Kerrowdhoo & Clypse Reservoir algal blooms

Update : 25/11/2014

Blue green algae is currently present in the Kerrowdhoo & Clypse Reservoirs. This is a natural phenomenon.

Although algal blooms aren’t always harmful, some can be toxic and so all visitors to the reservoir are strongly advised to avoid contact with the water and to prevent animals drinking from it.

The algae itself is removed during the water treatment process and does not, therefore, represent a danger to the drinking water in supply.
