The major lakes in Kumaun region are extremely popular tourist destinations situated in the scenic Himalayas. The lakes are also a source of drinking water, fisheries, irrigation etc to the local people. Ca, Mg, HCO3 dominate water composition and are sourced from carbonate lithology. Chloride, sulphate and nitrate are added from pollution sources. The dissolved trace elements concentrations are very low and attributed to the alkaline nature of water and phytoplanktons in the lakes.
