The source lists a $20 dump station fee but doesn't say whether registered campers pay it or whether non-campers can use it, so call ahead. Park entrance fees are listed separately. Boat ramps are currently closed for low water (park alert); that doesn't affect the dump station. The 'year-round' label means the park is open 24 hours year-round; the source gives no separate dump station hours.
