Abstract

The water samples of Nang spring, Khan (Pluoro), Pluoro and Kenhein torrents were collected for water quality and biological life. The water samples were analysed for physico- chemical parameters. The water indicates conductivity and total dissolved solids within the range of 30409000 µS/cm and 1945-5760 mg/l respectively. The spring water flow rate was about 60100 l/h in the form of small stream. Phragmites australis Trin, Scripus tuberoses and S. littoralis are growing in water logged and shallow water pools. Chara zeylanica, (L.) Najas minor, Potamogeton pectinatus, Typha domingensis and Vallisineria spiralis were present in the pools in the form of patches. Besides these plants, 16 species of Cyanophyta, 11 species of Chlorophyta, Gyrosigama kutzingii and Riccia sp. have also been recorded from these springs.
