On-ground efforts in Williams (Williams River) and Pumphreys Bridge (Hotham River) in February and March this year resulted in nearly a kilometre of river reach being treated with various rehabilitation techniques.

Project partners Wilman (Dryandra) People Corporation provided a cultural induction at each site, before works began. The Hotham River is particularly significant, due to the Pumphreys Bridge area being part of a Dreaming track, and holding a significant place in Noongar history and culture. The Wilman Corporation also provided two heritage monitors, and two hard workers for much needed and appreciated on-ground support.

Rehabilitation techniques on the banks included:

  • Gentle re-sloping, where there were steep slopes and no existing vegetation.
  • Pinning jute mat (biodegradable plant material to protect the bank, suppress weeds and provide a medium for planting later in the year).
  • Placing logs and woody debris for bank stabilisation and Rakali habitat (Australian Water Rat).
  • Protecting trees that were vulnerable to erosion on the banks, once more with placement of rocks and logs.
  • Constructing small in-stream structures with rock and/or logs to enhance pools, restore river function, and improve habitat conditions.

This river reach at Pumphreys Bridge is not accessible, due to being bound by private land, however similar works were carried out in 2024, and can be seen at the public camping grounds where the Hotham River crosses the Narrogin-Wandering Road

On the Williams River, works were focused downstream of the town weir next to the Lions Rest Area. If you’re passing through, take a look by following the dirt track at the far end of the car park, and pop down to the river where you will see access points. There are several structures along that stretch, ranging from re-sloping and using primarily rocks to reinforce the banks, and use of logs to enhance habitat and compliment the rock material. There are also a couple of in-stream structures that aim to help maintain and build up the pools, which are becoming more and more important in the drying climate. The biodegradable jute mat placed on all the re-sloped banks will provide good spots for planting seedlings later in the year.

This project is in partnership with the Wilman (Dryandra) People Corporation and funded through partnerships with both South32 Worsley Alumina and Newmont Australia (Boddington) with support from the Shire of Wandering.
