The morning after ....

This will actually include some material from the afternoon after, but I can't recall "the night before" leading to ill effects lasting past noon.

This begins with our morning walk to and along Lakeside Drive.  No water over road!  Just an AGSC guy blowing the crud off the road.
There is enough sand on the shared path to indicate some attention being needed when riding.
The jetty has reappeared.
So has the lagoon boardwalk but it is very slippery.  Another EGSC guy was washing that down with a sprayer but it is going to take him a long while to finish.  I tested it later and it would be lethal to try to ride a bike across it.

The entrance is visible.
This sign is a boat speed limit that has been floating in the water and now resides on the side of the road.  I don't think it would be good if it met an outboard propeller!
I later rode to check the gauge.  Plenty of Little Black Cormorants on the jetties
... and pelicans near the wharf.
Although ripples made precise measuring of the depth impossible I took 0.6 m as a good estimate.
Here os my chart comparing the depth of the Inlet with local rain.  The correlation has been quite good until this event where we got relatively little rain.

However, looking at rain measured at the Bombala AWS shows the picture well.  Note the different scales!
A Mallacoota local mentioned the flood in July 2005.  I don't have depth stats for 2005 but the similarity of pattern for the rainfall at Bombala is very evident.


We also went to check the outflow.  At the Bastion steps there was a lonely remnant of the sand road!
I counted 42 Pelicans in this flock and there were a similar number in the mouth of Harrisons Channel.
I was initially very excited by these raptors (4 in total).  These seemed very rufous through binoculars,  However looking at the photo meant that they were all Whistling Kites.
Whoever said the outflow wasn't wide enough was a goose.  It is carving itself a very nice channel, cutting towards the Point rather than Gabo.  Definitely enough flow for a slalom course (with an associated CPR contest once the bodies were recovered). 
Water has been here!
Very little washed up marine life anywhere on the beach.  This sponge was an exception
