Water Quality: Management, Sanitation and Investigation

Water Quality Restauration

Limitation of light

The deep lakes and reservoirs have the option of reducing the growth of phytoplankton by artificially circulating (mixing) the water body all year round. The algae cells enter into the deeper water visible with little light. Reduction in availability of light is possible in very narrow water reservoirs by planting trees at the north end of the shore.
