Abstract:

Kashmir valley water bodies have water with alkaline character (Ph 7.1-8.9),the high values of pH being the result of photosynthetic activity from phytoplanktons. The vertical gradient of dissolved oxygen concentrations differs from one waterbody to another throughout the year. These waterbodies have highest Ionic conc. with reference to Calcium and Phosphate dominating among Anions and Cations and high conc. of Mg 3.9-8.1mg/Lwith alkalinity values of 4-376mg/L. Conductivity was 100-230µs.Due to increased abundance of phytoplanktonic activity there was an increase in Oxygen saturation and pH but there was a depletion of conductivity (due to precipitation of calcium carbonate), nutrients like NO3, N and reactive silica. The variations in time and depth of other chemical species confirm the periods of water mixing indicated by oxygen and temperature and pH values.
