Koi Hatachie was founded in 1946 by the Delta Area Council under the original name White Panther. The first Tap Out ceremony was at summer camp in July 1946 with the first meeting of the Lodge in December 1947. During Camp Tallaha's campfire programs, there was a legend of an old Choctaw Indian Chief and his constant companion, a white panther. After the Chief was killed, his white panther was said to continue to roam the land around the camp looking for his old master. The legend was so central to the camp that when the lodge was founded, the white panther was adopted as the totem and name. White Panther was used from 1946 to 1956 when the lodge changed its name to Koi Hatachie. Most Lodges had adopted Indian names and Lodge 345 wanted to conform. Koi Hatachie was thought to mean White Panther in the Choctaw language, however it was later realized to not actually have a meaning. In 1994, the last Koi Hatachie lodge chief was Thad Kelly
