Egret, Pacific black duck (2)

Great readings everyone - very consistent and dominated by winter freshwater following recent wet weather.  Thanks Jarred.

Great data also.  Like the lower estuary site, June rainfall has increased streamflow and created a highly oxygenated freshwater profile.  Temps are dropping too!!  Great work, thanks.  Jarred O.

Hi everyone, great data set once again & looks like some late season algal blooms have been persisting - shown by the high DO readings.  Typical of the Merri however, as Nitrate and Phosphurus levels are generally elevated in the catchment.  Thanks.

Little pied cormorant, Moorhen, Pacific black duck.

 

Thanks again guys, really good results.  Some interesting D.O. readings (high), but quite expected due to on-going dry and warm weather.  Basically indicates some additional oxygen producing activity occurring, which most likely is algal growth/bloom.  Thanks Jarred.
