Jarred - great results as well.  Looks like a freshwater bloom happening up at Fonterra as well, with D.O.s very high!!

Dusky Moorhen, Reed Warblers, Pacific Black Ducks.

 

Jarred - thanks everyone.  Interesting to see the DO's in the upper water levels are on the rise - most likely being driven by warmer surface water driving algae growth, typical of the summer season.

Thanks again Gary & Rachel.  Very fresh and turbid profile!  

As flagged Gary, we're currently looking at artificial opening at the Cutting so this information, particularly a consistent D.O. profile at or above 5mg/L, is really important to support such decision.  

Regards Jarred.

Water level high.  Stairs were cut off.  Had to enter pontoon on ramp.

Water was brown and murky.
