Duck River Final Programmatic Environmental Impact Statement

Future water supply needs in the Upper Duck River Basin

TVA and the cooperating agencies have prepared this analysis and programmatic environmental impact statement (EIS) to document the evaluation of the need for water in the upper Duck River watershed over a 50-year planning period (up to the year 2050), to identify potential ways to meet any identified water need in part or all of this river basin, and to evaluate the environmental and socioeconomic impact of several possible ways to meet the future water needs within the basin.

A needs analysis report, issued in August 1998, indicated that the minimum flow being provided by Normandy Dam is expected to meet the water supply and water quality control needs of the Bedford County and Marshall County water service areas throughout the study period. Future demand in the Maury/southern Williamson County water service area above 40 cfs (increasingly likely to occur after the year 2015) would have to be met from other water supply sources, which would have to be able to supply as much as 22 cfs of water by 2050.

The four conceptual alternatives developed to meet this water supply need include two that could be implemented within the service area (a reservoir on Fountain Creek and a downstream intake on the Duck River), one that would affect other parts of the Duck River watershed (raising the Normandy pool level), and one that would affect an area outside of the Duck River Basin (a pipeline from Tims Ford Reservoir).

TVA is not proposing to design or construct any of the facilities proposed in the alternatives; however, as a regional water resource agency, TVA can assist in evaluating available alternatives and encourage cooperation among all communities that are dependent on common water resources.
