Rahane Balasaheb1 , Waykar Bhalchandra2 and Bhalla Resham3 Received: 30.07.2015 Revised: 28.09.2015 Accepted: 5.10.2015 Abstract The seasonal physico-chemical parameters like temperature, pH, total alkalinity, dissolved oxygen, total hardness, chlorides, salinity and electrical conductivity were determined seasonally from Girna, Ozarkhed, Chankapur and Gangapur reservoirs of Nasik district. Results of the present study indicated that the mean values of temperature, pH and total alkalinity were highest in summer season and lowest in winter season, mean values of dissolved oxygen was highest in winter season and lowest in summer season. The mean values of total hardness, salinity, chloride and electrical conductivity were highest during summer season and lowest during monsoon, in surface water sampled from four studied reservoirs. Thus result clearly indicated that the surface water of Girna reservoir was more polluted than other three reservoirs, while surface water of Gangapur reservoir was less polluted than other three studied reservoirs. Keywords: Physico-chemical parameters, reservoir, seasonal variations Introduction Water quality is affected by both point and non- reservoirs of Nasik district. point sources of pollution. These include sewage Study Area discharge, discharge from industries, run-off from Four reservoirs of Nasik district were selected for agricultural fields and urban run-off containing the study. The details are given below: various organic and inorganic pollutants, such as Girna reservoir: Girna reservoir is earthen dam solvents, oils, heavy metals, pesticides and constructed in 1969 on Girna river at Nandgaon in fertilizers are invariably discharged into small Nasik district of Maharashtra state, India. rivers, streams without their proper treatments Geographically, reservoir is located at 20°29'16" N (Pandey et.al., 2003).

Therefore, regular monitoring of water content of reservoir is 2,042 Km3 (490 cu mi) and quality is essential. The monitoring and assessment gross storage capacity is 608,980.00 Km3 of water quality is depending upon the basic (146,102.07 cu mi). The reservoir water is used for physico-chemical properties of water. Therefore in irrigation, industrial as well as for drinking purpose. the present study the physico-chemical parameters Ozarkhed reservoir: Ozarkhed reservoir is earthen like temperature, pH, total alkalinity, dissolved reservoir, constructed in 1982 on Unanda river at oxygen, total hardness, chlorides, salinity and Dindori in Nasik district of Maharashtra state, electrical conductivity were determined seasonally India.
