Three lakes (Nainital, Sattal and Naukuchiatal) in the Kumaun Himalayan region were investigated for total organic carbon and nitrogen, their atomic ratios and isotopic composition in their sediments. These geochemical proxies measured in 34-45 cm long cores indicate that organic matter preserved in the lake sediments is primarily derived from algal matter.
