The early industry in the town was logging and forestry . Three Lakes and the rest of the Northwoods supplied wood to build Chicago after the Great Chicago Fire of 1871 . During that time , most of the area 's virgin forests were cleared and it was only in the 1930s that the Civilian Conservation Corps began replanting them . As a result of these replanting efforts , logging and forestry continue to be an important industry in Three Lakes
