No, Naini Lake is not an artificial lake. Shaped like a kidney, Naini Lake is a freshwater body. The lake is surrounded by three peaks of its three sides - Naina Peak on North West, Tiffin Top on South West, and Snow View Peaks on the north Side. The lake receives its water from the flows of surrounding hill slopes and springs. It is believed that the lake was formed tectonically, Balia Nala being the primary stream that feeds the lake.
