Regarding your query on the Narran Lakes, here is an update and good
news on the breeding event, from Peter Terrill (DECC)...

Subject: Narran Lakes Bird Breeding
Just to let you know that DECC's Parks and Wildlife staff have reported
a significant bird breeding event in the Narran Lakes Nature Reserve.
This is in response to about 25 GL of inflow since December rainfall
which has filled Clear Lake, Back Lake and Long Arm.
A survey by boat yesterday through the lignum between Clear and Back
Lake come up with some preliminary estimate of numbers. An aerial
survey next week will provide more accurate estimates. However, this is
shaping up to be the most significant waterbird breeding event in the
MDB in the last 8 years.
The preliminary numbers provide by Parks and Wildlife ecologist, Duncan
5000-6000 pairs of Strawnecked ibis on eggs (average 2 per nest)
1500 pairs of White ibis also on eggs
100-200 pairs of Royal spoonbills also on eggs, and
~50 pairs of Glossy ibis on eggs
Although flows have dropped to cease to flow levels in the Narran in
QLD, there are good prospects of significant inflows to Beardmore dam
from rain in the Maranoa catchment. Releases from Beardmore should
re-establish flows at Hastings (Balonne Minor upstream of Narran River
nr Dirranbandi) next week and local rain in the Lightning Ridge area may
generate runoff to re-establish and maintain flows into the Lakes until
flows out of QLD catch up.
I will provide an update of flows in the near future. In the meantime
the attached graph may be of interest.
Note that I have fired an email off to the Narran Lakes Ecosystem
Project team but at this stage am not aware of any planned research
As this is a significant event which is likely to generate media and
political interest please provide a "heads up" to those who need to know
within your jurisdictions.
