Abstract: Present study deals with the analysis of the current status of Physico-Chemical parameters of water samples collected monthly from four different monitoring stations of Dilawara reservoir of Dhar district, Madhya Pradesh during January 2017 to December 2018 by using different standard methods, procedures, and instruments.The water temperature, transparency and pH were measured in-situ by using 0.1scale Mercury thermometer, Sacchi disc and pocket type digital pH meter respectively. The remaining parameters were determined ex-situ in the laboratory as per the standards. The results indicated that most parameters were within the permissible limit except for the pH, DO and COD which indicated the pollution in reservoir built for storing water to be used for irrigation, human consumption and pesiculture.The water quality index (WQI) calculated for the year 2017 and 2018 by computing mean values of 13 important parameters with the help of weighted Arithmetic method reveals that water quality is in medium to bad range (WQI= 49 - 69).HenceDilawara reservoir, an important drinking water source of Dhar tehsil is not suitable for useunless treated prior to consumption. Therefore urgent and immediate actions are required for its propermanagement to restore the quality of the water andfor its long time surveillance. Keywords: Dilawara reservoir, water quality, physicochemical parameters,water quality index.
1. INTRODUCTION Availability of safe and reliable water is an essential prerequisite for sustained development (Adakole et al., 2012).It is important to constantly protect and control the quality of water (WHO, 2011).Over-growing population has resulted to the impoundment of many dams and reservoirs. It is therefore necessary to maintain our reservoirs by addressing the consequences of present and future threats of contamination and degradation of our water bodies. The monitoring of quality of surface waters by estimating hydrobiological parameters is among the major environmental priorities as it permits direct assessment of the status of ecosystems that are exposed to deleterious anthropogenic factors (Vandysh, 2004).Essentially, the surface water quality is characterized by various physico-chemical characteristics, and these parameters are prone to change owing to different kinds of pollution, seasonal fluctuation, and water extraction, etc. (Vasanthy and Velmurugan, 2009). The alteration in physico-chemical parameters leading to eutrophication has become a widely recognized problem of water quality deterioration (Jayakumaret al., 2009).The literature reveals that there is no scientific study carried out with respect to ecological characteristics of Dilawara reservoir, Hence this study was designed to monitor its water quality parameters, so as analyse its status and suitable through the potability and agriculture, pisciculture and drinking water quality point of view.
2. MATERIALS AND METHODS Sampling Sites: The proposed investigation was carried out in the fourselected sampling stations of Dilawara reservoir located in Dhartehsil of Dhar district, Madhya Pradesh,India.
