A kind of chromatographic sedimentation of the land-derived particles with different specific gravity was suggested from the river mouth to the mid-lake. The size distributions of the isotope ratios support this inference. Denitrification and the associated oxidation reduction reaction seemed to enhance the <SUP>15</SUP>N content of sedimentary organics during epidiagenesis of the sedimentary organic matters. The isotopic compositions of the sedimentary organics and the soluble nitrogenous compounds can be useful indicators to characterize a biogeochemical structure of a lake system. Significant increase in δ<SUP>13</SUP>C of sedimentary organics by 3% and in δ<SUP>15</SUP>N of NO<SUP>-</SUP><SUB>3</SUB> and DON by 2 to 7% were found under eutrophication caused by human impact, in the highly eutrophic lake, Lake Suwa.
