Very  high D.O. reading noted, thanks.  Will see how next month goes, but it looks like the calibration worked fine, so maybe a dense pocket of algal??  Happy to check the meter as well in November readings stay this high.  Thanks Jarred.

Great data set as well, which aligns very well with H1 and H2 results - in that the top 1.5m is currently dominated by highly oxygenated and turbid freshwater (max depth here 1.2m).
