First news accounts claim that on December 2nd 1892 along the shores of Lake Chelan, three men near the area now known as Stehekin were attacked by a Lake Creature that came out from the depths of the lake, grabbed one of the men and flew off with him.
Lake Chelan is 55 miles long and said to be 1,486 feet deep. There have been many claims over the years of underwater caverns in the lake, that the lake is connect to other area lakes and some even think there is an underwater connection to the Pacific.
A lake of this size has an abundant fish population that could easily sustain such a large animal. Many prominent locals have made claims to having seen the Lake Chelan Dragon throughout the lake recently.
