Destratification of hypolimnetic waters produces circulation that moves dissolved oxygen into the anoxic hypolimnion of reservoirs. Destratification increases the dissolved oxygen content of anoxic water and results in decreased concentrations of the dissolved forms of iron, manganese, ammonium, phosphorus, and hydrogen sulfide. Aeration also affects water pH and temperature and redox potential, which change the transformation rate of various chemicals in reservior ecosystems. A thorough review of existing literature indicates that the factors affecting oxidation of nutrients and metals are highly site specific. This report discusses oxidation pathways of chemicals and important environmental parameters that affect the transformation rate of selected nutrients and metals in lakes and reserviors and presents a model for predicting the transition from anaerobic to aerobic conditions.
