KENTUCKY DOCUMENTATION AND NOTES
Last edited: Friday August 5, 2005

      By statute, the Commonwealth of Kentucky has legal authority to regulate withdrawals from public waters.  The Kentucky Natural Resources and Environmental Protection Cabinet, Division of Water (KDOW), Water Quantity Section administers the water-withdrawal-permit program. Industrial and public suppliers that withdraw over 0.01 Mgal/d are required to have a permit. Irrigation withdrawals are exempt from the permit requirement.  Site-specific data were provided by the KDOW for 267 public water-supply facilities and 120 industrial facilities to the USGS. These data were aggregated at the county level. 
      
      In 2000 total water ground-water withdrawals in Kentucky was approximately 189 Mgal/d.  Ground-water withdrawals in the categories of public supply, self-supplied industrial, and irrigation are 88 per cent of total ground-water withdrawals (167 Mgal/d).  Ground-water withdrawals assigned to alluvial aquifers totaled 123 Mgal/d and ground-water withdrawals assigned to other totaled 1.24 Mgal/d and were attributed to irrigation withdrawals.  Irrigation estimates for crop and non-crop (golf courses) were developed at the state level. An estimate of ground-water withdrawals was computed as 4 percent of the total withdrawals. The estimated 4 percent ground-water withdrawal allocation is not spatially referenced and the aquifer systems in Kentucky have not been conclusively defined.   Therefore the entire irrigation estimate of 1.24 Mgal/d ground-water withdrawals for crop and non-crop irrigation was allocated to the other aquifer category.
      
      The northern border of Kentucky is defined by the Ohio River.  An alluvial aquifer along the Ohio River is the most intensively used aquifer in Kentucky. The towns of Owensboro, Hawesville, Brandenburg, Louisville, and Carrollton are located along the river and depend upon large surface supplies from the river and on ground-water supplies from shallow wells screened in the alluvium. A dependable supply is ensured by constructing wells near the river to induce infiltration.  In Kentucky the only place that an alluvial aquifer has been mapped is in a narrow band along the Ohio River. This band corresponds to the area shown as a stream-valley aquifer on figure 4, chapter K, of the Ground Water Atlas. 
      
       In the 2000 compilation, all the ground-water withdrawals (123 Mgal/d) classified as originating in the category alluvial aquifers are assumed to represent potential Ohio stream-valley aquifer pumpage.  The southern extent of Quaternary continental glaciation extends into Kentucky in places along the Ohio River.  The counties of Boone, Carroll, Gallatin, Kenton, Oldham, and Trimble are each partially north of the line of glaciation. As withdrawals north and south of the line of glaciation could not be differentiated using the county data, for this analysis, the ground-water pumpage from these counties (21.6 Mgal/d) was not used. The remaining 102 Mgal/d alluvial aquifer withdrawals are attributed to the Ohio stream-valley aquifer. These withdrawals are split between self-supplied industrial withdrawals (60.9 Mgal/d) and public supply withdrawals (40.8 Mgal/d).
      
      
      
      
      Note:
      The 1987 National Water Summary mapped withdrawals from the alluvial aquifer to an area along the Ohio River Main Stem. It was assumed that the Ohio River has continued to contribute all withdrawals attributed to the unit, alluvial aquifer.  Site specific data for Kentucky were not used for the analysis. The counties of: Boone, Carroll, Gallatin, Kenton, Oldham, and Trimble are at least in part north of the line of glaciation. County data provide total ground-water withdrawals but do not indicate aquifer units. As a conservative estimate of stream-valley aquifer water use, all ground-water pumpage from these six counties was assumed to originate from wells screened in either glacial deposits or consolidated rock aquifer units rather than from stream-valley alluvium. Thus total pumpage for the public supply and industry category from these counties was subtracted from the total Kentucky alluvial aquifer withdrawals to obtain the Ohio stream-valley aquifer withdrawal values.
