Lake-water it is healthy resource?The main input to the lake-water include
As the river water velocity reduced when entering lake, this lead to settle the particulate matter and producing lower suspended solids. Reducing turbidity and relatively long retention time in lake encourage the growth of some types of aquatic organism, where greater penetration of sunlight facilitates photosynthetic activity and growth of algae. A phenomenon that often has great impact on water quality in lakes is thermal stratification, caused by the lower density of warm surface waters in the summer. The temperature differential may isolate the lower strata of lake, prevent reaction of that water, and produce low or zero dissolved oxygen concentrations below dept of 7 meters. That can impact severely on water quality for supporting fish and other aquatic life that required dissolved oxygen. It also can produce conditions that favor the growth of organisms that develop undesirable taste and odors in water. The anaerobic conditions also can cause solubilization of iron and manganese in both deposits, producing concentration in the water that makes it unacceptable for municipal supplies unless appropriate(costly) treatment required before utilized.
