What a Sad buzz! Remember guys we are the Caretakers - Words from ol mate and Waikato Local Erin Tinsdale "Please share this post.
A most terribly sad day for me, the locals of Putaruru, nz and most of all, the awesome little guys that used to populate the Oraka stream bellow my house. Took my kids down to the Oraka river near the Waihou and was mortified to witness thousands (no exaggeration) of poisoned Koura rolling downstream hour after hour!
Have enjoyed catching and releasing trout in this beautiful spring fed stream. Feel like i am mourning a lost friend to see this. Its has killed the lot! Will take decades or more to recover.
Regional council have arrived to do testing.
Bit by bit we lose more and more of beautiful nz".

Scientific analysis of the water samples revealed nothing that clearly identified a likely cause of death.
"While it's good news that there have been no further deaths of koura, we're continuing this week to eliminate potential causes as part of our ongoing investigation," Hartley said.
He encouraged anyone with information on the possible cause of the koura deaths to contact the council on 0800 800 401.
