A mystifying lake called the Longchao Lake located in southwest Chongqing Municipality of China, swells and shrinks three times a day. The water-body has reportedly no ditch or other lakes nearby, but it still comes up with three regular one-hour swells-and-shrinks at 8 am, 12 am and 4 pm respectively every day. Chongqing Economic Times reported that the lakes mysterious moves have instigated a latest scientific investigation of the lake organised by Chonqing exploitation Association and local hydrology and geology experts.
