CIPEL monitoring

Learn more about Lake Geneva to preserve it better

Preserving the health of Lake Geneva: that's what CIPEL is all about. of the CIPEL. Chis-presupposes knowledge of its condition, a program of regular monitoring of Lake Geneva was set up in the 1960s, in order to establish as complete a picture as possible of its state of health.

An essential assessment to identify issues requiring action to be taken to reduce the impacts impacts, by addressing the many factors governing the functioningof this ecosystem.

Each year, CIPEL and its partners produce scientific reports analyzing the latest results of monitoring campaigns and specific studies. They are available in our Limnothèque.

Global monitoring

The monitoring program set up and coordinated by coordinated by CIPEL is a reflection of the ecosystem: a combination of multiple parameters parameters, combining physics, chemistry and biology. Measurements and analyses are carried out in the lake's various compartments water, fauna, flora and sediment.ments.

Historical data

To help us understand the lake's evolution, but also to make forecasts for the years to come, it is particularly interesting, if not essential, to rely on long-term chronicles of data. Lake Geneva is exceptional in that it has data spanning several decades for certain parameters (temperature, pH, phosphorus, oxygen, water transparency, etc.) - a rare situation for a lake.

Although scientific studies had already been carried out, it was only in the early 1960s that the scientists around the lake joined forces to organize joint monitoring, foreshadowing the creation of CIPEL in 1962. Since then, the monitoring program has expanded, with long-standing and therefore valuable chronicles being kept.
