Ironstone Gully - Ironstone Gully Falls
Basin : Busselton Coast
Catchment : Capel River
The condition of the Ironstone Gully Falls (site code: CAPE-02/6100197), was assessed between 26 and 27 October 2009, over a 100-m length of stream. At this time no previous assessments of river ecology had been reported.
The site is a a tributary of the Capel River and flows over an iron-rich red rock formation before dropping over a ledge.
The assessment was conducted using standard methods from the South West Index of River Condition. Measures chosen for this assessment included fish and crayfish, macroinvertebrates, aquatic habitat, water quality (dissolved oxygen and temperature logged over 24h, and electrical conductivity, pH, colour, alkalinity, turbidity and nutrients), fringing vegetation, channel morphology, erosion, connectivity, local land use and flow.
Condition summary
The site was assessed as part of a national assessment of river condition – view report here.

Fish and crayfish
One crayfish species was found at this site in October 2009:
- Cherax quinquecarinatus (Gilgie)
Fish may be present at this site; however, limited opportunities for effective sampling mean their presence has not yet been confirmed. Additionally, as a small tributary, the watercourse may not support permanent fish populations. As such, the absence of detections does not necessarily indicate the absence of fish.
