To use the RV dump station, there is a fee. The station provides rinse water, which is not suitable for drinking, and potable water can be found in the campground. To get to the dump station, take I-35 in Hillsboro and then go west on Hwy. 22 to Whitney. After passing Whitney, turn right before the dam and follow the park road until you reach a 4-way stop. From there, turn left to go to West Lofers or right to go to East Lofers, where you will find the gate house.
