The RV dump station at Lock & Dam #5 is designed for use when exiting the park. However, it is difficult to make a U-turn into the station. There is non-potable rinse water available at the station. To get to the station, you can take US 65 and State Route 46 from Redfield, then go east on State Route 46 to State Route 365. From there, go north for one block and then continue east for four miles to Tar Camp Park.
