One of the great tools in a lake manager’s tool box is the use of submersed aeration. Submersed lake and pond aeration adds oxygen directly into the water column and involves the mixing of water to increase exposure to atmospheric oxygen, thus, decreasing harmful gases like hydrogen sulfide with in the waterbody. This proactive management solution significantly helps promote positive changes in lakes and ponds; however, aeration systems must be properly sized and placed in order for aquatic ecosystems to fully reap the benefits. Surface mapping used in conjunction with depth-sensing technology, such as bathymetry, can help determine the correct size and location of aeration systems to ensure the entire waterbody is receiving adequate oxygenation.
Submersed pond aerators use diffused air to push water from the bottom of the pond to the surface, where it can be exposed to the atmosphere. The water on the surface then gets displaced and driven down to the bottom of the pond, creating circulation and mixing from top to bottom. This mixing creates a more uniform and oxygenated body of water.
