Abstract Lake Monroe is the largest body of water in Indiana with a daily mean productivity of 220 mg · C · m−2 · day−1 in an observed range from 26 to 714 m · C · M−2 day−1. It is a medium soft reservoir; the acid combining capacity varies from 0.28 to 0.71 meq · l−1 with a mean slightly above 0.5 meq · l−1. The results of diurnal changes in major nutrients, the C, N, and P ratios, and bioassay experiments indicated that phosphorus is the major limiting nutrient on algal photosynthesis in this lake. Surface photo-inhibition may be used to indicate the sufficiency of light for the species of algae in the water. The low productivity in December, January, February, and early March can be attributed to light limitation due to low water transparency.
