NPS says the RV dump station (with potable water) is only for people with receipts showing they're camping in Amistad National Recreation Area campgrounds. It's along the road to the Diablo East boat ramp. Current alerts (2026-11-07) close parts of Diablo East (marina cove, scuba cove, walkway) and some boat ramps for low water, not the dump station. Winter status of the dump station isn't stated.
