Notes

Thanks everyone!  Results remain really interesting and fantastic photopoints capturing the current mouth condition.  Interestingly, there's been enough flow to keep the mouth open, but not enough to completely flush the lower depths which still contain some older salty water.  It will be very interesting to see if tomorrow's results have improved the lower depths given we've had a fantastic month of autumn rainfall which has resulted in the first sign of freshwater inflows into our estuaries.  Regards Jarred.
