Windy, rainy weather decreases blue-green algae in lakes

The national cyanobacterial situation has improved slightly since last week, said the Finnish Environment Institute (SYKE) in a press release on Thursday.

The number of cyanobacterial observations in lakes has diminished as a result of the windy and rainy weather, and the situation in inland waters is still better than usual.

The poor cyanobacterial situation in sea areas has also improved somewhat, but more cyanobacteria have still been observed than on average in recent years.

Observations have been made especially in coastal areas of the Archipelago Sea.

The national cyanobacterial monitoring is carried out as part of the monitoring of the state of the environment in cooperation with the Centres for Economic Development, Transport and the Environment (ELY Centres), municipal environmental and health authorities and the SYKE.

Finnish Rotary Clubs are also actively involved in nationwide cyanobacterial monitoring.
