Lake growth is a term used to describe the process of a lake increasing in size due to the accumulation of sediment, organic matter, and other materials. ALGAE is an important part of this process, as it helps to increase the nutrient content of the lake, which in turn encourages the growth of aquatic plants and other organisms. ALGAE also helps to reduce the amount of light that reaches the lake bottom, which can help to reduce the rate of evaporation.
