gullies.
About 1,980 timber piles will be used to abate sediment, they will be sourced from local contractors, and acquired from state forests.
Following mechanical works, the sites will be revegetated with hydromulch to achieve groundcover, and planting, irrigation, and maintenance of tube stock to restore riparian vegetation.
Stock exclusion fencing and grazing management will ensure project success in the long term.
This will be the third large-scale restoration project carried out by NQ Dry Tropics and the Havilah Station landholders.
Engineering firm Neilly Group has been contracted to design the on ground works. Local contractors will carry out the work.
Benefits of streambank stabilisation include reducing loss of land, maintaining the flow or storage capacity of the waterway and reducing the downstream effects of sediment resulting from bank erosion.
A cultural heritage survey and impact assessment was completed in consultation with the Birriah People in February.
Construction began this month (June).
