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 river snakes along Nelson and LaRue Counties, making a u-shaped bend along the Knobs.
The Rolling Fork has a mean annual discharge of 1,828 cubic feet per second at Boston, per data collected during the period 1939–2015.
These bottoms provide excellent growing opportunities for grain farms, and surrounding pasture for cattle.
There is a healthy population of white-tailed deer, squirrels, opossums, beavers, skunks, and rabbits.
Birds such as the great blue heron and kingfisher call the river valley home.
