The results from a study to determine the effects of Raccoon Mountain Pumped-Storage Plant operations on flow conditions within Nickajack Reservoir are presented. Computer simulations and field studies have shown that flow reversals occur in Nickajack Reservoir as a result of the power peaking operations of the Nickajack and Chickamauga hydroelectric plants, both situated on the Tennessee River. The primary cause of these reversals is attributable to shutdowns of the Chickamauga turbines. The focus of this study is on flow reversals near the Moccasin Bend sewage treatment plant and near the Tennessee American water treatment plant, both of which are located on the Tennessee River near Chattanooga. Results from the study show that, under normal and extreme operating conditions at Chickamauga and Nickajack Dams, operation of the Raccoon Mountain Pumped-Storage Plant has no appreciable influence on flow reversals at the two plant sites.
