Tega-numa (Lake Tega) is one of the eutrophic lakes in Japan. For the improvement of water quality in Lake Tega, the North-chiba Water Conveyance Channel was constructed in , which transfer water from Tone River into the lake. After , the dominant species of diatoms, mainly Cyclotella sp., have been replacing blue-green algae, mainly Cited by: Heterotrophic potential for amino acid uptake in a naturally eutrophic lake.

Eutrophication (from Greek eutrophos, "well-nourished"), or hypertrophication, is when a body of water becomes overly enriched with minerals and nutrients which induce excessive growth of algae. This process may result in oxygen depletion of the water body. One example is an "algal bloom" or great increase of phytoplankton in a sandy body as a response to increased levels of nutrients. (biology, of a body of water) Being rich in nutrients and minerals and therefore having an excessive growth of algae and thus a diminished oxygen content to the detriment of other organisms.

There™s also a related, social factor: where lakes are naturally eutrophic, lake users are more tolerant of algae (Heiskary and Walker , Smeltzer and Heiskary ).

Organic nitrogen is introduced to sediments via either external (allochthonous) or internal (autochthonous, NFIX) mechanisms. The breakdown of sediment organic nitrogen occurs in several phases. Particulate organic nitrogen (PON) can be mineralized directly to ammonium (NH 4 +) or it may be metabolized to dissolved organic nitrogen (DON), which is further mineralized to NH 4 +.
Carlson's Trophic State Index. Carlson's index was proposed by Robert Carlson in his seminal paper, "A trophic state index for lakes". It is one of the more commonly used trophic indices and is the trophic index used by the United States Environmental Protection Agency.
The trophic state is defined as the total weight of biomass in a given water body at the time of measurement. Other articles where Eutrophic lake is discussed: Alpine lakes: multiply, in a process called eutrophication. The extreme growth of phytoplankton under these conditions makes the water turbid and less suitable for bathing.
It also intensifies oxygen consumption in the deep layers of the lake as a result of the increased decomposition of dead algae. A lake in a nutrient-rich region may be naturally eutrophic. 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.
Flux chamber experiments showed negligible amino acid flux out of the sediments in untreated chambers, but rates of amino acid flux ranged from 27 to 69 mgN m−2 day−1 (= 81– mg C.m−2.

The trophic state index (TSI) score places a lake into a category of oligotrophic, mesotrophic, eutrophic, or hyper-eutrophic. Lakes naturally occur in each of the first three categories, but hyper-eutrophic lakes are within that category because of human-caused nutrient enrichment.

The effects of resuspension and macrophytes as well as oxygen availability were determined, as was the role of natural nitrogen (N) removal (denitrification).

White Lake is characterized by two basins of about 20 m maximum depth, a mean depth of m, a mean volume of about × m 3, and a surface area of × m 2 (Fig.

Some types of nutrient-rich pollution .The trophic state of a lake is a hybrid concept with no precise definition. Originally, trophic referred to nutrient status.
Eutrophic water was water with high concentrations of nutrients and, by extension, a eutrophic lake was a lake that contained eutrophic water. Later the concept of trophic state was applied toFile Size: KB.
