People have been urged to stay out of the water at a Powys reservoir after blue-green algae was found.
The algae, which produces toxins which can cause skin rashes, nausea, vomiting, stomach pains, fever and headaches, has been found at Llyn Clywedog near Llanidloes.
It occurs naturally in inland waters, estuaries and seas and cannot be removed or treated.
Powys County Council is recommending people not to swim, allow pets or livestock to come into contact with the water or eat fish caught in the reservoir.
Anyone who has come into contact with water containing blue-green algae should shower with fresh water immediately.
Anyone who has come into contact with affected water and has become ill should obtain medical attention.
People are advised:
- not to swim in the water or to become immersed, e.g. water skiing
- not to swallow the water
- to avoid contact with the algae
- not to eat fish caught in Llyn Clywedog
- not to allow pets or livestock to come into contact with the water
- to observe and abide by notices positioned around Llyn Clywedog
