Lake Information

Toxic algal blooms

In summer, some of our lakes can be prone to toxic algal blooms. This blue-green algae can cause health issues in adults, children and dogs - so keep out if there's a warning, and always look before you leap.

Avoid any recreational contact with lakes and rivers if they:

• look discoloured
• have an unusual smell
• have green or brown particles suspended in them, or
• have scum or leathery mats of algae on the surface or on the bottom of the waterway, or along the shoreline.

Where to find lake level information

You can use the Environmental Data Portal on the Bay of Plenty Regional Council website to view an up-to-date map of Rotorua lakes and their level status.
