First documented by Charles E. Brown (founder of the Wisconsin Archaeological Society and museum director at the State Historical Society.) in his 1942 pamphlet on Wisconsin Sea Serpents entitled, “Sea Serpents: Wisconsin Occurrences of these Weird Water Monsters in the Four Lakes, Rock, Red Cedar, Koshkonong, Geneva, Elkhart, Michigan, and Other Lakes”, the Lake Waubesa Monster is said to have made its first “official” appearance in the early 1920’s.
