Didymo infestation - Herald thinks water the answer.
Eh? Some extra water will get rid of didymo? "Flush" it? That is preposterous. They have to put something in the water - fast flowing water is what didymo prefers. It may very temporarily (like during the 24 hours) stop the spread upstream, but really?
Canterbury Regional Council don't mention anything about didymo - just a flood advisory. Nothing at Didymo News either. Nothing at Biosecurity NZ. No actions recorded since the middle of last year.
Could the above imaged NZ Herald story be bullshit? Looks like it. Someone's got the wrong end of the stick, and it's not me.
I've posted on didymo before, many times.
This is why they are "flushing" - their chart suggests they are at the maximum upper operating height. The lake is full. Their website says nothing about didymo.
