 At over in size, Torch Lake is the largest body of water in the system.The waterway, now clarified after traversing the immense depths of the lake, continues south through the Torch River, joins with the Rapid River, a major tributary, and empties into Lake Skegemog, a lake that is studded with large stump fields, the result of the flooding of timberlands when the lake level was raised several feet by the construction of the dam at the terminus of the system.Lake Skegemog, which is the meeting point of Grand Traverse, Kalkaska and Antrim counties, is conjoined at its western end to Elk Lake, the second-largest and final lake in the system.
