To evaluate the water composition of the lake. Total 20 samples of water were collected for analysis of different salts from the lake and 10 samples were once again collected after laps of two years from the previous selected points to show the difference in result. We also monitor the two years precipitation, Sun shine hour, average temperature and bacterial composition to support result. From this investigating we come to know following results.
i. Coloiform bacteria in all 20 samples were greater than 240 /100 ml.
ii. The concentration of Alkalinity 2.18 m.mol/l Sulfate 37.5, Potassium1.56 and Calcium 48.1 of lake water increase ppm within two years.
iii. While the concentration of Chloride 37.2, sodium 7.5, Magnesium 33.6, Bicarbonate 81.4 ppm are decreases with the passage of time.
iv. The mean Precipitation rate in 2010, 2011and 2012 is 191.4, 409.2 and 275.4 mm respectively.
v. The mean average temperature is -5° C minimum during winter season and 36° C maximum during summer.
vi. The mean sun shine rate also fluctuate with months of years during winter the sun shine rate become low 6hours per day but during summer the sunshine rate at its peak at 11hours per day. The lake water is unfit for drinking purpose due to higher concentration of coliform.
