Boaties are being warned to beware treacherous booby traps hidden below exceptionally high lakes levels in the Rotorua Region.
A number of lakes in the area have water at levels that haven't been seen since since the 1970's.
In some cases that means whole boat ramps and picnic tables are submerged.
Add to that a flood of summer visitors and it's a recipe for extreme caution.
The Bay of Plenty Regional Council Senior Maritime Officer, Roly Bagshaw describes how the lakes are looking.
