Organic C burial rates and lignin phenols in sediments were measured for six lakes. The results showed eutrophication over the last century in three lowland lakes. Terrestrial organic matter contributed to increased C burial in one lowland lake. These patterns were not observed in three mountain lakes. Lignin phenols clearly reflected watershed vegetation estimated by GIS.
