Järviwiki’s goal is to share information about Finnish lakes, promote water protection and increase interest in waterways. It is a public service where anyone can participate sharing information and contents. The web service is built and maintained in cooperation by authorities and common people. The first version was released in March 2011.
In the web page you can find information about algae growth, surface water temperature, ice cover and pollution in Finnish lakes and jellyfish presence in Baltic Sea.
