The Current River and its tributary the Jacks Fork are the heart of the Ozark National Scenic Riverways and in fact the very reason for the park's existance is to protect these two streams. Mostly spring-fed and running through some of the most beautiful Ozark scenery, they attract some 1.5 million visitors each year. Most come to float, fish, swim and otherwise partake of the rivers' charms.
