Catchment Update:
Only 1-2mm of rain was received across Ipswich City's catchments overnight, though the continued runoff from earlier rains during yesterday led to expected small rises in most streams, all below minor flood level.
All streams are currently continuing to fall, with exception to the Bremer still rising at One Mile as waters from the Warrill and upper Bremer continue to through the stream.
Wivenhoe Update
At 6am Saturday, Wivenhoe Dam was 68.45 m AHD and rising steadily with all five gates open and releasing about 890 m3/s.
River levels upstream of Wivenhoe Dam are rising again, generating further inflow to the dam It is intended to ramp up the release from Wivenhoe to 1,200m3/s by midday Saturday 08/01/2011.
Further assessments will be undertaken to determine increases above this level.
However, given the high likelihood of significant inflows in the next week, this may be increased.
Infrastructure Update:
All roads are now open, with the exception of Colleges Crossing and Kholo Bridge (closed at 7:45am today).
The projected Wivenhoe release of 1,200m3/s combined with Lockyer flows and local runoff will mean that all crossings downstream of Wivenhoe (Twin Bridges, Savages Crossing, Burtons Bridge, Kholo Bridge and Colleges Crossing) will be adversely impacted for several days.
At this stage, Fernvale and Mt Crosby Weir Bridge are not expected to be affected but they could potentially be affected if the predicted rainfall totals eventuate.
