Abslract. Results of a joint project of EAWAG and GEOECOMAR on the nutrient retention capacity of Lakes Uzlina, Matita and Rosu within the Danube Delta are reported in this paper. Two expeditlons were organized, first in June and the second in September 1999. Special emphasis was placed on processes of nutrient cycling at the sediment-water interface. lt has been canied out water analyses, benthic flux chamber experiments, denitrification experiments, porewater analyses, measurements of

Methane production and the distribution of methanogenic and sulfate reducing microorganisms in the sediment has been analyzed. The dataset contains very important information on the self-cleaning capaclty of the delta lakes.
