Premise: Nickajack Lake is the reservoir created by Nickajack Dam as part of the Tennessee Valley Authority. The lake stretches from Nickajack Dam to Chickamauga Dam, passing through the city of Chattanooga. The stretch of the Tennessee River commonly referred to as the "Grand Canyon of Tennessee" also is part of Nickajack Lake.
Hypothesis: Nickajack Lake does not pass through the city of Chattanooga.
