Yes at the sites

The Sam Stowe portion of this state park campground has full hook ups but I don't recall if there is a separate dump site. If not, there are 2 RV parks roughly 5 miles east that have dump stations. Closest being Sevier River RV Park. This is a new park last year and I don't know what their fees may be.

There's a dump station in the campground. Some sites are full hook up.
