GROUND-WATER DYE-TRACE DATA BASE AND KARST GROUND-WATER BASIN ATLAS

This cooperative program has proceeded as time permits, without special funding, for the past 3 years. Progress was made during the year as new ground-water dye-trace data were gathered, and the existing files were edited. Also, several possibilities for presenting the data have been explored, and we have decided that a series of karst ground-water basin maps will be more useful than data in a tabular format. Base maps have been obtained, and areas of responsibility tentatively assigned. Work on the first map in the series is under way. The goal is to assemble the maps into an atlas. Each map will cover a 30 by 60 minute area at a scale of 1:100,000. The catchment area will be shown for each basin with sufficient data to delineate the basin boundary. Less well-defined basins will be represented by lines connecting ground-water dye-trace input points with recovery points. In addition, some basins will be presented at a large scale in order to serve as examples of basin types or to show more detail when it is available and of special value. These maps will provide the first Statewide delineation of karst basins in Kentucky. The value of such maps and data for water supply, ground-water protection, and general economic development is significant.
