LAC installed 42 new aerators in the lake this summer, bringing the total number to 60. These aerators remediate pollution by circulating the water and adding dissolved oxygen. They operate from the bottom up, introducing oxygen where the lake needs it most and bubbling the air up through the entire water column to the surface. Constant lake aeration improves water quality by promoting biodegradation of lake sediments, reducing algae growth and odors, while enhancing fish habitat. The circulating water also reduces the amount of plant material present that will ultimately die and decompose.Decaying plants use oxygen and add nutrients in the form of nitrogen and phosphorus to a waterbody. These excess nutrients allow more algae and plant growth which is why adding oxygen and water circulation are so important for maintaining a healthy waterbody.
