The Salt River Basin is located in North Central Kentucky. The basin drains about 4,150 square miles of Kentucky, and it contains approximately 9,375 miles of streams. Its Northern and Western sides meet the Ohio River, and it is surrounded by the Kentucky River Basin on its Eastern side as well as the Green and Tradewater Rivers Basin on its Southern side. The river and its tributaries run through Anderson, Boyle, Breckenridge, Bullitt, Carroll, Casey, Hardin, Henry, Larue, Marion, Meade, Mercer, Nelson, Oldham, Shelby, Spencer, Trimble and Washington counties. In these counties, there are several large cities, including Louisville, Fort Knox, and Shelbyville.
The region ranges from gently rolling to steep hills, and it also contains many wetlands, such as in Nelson County. In addition, many places in the watershed contain Karst areas, which are marked with sinkholes. See the link below for more information and a topographic map of the Salt River Basin.
The Salt River itself runs from Danville in Central Kentucky to West Point, Southwest of Louisville, Kentucky, where it meets up with the Ohio River. Along the way, the river passes through several major towns such as Shelbyville, Taylorsville, and Fort Knox, and it also creates Taylorsville Lake. Below is a map showing the Salt River and some of its major tributaries.
