This paper is devoted to the varying concentrations of 49 elements found in the water from three littoral sites and one pelagic site, sampled over a five hour period, in Lake Lacawac. These elements were detected in concentrated water samples by use of X‐ray emission and optical emission spectroscopy. The elemental concentrations of the four sampling sites differed. Statistical analyses were used to estimate how chemical mixing proceeded in the surface waters of the lake. Results from a previous study of the chydorid Cladocera living in the sediments beneath the water sampling sites indicated that the more organic sediments contained more individuals than the sandy sediments. The chemical concentration of the water followed the same distribution as did the organisms.
