The Rolling Fork[1] is a 108-mile-long (174 km)[2] river in central Kentucky. The river flows through Marion and Hardin counties, as well as being the border between LaRue and Nelson counties. The Rolling Fork drains much of the land in these counties, and is a key part of life in this area of the Knob Region. The Rolling Fork is a part of the Salt River Basin, and the larger Ohio River Basin.
