needed to maintain a catchment’s natural character and
ecosystem health however, as this measurement is an ‘average’, flows do naturally fall below MALF during
prolonged periods of dry weather or drought.
Estimations of MALF are made using long term flow records but, if no records are available, it can also be
estimated using records from hydrologically similar streams. When developing estimates of MALF, flow
records are first ‘naturalised’. Primarily this involves removing the
well-maintained with approximately ten small stockpiles of sawdust waiting to be spread. The area was
intact, with no cracking or slumping evident on either the fill area or the tip face. No unauthorised material
was noted. There was no ponding observed, despite heavy rain the previous day, and the material was damp
underfoot. The pre-fill gully was well grassed with no sign of exposed soil or sediment runoff. The stage 1 fill
area was damp underfoot and had been recently grazed, and showed no sign of
minor amount of erosion at one point that was likely to have been caused by the heavy
rain in the previous week.
The stormwater ponds were all nearly full, with approximately 0.3-0.5 m of freeboard.
The contents were a relatively clear brown colour, and the lowest pond had an iron
oxide sheen present on the surface. The downstream stormwater drain had recently
been cleared of vegetation and there were no obstructions to flow. Silt controls were in
place, and appeared to be effective as the
tidy.

The site was unmanned at the time of inspection. There was processing equipment
onsite. The hill that had been pushed into the quarry pit for reinstatement had been
graded and contoured. There was no dust found beyond the boundary of the property.
There was no runoff from the site occurring at the time of inspection. The site was tidy.

The site was unmanned at the time of inspection. It was raining and windy at the time
of inspection. The reinstated

time of the inspection with 5 mm of rain over the past three days.
Significant earthworks were being undertaken at the site. The contractor on-site
outlined that the whole area was being prepared for eventual filling. Pipe had been laid
down the length of both channels to pipe the spring water. Stormwater pipes and risers
had also been installed to intercept stormwater from the surrounding pasture. At the
time of the inspection, the contractor was digging a retention/silt pond for
this area.
The truck wash area looked to be working well. The settling ponds at the truck wash
area were full with a small clear discharge to the drain. There was some evidence of
fines in the drain due to recent rain and the pump having broken down which was
being repaired. The slurry area at the back of the yard was full which would need to
be emptied soon. The main drain through the yard had been cleaned out. Overall the
site looked to be well maintained and managed at the time of

The weather was overcast and misty, with a light W wind, after rain the previous
day. The storm ponds, which had not been emptied for over six weeks and were
soupy green, were released all together at slow rate to reduce discoloration of

Other Management Issues
Weeds - Medium There are many weeds impinging on the values of this site
including climbing asparagus, wandering willy, wild ginger,
Japanese honeysuckle, African clubmoss, brush wattle and wild
cherry.
Predators - Medium Predators such as rats, mustelids, possums, hedgehogs and feral
cats will be having an impact on the site.
