By January 2004, data on 314 lakes from 34 types were submitted by 25 countries. From the 68 class boundaries (two for each type) 25 were represented by a sufficient number of lakes five or more. Mostly data on hydrochemistry (263 cases) and phytoplankton (214 cases) were used in the preliminary quality assessment, followed by data on angiosperms (87), benthic invertebrates (76) and fish (29). These numbers reflect also the availability of data for lakes.
