Blue green algae found in Tingwall
Another loch has been found to contain blue green algae, this time the Loch of Griesta in Tingwall.
Notices will be posted next to the loch warning against contact with the algal scum.
The SIC’s environmental health department received notification of the discovery from the Scottish Environmental Protection Agency. Adjoining landowners NHS Shetland and Shetland Angling Association have been made aware of the situation.
There is no adverse effect on water supplies at this stage. Blue green algae has effected a number of lochs this year, including in Voe and Twatt.
