levels, which causes poor light penetration. There is low dissolved oxygen and shallow water. This all causes higher algal growth. The bottom of the lakes are made of silt, sand or clay. Carp, bullheads or catfish can be found in the lakes. Eutrophication is a serious concern for lakes as it can turn an oligotrophic body of water into a eutrophic body of water, which is dangerous to the ecological diversity. 2. Most natural transistions from an oligotrophic water body to an eutrophic water body

Eutrophication is defined as the natural ageing process of natural body of water, generally understood to refer to enrichment of water systems by nutrients, notably phosphorus and nitrogen, and to the improved production of algal and higher plant biomass that the added nutrient loads stimulate (Reynolds, 1992). Customarily, the eutrophication is a natural phenomenon, but during the past decades, the word ‘eutrophication’ has been frequently used to signify the

The National Oceanic & Atmospheric Administration (NOAA) explains that if this trend of eutrophication continues, what is known to be a “dead zone” will be created. According to the NOAA, the northern Gulf of Mexico is the second largest dead zone in the United States. The Gulf of Mexico is officially recognized as a hypoxic, or dead zone, because

farmlands increases the nutrient levels in streams leading to eutrophication, which decreases macrophytes and animal diversity (Huang). Some studies even concluded that the fertilizer used wasn’t needed in such high amounts as it was “high enough to result in soluble and total P concentrations in surface runoff from both unfertilized and fertilized watersheds that were consistently greater than critical levels associated with accelerated eutrophication” (Sharpley et al,). Problem Statement: The increasing

becoming a large problem in waterways throughout the world both in freshwater and marine systems. Because this issue is rapidly increasing, the sustainability of these aquatic systems should be addressed more prominently to prevent the process of eutrophication that occurs consequently of nutrient loading. What exactly is nutrient loading? According to the National Oceanic and Atmospheric Administration (NOAA), Nutrient pollution is the process where too many nutrients, mainly nitrogen and phosphorus

We found that the limiting nutrient in Loughberry Lake is phosphorous. The most natural way that phosphorous enters aquatic systems, is through the cycling and erosion of phosphorous rich rocks and sediments. The phosphorous cycle takes a long time to complete, but through human processes such as mining and runoff, phosphorous is able to enter our water sources much more quickly. There is also a small amount of deposition that may occur from the atmosphere to the water. The most common human source

greatly increases and as a result of this, the fish population is also increasing. This increase will continue as more and more phosphorus gets into the water. Excessive amounts of phosphorus in the water have been shown to be “the main cause of eutrophication over the past 30 years. This aging process can result in large fluctuations in the lake water quality and trophic status and in some cases periodic blooms of cyanobacteria” (Water Research Center). As phosphorus becomes excessive in the water

telling what a good level is and what a bad level is. If an excess amount of nutrients was found in the water, algae could be formed. When algae is formed it blocks sunlight from shining into the water, which creates dead zones. This is called eutrophication. A dead zone is an area where there is no life. This can cause major problems like population issues and more. If the algae continues to grow in the river, the whole body of water can die out, and people as well as other organisms are very dependent

water pollution in the United States, the largest of which is agriculture. Contributing factors are the use of fertilizer, tile drainage, and the need to feed a growing global population. Polluted water is the root of many environmental problems. Eutrophication, hypoxia, and algae blooms are caused by an excess of

[3] Agricultural Non-point Source Water Pollution Caused Eutrophication of Dianchi Lake in China and Possible Solutions Abstract: Eutrophication is a big problem around the world and especially in China where laws and regulations are not followed in rural areas. This is the case in Kunming, Yunnan, China at Lake Dianchi where eutrophication is the highest in the country. This case study will set up to study the effects of phosphate in the lake, the quantity of phosphate, and the possible
