The Kentucky River Authority was first established by the Kentucky General Assembly in 1986 to take over operation of the Kentucky River Locks and Dams 5 through 14 from the United States Corps of Engineers. Following the drought of 1988, the Authority was given a mission to protect and improve the waters of the Kentucky River through environmental management of the entire watershed. It is the first effort by the Commonwealth of Kentucky to protect a great water resource through watershed management. In 1995 the Authority contracted with the Kentucky Water Resources Research Institute to perform a comprehensive water supply study for the Kentucky River Basin. The Kentucky Water Resources Institute was chosen ostensibly so as to provide a «unbiased» and scientifically based study. This study resulted in the development of two computer models KYBASIN and KYQUAL which were used to develop and evaluate five separate water supply alternatives for the Kentucky River Basin. These alternatives included: 1) conservation, 2) installation of temporary crest gates on dams 9-14; 3) construction of a large dam on the Kentucky River, 4) construction of a smaller dam on a tributary to the Kentucky River, and 5) construction of a treated-water pipeline from Louisville to Lexington.
