College (Magadh University), Patna-800 001, Bihar, India > Research Paper 2017 7 10 2017 09 22 This study was aimed to assess status of physico-chemical characteristics of two floodplain lakes, Tarawe chaur and Gamharia chaur of north Bihar, India. Floodplain lakes are fresh water wetlands situated on the flood plains of river Kosi at 26°8\' N latitude and 65°5\' E longitude. The lakes get inundated with flood water during monsoon season and retain perennially. Monthly changes in physico-chemical variables were analyzed from November 2012 to October 2013. The existing water quality in two floodplain lakes was identified in terms of physico-chemical characteristics. Rainfall, evaporation, changes in water level, water from catchment and climate are major factors that determine quality of water in the floodplain lakes. The physico-chemical parameters, such as transparency, conductivity, pH, dissolved oxygen, chloride, nitrate-nitrogen and phosphate-phosphorus and BOD show lacustrine and riverine conditions. The water quality variables suggested that floodplain lakes offer a good habitat to supports many aquatic species. Results of present study indicate pollution free water at Tarawe chaur, and slight poor water quality at Gamharia chaur due to the waste water inflow from nearby village. The obtained value of physico-chemical parameters compare with the range reported from wetlands of other regions. The relationships among water quality parameters were tested by correlation co-efficient (r) analyses. Copyright@ International Science Community Association
