Great work everyone.  Interesting to see that January's freshwater lens (on the back of heavy Jan rainfall) has dissappeared with extremely dry Feb conditions.

Oxygen levels at 0.5 metres double checked and values as noted.  JObst - no worreis, quite a plausible DO value, most likely due to a mid-water algal bloom producing excess DO.  Thanks for noting this & double checking - great QAQC!!

Great results everyone, thanks for your efforts!

Possibly one of the most consistent WQ profiles I've seen through the entire system for some time, hence confirming the flushing/resetting of water quality profile from an extended and high magnitude flood event!  It will be very interesting to see what the summer months bring & how long it takes turbidity to settle down.  Cheers Jarred.

The multi-parameter meter was found turned off just prior to taking obs at this site (last of 4) - I turned back on and continued without re-calibrating. 

(I started with a full set of calibrations completed)

 

No worries Brad, thanks for flagging this, but happy to report this shouldn't be an issue.  The YSI is a very stable unit and turning on/off between sites isn't an issue - and most importantly results look spot on.  Very different profile compared to the lower estuary - very fresh, turbid and well mixed!  Great work getting out today, partiuclarly given the weather...  Cheers Jarred

Great data set again - with some really interesting low DO's in the bottom stratified level.  This is similar to what we found prior to the last artificial opening and i think this represents some 'old' seawater which has been in residence for some time now.  This doesn't pose any risk due to a highly oxygenated profile downstream, but a good example of where winter flushing is required to reset the system!  Thanks Jarred.

Hi everyone, great testing once again, sincere thanks.  We've had a pretty wild couple of months on the swell front and the data shows a distinct salt-wedge as a result!  Interesting times with the mouth too, varying from an open to closed state with the ocean, but looks like it may now stay open into our winter flow season.  Thanks

Great work on the monthly testing everyone.  System looks well mixed with good WQ conditions throughout the estuary following the recent ARMO.  Flow rates are interesting/challenging at present - enough to consistently raise the water level - but not enough to maintain an open tidal system...  Looks as though we may need to perform another artificial opening in the coming weeks t once again alleviate short-term impacts of flooding, as long as Safe, Appropriate & Effective conditions exist.  Thanks Jarred.
