Collected by: Dunedoo Area Community Group Inc (Dunedoo Coolah Landcare)

Group assisted with a National Parks Association flora/fauna survey and has had interest since. Informal fish surveys continue with only carp and gambusia present to date.

 

Water quality:

Turbidity: 10
pH: 8
Salinity: 820µS

While taking samples saw a father emu with two small chicks, very cute.

ACT Waterwatch says:

The water quality isn't too bad here. Salinity is still high but not at all as high as other places in the Castlereagh. Deep rooted native trees can be useful tools for managing salinity, and that may be happening here.

About the site

Large wide open sand based river, good tree cover on banks consisting of red gum and river oak, flat sand bed with water course snaking through the sand, consists of pools at time of sampling however sub-surface flow is probable. Phragmites and cumbungi growing in stream, good cover of slender bamboo grass on banks, some good snags.

What's going on:

No stock access directly to site and very little human disturbance, prominent evidence of feral pigs and pigs have been sighted in the past, gambusia and carp both highly visible, some pools are crystal clear while others are covered in a mat of algae.

Only survey work has been conducted.
