Follow-up of the CIPEL

Better knowledge of Lake Geneva to better preserve it

Preserving the health of Lake Geneva, this is the major stake of the CIPEL. Chis is a pre-presupposes to know it, a program of regular monitoring of Lake Geneva has been set up since the sixties, in order to draw up a state of health as complete as possible.

An essential assessment to identify the issues requiring actions to be taken to reduce the impacts the impacts it suffers, by looking at the many factors governing the functioning of thisof this ecosystem.

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

A global follow-up

The monitoring program set up and coordinated by coordinated by the CIPEL is like the ecosystem, that is to say a combination of multiple parameters, mixing physics, chemistry and biology. The measurements and analyses are made in the different compartments of the lake, which are water, fauna, flora and sediment.ments.

A history of data

To help understand the evolution of the lake, but also to provide information for forecasts for the years to come, it is particularly interesting, and even essential, to rely on long time series of data. Lake Geneva is exceptional in that it has data over several decades for certain parameters (temperature, pH, phosphorus, oxygen, water transparency, etc.); a rare situation for a lake.

Although scientific studies had been carried out before, it is at the beginning of the sixties that the scientists associated themselves around the lake to organize a common follow-up, prefiguring the creation of the CIPEL, in 1962. The monitoring has since been expanded, keeping long-standing and therefore valuable records.
