The River Godavari is the largest of the peninsular rivers and the second longest river in India next only to Ganga. It is originated near Nashik (Maharashtra) in Northern Western Ghats. It flows across the Deccan Plateau from Western to Eastern Ghats through Maharashtra and Andhra Pradesh before emptying into the Bay of Bengal. It is a vital source of water for the people live surrounding villages, primarily for agriculture, aquaculture, domestic and industrial need. To assess the scale of water quality determine, water samples were collected and to evaluate different types of parameters. This study emphasis monthly variations of physic-chemical parameters of water. The results of present study evaluation showed that there was a significant monthly variation. The temperature was found to be maximum during summer months & minimum during winter months and range was 22-32ºC in Station-I and 24-32 ºC in Station-II. The pH of the water was found in slightly alkaline range throughout the study period and range was 7.4-8.6 in Station-I and 7.5-8.8 in Station-II. Dissolved oxygen showed marked variations and its goes to 4.0-5.4 mg/l in Station-I and 4.4-5.2 mg/l in Station-II. Total Alkalinity was 138-178mg/l in Station-I and 139-178mg/l in Station-II and Total Hardness was 129-190mg/l in Station-I and 118-199mg/l in Station-II with little bit fluctuations. However, phosphates and nitrate, were found to the slight monthly variations. The present study indicates that the fluctuations of physico-chemical parameters in the river region influence the feeding, breeding and other activities of fishes.
