Lake Micmac is named after the Mi'kmaq people who canoed its waters for several thousand years. Remains of an overnight encampment were found on the northeast corner of the Lake just to the east of the Canal Cut which connects this lake with Lake Charles to the north. Also at the north end of the Lake is a small round island which is actually a man-made feature used to mark the route of the Canal. It is just one of a number of similar stone structures found along the waterway. The best preserved of these are found at the north end of Sullivans Pond. The other Islands which can be seen in the Lake were once part of the mainland prior to raising of the water level with the construction of the dam at the south end of Lake Banook. Lake MicMac was not connected to Lake Charles until the deep cut was made.
