    The main effects caused by eutrophication can be summarized as follows: 1. Species diversity decreases and the dominant biota changes. 2. Plant and animal biomass increase. 3. Turbidity increases. 4. Rate of sedimentation increases, shortening the lifespan of the lake. 5. Anoxic conditions may develop. Eutrophication, defined as the nutrient enrichment process (mainly nitrogen and phosphorus) of any water body which results in an excessive growth of phytoplankton and macrophytes [1, 2, 3], has become a major cause of concern in developing as well as developed countries [].Also, it was recognized as a pollution problem in the European and North American lakes and reservoirs in the mid.

    Lake restoration, and in particular fish removal in shallow eutrophic lakes, has been widely used in Denmark and the Netherlands, where it has had marked effects on lake water quality in many lakes. Long‐term effects (> 8–10 years) are less obvious and a return to turbid conditions is often seen unless fish removal is repeated.   Limnologists have long studied the processes that cause some lakes to have low concentrations of algae (oligotrophic) and others to become highly turbid due to algae blooms, or eutrophic (1, 2).This research has led to understanding of eutrophication, a significant environmental problem. Consequences of eutrophication include excessive plant production, blooms of harmful .

    Stormwater diversion does not have the capacity to restore shallow eutrophied lakes. Abundant phosphorous already accrued in the lake leads to high internal nutrient loading. The act of diverting phosphorous laden water does not effect the phosphorous already accumulated in the lake. The fraction of phosphorous removed produces negligible results. Eutrophication of lakes and reservoirs has become one of the most obvious and pervasive water quality problems in the world today. Protection of clean water systems and restoration of eutrophic water bodies is badly needed. This new book addresses this need, and deals specifically with lake and reservoir restoration techniques.

Many lake ecosystems worldwide experience severe eutrophication and associated harmful blooms of cyanobacteria due to high loadings of phosphorus (P). While aluminum sulfate (alum) has been used for decades as chemical treatment of eutrophic waters, the ecological effects of alum on coupled metal and nutrient cycling are not well by: Effects of diversion and alum application on two eutrophic lakes.

Interventions operate in two general ways: reducing contaminant levels in the receiving environment (e.g. lake and estuary flushing, in-lake alum application and sediment capping; Özkundakci et.

Application of aluminum sulfate to the hypolimnion of West Twin Lake, a hardwater eutrophic lake in northeastern Ohio, did not efficiently remove complex phosphorus compounds from the water column. The majority of the complex phosphorus compounds remaining after alum treatment released P04 following brief treatment with alkaline phosphatase.

Eau Galle Reservoir, Wisconsin, was treated with a hypolimnetic dose of aluminum sulfate (alum) in to diminish excessive phytoplankton production associated with high phosphorus loading from anoxic, profundal sediments. Prior to treatment, internal total phosphorus (TP) loading was 3 to 6 times greater than external TP loading during summer stratification.

Aluminium sulfate (alum) was applied to Lake Okaro, a eutrophic New Zealand lake with recurrent cyanobacterial blooms, to evaluate its suitability for reducing trophic status and bloom frequency. The dose yielded g aluminium m–3 in the epilimnion.

In some cases, a lake is eutrophic simply as a result of natural circumstances (e.g., ecoregional characteristics), but nonpoint pollution from agricultural and urban run-off is the cause of use impairment from excess nutrients in most lakes.
