Measurements of phytoplanktonic productivity and certain physical and chemical characteristics were made over a one-year period, 25 September 1968 to 27 September 1969. Temperature and dissolved oxygen profiles showed the lake to be in a nearly continual state of holomixis. A slight gradient in these measurements existed briefly in summer and under the ice. Hydrogen ion concentration and total alkalinity varied little throughout the study. Values ranged for 7.9 to 8.3 pH and 94 to 111 ppm for alkalinity. Transparency ranged from 1.2 to 3.9 m. Productivity was measured using Carbon-14 methodology. The graph of integrated productivity generally followed the seasonal trend of water temperature. Assuming that he incubation period represented 45% of total daily isolation, the estimate of daily mean productivity for the year was 116 mg C m-2. Abnormally high dark bottle uptake encountered periodically may have resulted in an underestimation of productivity.
