Corinth Water Supply
Tishomingo County, Mississippi
On November 1, 2006, TVA issued a Supplemental Environmental Assessment and Finding of No Significant Impact for approval of the Corinth Water Supply project under Section 26a of the TVA Act. The Supplemental EA and an EA prepared by the U.S. Army Corps of Engineers assess the environmental impacts of a water intake proposed by the Corinth Gas and Water Department
The Corinth Gas and Water Department proposes to construct a water intake on the Tennessee-Tombigbee Waterway (TTW) near Doskie, Mississippi. Up to 16.5 million gallons per day of water would be withdrawn. The water intake would be located in the Tennessee River Watershed along the former channel of Yellow Creek, and therefore would constitute an obstruction requiring approval under Section 26a of the TVA Act. Water levels in the divide section of the TTW are at the same level as TVA’s Pickwick Reservoir. This water derives from the Tennessee River system rather than from the Tombigbee/Mobile Bay watershed and removals for use by the city of Corinth would constitute an inter-basin transfer into the Hatchie River watershed. The U.S. Army Corps of Engineers issued an EA for its approval of the water intake and 19-mile transmission pipeline on July 6, 2006.
The TVA Supplemental EA analyzes the potential effects of the withdrawal on the operation of Pickwick Reservoir and the Tennessee River system. This analysis determined that the proposed withdrawal rate would result in no change in minimum flow and insignificant changes to reservoir elevations. The diversion would reduce hydropower generation by an insignificant fraction of TVA system generation.
