Isotopic investigations for lakes: A case study of Lake Nainital in Kumaun Lesser Himalaya, India

Multiple isotope tracers were used to study different aspects of Lake Nainital in Kumaun Himalaya. Mainly the isotopes were used to study the lake water balance including lake-groundwater interaction, lake — spring interconnection; lake sedimentation; and hydrodynamics. The methodology adopted and results of the investigations are briefly presented in this article as a further proof to the potential of isotope techniques in lake studies.
