Abstract

Reservoirs play a key role in balancing the hydrological cycle and in providing water for drinking municipal industrial irrigation and consumption. Since all biological reactions occur in water its pollution becomes significant as it affects the biological system. The maintenance of the healthy aquatic ecosystem depends on the physical and chemical properties of water as also on biological diversity of the ecosystems Agarwal et al. 2000. Lentic ecosystem is the treasure house of varied biotic communities. The biodiversity provide and maintain ecosystem stability and is the very basis for sustainable development for the aquatic systems. This provides a model for the development of the biodiversity strategies. Plankton ascertain the historical background by their existence.the rivers are the best home for the flora being an index of water status. Aliyar reservoir is situated in Aliyar township just below the Anaimalai Hill ranges at a distance of 20 km from Pollachi town 10 20; N 76 57; E. This receives water from Aliyar Basin with a catchment area of 122 m the streams contributing to this being Aliyar Chinnar and Sithar. A feeder channel also brings the water from Thunakkadavu Parambikkulam to aliyar reservoir to augment its supplies. The maximum water spread is 41 m 135; and the mean depth 16.8 m 55;. Aliyar reservoir is studied for its diverse nature of the biotic components such as phytoplankton.
