Part 5 Activities
Tarlo River National Park Flume Replacement
Upper Lachlan Shire
The project (Tarlo River National Park Flume Replacement) involves replacing a structurally
failed concrete flume, worsened by dispersive soils due to recent drought and flood events.
The proposed solution is to install a new rock flume, specifically designed to be compatible
with the local shrink/swell soil conditions.
Additionally, the project includes expanding the current flume's footprint to accommodate the
larger structure and upgrading a 4 km section of Long Swamp Road to improve construction
access and facilitate the transportation of equipment.
Excess material from the construction will be utilised on site and on Long Swamp Road. The
track upgrade will begin at the junction of Potters Trail and end at the junction of Bush
Bottoms Trail.
The project has a backup plan to use a decommissioned quarry on Towrang Road for the
disposal of spoil material if it cannot be utilised on site.
