Saturday 26 March.
We couldn’t quite complete the work to go back in on Friday. The last few days have been more of the same, Andrew working on the transducers for the sonar, grinding out a few patches on the keel and we’ve now finished antifouling. The anodes have been attached, the propspeed put on and steering fixed. Late Friday afternoon the Rivergate team put us in the slings on the crane ready for an early morning launch on Monday. Sue was a bit concerned when a thunderstorm came with high winds and heavy rainfall and we stayed swaying slightly in the slings.
So as we haven’t got much new to tell you we thought we’d share a few facts about the recent Brisbane river floods that have been reported on (some of them surprised us):
Local records for rainfall, flood levels and flood rescues were broken.
The “rain bomb” that broke over Brisbane on Friday, 25 Feb deposited 80% of the region’s ANNUAL rainfall within 3 days.
The downpour was greater than the 2010-2011 floods: about 50% more water poured into Brisbane River’s Wivenhoe Dam in half the time. The Brisbane river below Wivenhoe received 1,450 billion litres of water (equivalent to 3 x Sydney harbours).
The Brisbane “rain bomb” dropped more water on the city than typically falls in London over an entire year.
Two weeks after the river flooded, up to about 1100 tonnes of material was cleared from the river surface but they were also finding a lot on the bottom. 160 unknown objects from Hamilton Reach down t the port (about 18km). Sixty navigational aids, buoys and beacons were damaged and are currently being repaired and replaced.
Today we’ve been advised Brisbane river has been reopened to recreational boating during daylight hours only, everyone on board must wear a lifejacket as they continue to monitor unusual currents and debris. Crews last week had managed to clear 2000 tonnes of debris from the river. At one stage more than 150 objects needed to be dragged from the bottom of the river that were impeding shipping channels.
