In many impoundment dynamic water quality models, the growth of two or more ecologic groups of phytoplankton may be simulated. These ecologic groups are differentiated by growth rates, temperature tolerances, settling rates, and the Michaelis‐Menten half saturation constants for necessary nutrients. In this investigation, the effect of variations in the Michaelis‐Menten half saturation constant for the limiting nutrient when two competing ecologic groups of algae are simulated is examined. In an idealized case, it is demonstrated that uncertainty in the half saturation constant for the limiting nutrient for one ecologic group of algae can significantly affect the simulation results and in some cases could lead to a poorly designed impoundment restoration program.
