The lake has been heavily polluted but its condition has been improved, and today the lake has both high economic and social importance for a significant proportion of the Finnish population. There is a long experience of lake research in the L. P\u00e4ij\u00e4nne area, including some long-term data series. Research at L. P\u00e4ij\u00e4nne is diverse and is already well-equipped with instrumentation supporting long-term monitoring. The research covers large scales from hydrology to fish stock assessment.  This research area includes also another large Finnish lake, Lake Konnevesi, as a natural reference lake in the northern branch of the Lake P\u00e4ij\u00e4nne system.","citation":null,"relatedIdentifiers":null,"status":{"label":"Operational","uri":"http:\/\/vocabs.lter-europe.net\/elter_cl\/10772"},"yearEstablished":2007,"yearClosed":null,"relatedSites":null,"siteName":"Lake
