WATER QUALITY STATUS OF BENISAGAR DAM CHHATARPUR DISTRICT (M.P.), INDIA

Dr. H.N. Khare and Dr. Sandeep K. Shukla

In the present study water quality status of Benisagar dam in Chhatarpur district (M.P.) India were determined during June 2012 to May 2013. Benisagar dam is situated with Longitudes and Latitudes of 24o6’ and 25o20’ on North 78o59’ to 80o26’ on East respectively with approximate182 meter above mean sea level experiencing an annual rain fall of 975-1150 m.m. Average temperature in cold 6-9 oC, summer 45-47o C, and rain 28-37oC. Banisagar dam is the most important dam of Chhatarpur district; besides being a source of water for irrigation and also the water of this dam used for artificial breading of Major Carp in the Chinese Hatchery is located here and area of the dam 380 hectare. The monthly intervals during June 2012 through May 2013 with an objective to estimate the water quality of the dam on various physico-chemical parameters Total solids, total suspended solids, total solids, turbidity and sulphate values were maximum on all the sites in rainy months, which may be due to the gradual disturbances in sedimentation of solids as well as dust particles deposited along with runoff rainwater. The alkalinity varied during different months. The values of pH, conductivity, hardness, dissolved oxygen C.O.D. and biological oxygen demand were higher during summer months. The chloride concentration was highest in the month of January and the nitrate increased in the summer months.
