Zoological Survey of India, Northern Circle, Kaulagarh Road, Dehradun
Physico-chemical study of all three water bodies carried out throughout the year and data recorded physically for pH, temperature, alkalinity, dissolve oxygen, CO2, transparency and velocity. Physical properties generally environmentally controlled and fluctuating with the seasons but chemical properties i.e. pH, dissolve oxygen CO2 and alkalinity largely changing due to anthropogenic stresses. The pH ranges 6-9, dissolve oxygen from 7.5-13.5 mg/L, CO20.7-4.7 mg/L, alkalinity 42-110 mg/L.Variations in observed parameters also posing controlling effect on floral and faunal diversity in theses water bodies.
