Hypolimnetic oxygenation is a relatively new management technique that averts hypolimnetic anoxia and its harmful consequences by oxygenating the hypolimnion using pure oxygen gas. This paper discusses a number of issues related to hypolimnetic oxygenation including advantages of hypolimnetic oxygenation systems over traditional aeration methods (e.g., destratification, aeration). It also discusses facility requirements and costs associated with various types of oxygenation systems, and the effects of oxygenation on water quality. Includes 28 references, tables, figures.
