Human being requires more water as compared to any other terrestrial organism. Hence the great human civilizations have developed near the fresh water bodies. Therefore the aspect of water use, as every one have become aware of water as a limited natural resources as precious if not yet as scared as gold or oil.

The Pond is selected in the outskirts of village Newara, which is 22 km. away from Bilaspur towards Bilaspur-Kota road.

The present study reveals the assessment of pond water in Newara village with respect to some physico-chemical parameters.

The study was carried out for the month of January to December during the year 2006. The water samples ware collected from surface near the margins of the pond between 8.30 am. to 10.30 am. The analysis of physico-chemical parameters were made by following APHA-AWWA-WPCF 1985.

The physico-chemical parameters of pond water are given in Table 1. The pond water temperature was observed minimum 18.6°C in the month of February and maximum 31°C in the month of Jun. Ph had very little variation in the values throughout the year however the value ranged from 7.21 to 8.87, Chloride content had showed a values change in the all months, the values ranged from 117.74 to 469.9 mg./^-1. The maximum value of 905.76 mg./^-1, total Hardness was obtained in the month of February, while lowest value of 87.67 mg/^-1in September Dissolve oxygen was ranged from 1.06 to 8.61 mg/^-1. The minimum value was recorded in the month of the May and Jun maximum in December it was resulted due to greater consumption of oxygen by organism during the summer months, May and Jun as compared to December. BOD values were ranged from 9.18 mg./^-1to 36.6mg./^-1. The minimum value was record in the month of Jun and maximum in January. The higher in the month of Jun infers the greater rate of biological oxidation in prevailing higher temperature of the pond water. Minimum values of COD was noted in the month of August 240 mg./^-1and maximum value of the month of April. The higher value of COD during the summer was due to higher rate of evaporation.

The analysis of physico-chemical parameter had indicated the wider human activity and in flux of domestic wastes in ponds which Caused the eutrophication ponda of the century. So the pond has showed enormous growth of phytoplankton throughout the study period.
