dystrophic lake

There are also over 20 smaller dystrophic lakes in the Krutynia river basin.

Dystrophic lakes have high levels of humic matter and typically has yellow-brown tea coloured waters.

Although dystrophic lakes are often considered acidic, and nutrient-poor (oligotrophic), these lakes actually vary greatly in terms of both pH and productivity.

Dystrophic lake refers to lakes with brown- or tea-coloured waters, the colour being the result of high concentrations of humic substances and organic acids suspended in the water.

Naumann is also widely known for his contributions to lake typology, and specifically for introducing the terms oligotrophic, eutrophic and dystrophic lake to our modern lake classification.

Humic acid is a principal component of humic substances, which are the major organic constituents of soil (humus), peat, coal, many upland streams, dystrophic lakes, and ocean water.
