Why monitor the lake?
The ASL was created in 1980 when the lake was suffering from eutrophication (a shortage of oxygen). Through its work, the ASL has made a significant contribution to improving water quality.
Today other threats, such as plastics, micropollutants and invasive species are less visible but just as worrying.
Thanks to its many members who keep a constant lookout for Lake Geneva, the ASL is regularly alerted to potential issues with pollution or other threats to the lake. This allows it to act swiftly to put pressure on the authorities or propose solutions to preserve the quality of the lake’s water and its wealth of biodiversity.
