Test results on possible algal blooms and discolouration affecting parts of Lake Tarawera have returned at an amber level but an ongoing warning hasn't stopped people enjoying the water.
Earlier this week Lake Tarawera users were being urged to be vigilant, following reports of possible algal blooms and water discolouration.
The Bay of Plenty Regional Council said it had received a number of reports of possible blooms and discolouration affecting parts of the lake, including the Wairua Arm (near Hot Water Beach) and the area around the campsite at the outflow of the lake.
Algal blooms can be caused by potentially toxic cyanobacteria (also known as blue-green algae).
A spokeswoman for the council said today the advice issued for the public to be cautious about recreational use at the area still stood.
