Is Aeration the Answer?

Aeration, which is the mechanical circulation of oxygen in a lake, can be highly beneficial for a lake or pond. The primary benefit is the resulting increase in the dissolved oxygen content of the water, which increases the level of bacteria activity within the water column. The extra bacteria consume excess nutrients, helping to improve water quality. Aeration can also reduce lake stratification, enhance fish habitat and help prevent fish kills, and possibly help to control or reduce the occurrence of nuisance algae blooms. While an aeration system can be a terrific addition to an overall lake maintenance program, it isn’t a "lake manager in a box," and is neither necessary nor suitable for every lake. In addition, there are a number of different types of aeration systems, operating on different mechanical principles; it’s important to understand the functions and applications of the system type you’re considering before making a purchase. Aeration systems are major investments, and must be properly installed and maintained in order to be effective; long-term plans and goals, as well as the current uses and conditions of your lake, should be carefully considered in determining if aeration is an appropriate option.
