Many individuals and several agencies provided information and assistance in the preparation of this atlas. The GIS students at the Federal Prison Camp, Lexington, Ky., prepared index maps and created spatial data from historical well maps. Staff members of the Kentucky Natural Resources Information System provided technical and programming assistance. Reports from the Kentucky Division of Water, the U.S. Geological Survey, the Kentucky Geological Survey, the Water Resource Development Commission, the U.S. Census Bureau, and other agencies were used. And finally, the atlas would not have been completed at this time if the Water Resource Development Commission had not promoted the project and provided both financial and technical support.
