There is a basic RV dump station located in front of the office. It has a potable water source, but no rinse water. However, if you pay to dump, you can use their small laundry facility, which has only two machines. We did not view the laundry facility at this time. This RV dump station is the most convenient option for those visiting Mittry Lake. To get there, you need to turn north on Laguna Dam Road (Avenue 7) from Highway 95. After approximately 2 miles, you will see the RV park on the left, just after crossing a small bridge over a canal.
