Starting in Texas County, Missouri, this spring-fed river flows 46.4 miles (74.7 km) in a general east to northeasterly direction through the heart of the geological area known as the Lower Ozark Natural Division. It is the major tributary of the Current River, ending at its confluence near Eminence, Missouri.
The first 25 miles (40 km) from the Prongs to Bay Creek is deep valley and in the springtime provides Class II water. Due to lack of access, it is the most primitive of the rivers in the region. From Alley Spring to its confluence with the Current River it is a Class I River and is floatable year round with warm water.
The Jacks Fork provides some of the most natural conditions in the region with many caves and natural springs. It is a popular recreation destination for canoeists and kayakers and is generally considered a Class I-II difficulty river.
