LAKE AND POND AERATION
The most important function lakebed aeration serves is to provide oxygen to the bottom of the lake where organic nutrients and sediments accumulate. The source of these nutrient and sediment inputs include decaying leaf matter, decaying aquatic vegetation, fish feces, waterfowl feces, storm runoff, and nutrients from irrigated lawn areas surrounding the lake.
Without aeration, these nutrient rich sediments accumulate on the bottom in a low or no oxygen environment and are subject only to anaerobic microbial decomposition. Anaerobic decomposition is a very slow and ineffective process and one of the primary byproducts of this process is hydrogen sulfide which results in a rotten egg odor. Anaerobic conditions at the bottom of a lake also results in the release of these nutrients from the sediments where they are readily available as the primary ?food? source for algae (moss) and other aquatic vegetations.
Providing oxygen to the bottom of the lake allows for aerobic microbial activity which is more effective at decomposing sediments and nutrient, as well as keeping the nutrients entrained in the sediments thus reducing their availability for aquatic plant utilization.
Another benefit of a low velocity lakebed aeration system is to provide a well oxygenated environment at greater water depths for utilization by the fish in the lake or pond.
Without aeration most deep lakes thermally stratify during summer and winter months creating a layer of warmer water over a layer of cooler weather in the summer, and vice versa in the winter, leading to a condition where only the top layer of water is adequately oxygenated and suitable for fish use. The cycle of stratification can be broken by mixing the lake water from the bottom to the top with low velocity aeration. This mixing creates a more uniform temperature in the lake and provides oxygenation to all layers in the water column.
