CCME Water Quality Index and Assessment of Physico- Chemical Parameters of Chikkakere, Periyapatna, Mysore District, Karnataka State, India

A water quality index (WQI) developed by the Canadian council of ministers of the Environment (CCME) was applied to chikkakere , a lake at Periyapatna, Mysore district , Karnataka state, India to study its impact on the protection of aquatic life. The index in the lake is rated as poor.
