In these definitions the process of eutrophication, rather than trophic state, is being defined. Lakes that are shallow or possess extensive littoral zones with well developed macrophyte communities and are undergoing relatively slow rates of nutrient input tend to remain dominated by macrophytes under eutrophic conditions. Oligotrophic vs Eutrophic Lakes. Initially, eutrophic lakes accelerate multiplication and growth of lake fauna due to the high levels of oxygen provided by a large number of plants growing in the lake. Whether a eutrophic lake is dominated by either macrophytes or blue-green algae depends on the pre~impact condition of the lake and nutrient loading rates.

Based on the trophic state* and productivity, the lake ecosystem is divided into three categories. Nutrients carried into water bodies, such as agricultural runoff, residential fertilisers, and sewage will all increase the algal biomass, and can easily cause an oligotrophic lake to become hypereutrophic. Oligotrophic lakes do not contain a high level of nutrients. When a lake becomes shallower from added sediment, even more plants can grow because the littoral area (the area of the lake that is shallow enough for light to reach the bottom) increases in overall percentage. eutrophic: Rich in mineral and organic nutrients that promote a proliferation of algae and aquatic plants, resulting in a reduction of dissolved oxygen. Eutrophic lakes or water body is one with relatively highlevels of biological productivity. When algae dominate, the water tends to be darker.
