A sharp-eyed member of the public has got the Waikato Regional Council investigating why the water at popular tourist spot Bridal Veil Falls has suddenly turned into a shade of "cow poo".
The Hamilton man said that he noticed the discoloured water after spying a photo that a visitor had taken and posted on their Facebook page.
"Hi WRC, saw these photos on a visitor's feed, and wondered why Bridal Veil Falls is the exact colour of cow poo at the moment?
"What's going on upstream that our beautiful place looks like an effluent pond ... not impressed."
