The characteristics of water are proportional to environmental quality around it. An attempt has been made in the current research to assess various characteristics of the physico-chemical quality of water and significant factors in determining biodiversity in Pichola lake, Udaipur. Most importantly various anthropogenic activities, for example mining, soil erosion, religious activities, hospitality industry, etc., are responsible for downgrading the water quality of the Pichola lake. A significant impact of the anthropogenic activity, like mining, discharge of sewage effluent and excessive use of agrochemicals is affirmed. In this research study, we have measured pre and post-monsoon physico-chemical parameters and computed water quality index, eutrophication index and organic pollution index. Parameters, pH, EC, alkalinity, TDS, phosphate, COD and nitrate of Pichola lake are within acceptable limit; however, chloride content, dissolved oxygen and post-rainfall BOD are beyond the permissible limit. Therefore, present study provides essential information about deteriorating water quality of Pichola lake.
