Photosynthetic rates of algae in small lakes vary according to the concentration of dissolved oxygen (DO) in the water and the amount of direct sunlight hitting the surface. In spring of 2012, we conducted a five-week survey of dissolved oxygen concentration, local light level variation, and temperature fluctuation around Cedar Lake to determine how direct solar radiation (PAR) and temperature affect photosynthetic production and dissolved oxygen concentration. We expected that dissolved oxygen levels in the lake would be directly related to the amount of sunlight hitting the system rather than to the local water temperature on any given day. From our data and analysis, however, we concluded that dissolved oxygen levels were correlated, not with the amount of solar radiation hitting a given sector of the Lake, but with the average temperature of the different collection sites.
