ISSN 2328-0328 (online) iii Acknowledgments The author thanks Benjamin L. Rohrbach and Parvathi Gaddipati of the U.S. Army Corps of Engineers for their guidance in developing this report, for their technical reviews, and for shar- ing their knowledge about the reservoir catchment areas. Personnel from many State and local agencies in Tennessee and Kentucky are acknowledged for their assistance with the compilation of data for 2010. Many employees of the U.S. Geological Survey are thanked for their contributions to this report. W. Scott Gain assisted in the development of the methods for water-use projections. Michael W. Bradley helped with the collection and compilation of the irrigation and industrial water-use data. David E. Ladd provided geographic information system support, James E. Banton helped with the figures, and Lori R. Weir assisted with the water system surveys. iv Contents Acknowledgments ........................................................................................................................................iii Abstract ..........................................................................................................................................................1 Introduction.....................................................................................................................................................1 Purpose and Scope ..............................................................................................................................2 Hydrologic Setting ................................................................................................................................2 Climate ...........................................................................................................................................2 Data Compilation and Analysis ....................................................................................................................4 Projections of Water Use ............................................................................................................................9 Estimated Use of Water in the Cumberland River Watershed in 2010 ..................................................9 Thermoelectric Power .......................................................................................................................25 Public Supply .......................................................................................................................................27 Industrial...............................................................................................................................................32 Irrigation ...............................................................................................................................................32 Public-Supply Water Projections for All Reservoir Catchment Areas to 2040 ...................................43 Martins Fork Reservoir Catchment Area ........................................................................................50 Laurel Reservoir Catchment Area ....................................................................................................51 Wolf Creek Reservoir Catchment Area ...........................................................................................52 Dale Hollow Reservoir Catchment Area .........................................................................................53 Cordell Hull Reservoir Catchment Area ..........................................................................................54 Center Hill Reservoir Catchment Area ............................................................................................55 Old Hickory Reservoir Catchment Area ..........................................................................................56 J.
