A yearlong study was made of the phytoplankton, seston, and dissolved organic carbon in a small, hardwater, midwestern stream. The annual cycle of cell counts and volumes followed the cycle in water temperature. The dominant algae were small, euplanktonic, centric diatoms of the genera Cyclotella, Melosira, and Stephanodiscus, which contributed an average of 63% of the cell count and 66% of the cell volume. The seston averaged 15.8% organic matter by ignition. Stream flow and particulate organic matter were positively correlated from December to April, negatively from May to November. The phytoplankton contributed an average of 38% of the particulate organic matter from May to November. The dissolved organic carbon averaged 6.4 mg/liter, and showed no seasonal cycle.
