About

An RV dump station, also known as a sanitary dump station for RVs, is a facility where RV owners can dispose of their waste. It is specifically designed to handle the disposal of sewage and wastewater from RVs. These stations are equipped with a sewer connection that allows RV owners to empty their holding tanks. RV dump stations are typically found in campgrounds, rest areas, and RV parks. They are essential for RV owners who are on the road for an extended period of time and need to empty their tanks regularly. Using an RV dump station is a responsible and hygienic way to dispose of waste while traveling.

Absolutely a great park!! Free showers if you don't mind cold water, but hot showers in the camp office. Fourth of July is an awesome time! Car show, swimming, hamburgers and hot dogs, fireworks. Great price for the sites.

Nice little campground. There is water and electric hook up which is nice. Clean restrooms and shower rooms. There is a little beach and a nice boat launch with docking - the launch and docking is a little cove away from the main water which is very nice to have as the water can because aggressive. I would recommend if looking to get away for a few days.

Loved our stay here! Nice big RV sites. Great little swimming beach and perfect sunsets over the lake. Fun 3-mile bicycle to a dam too!

Lovely quiet campground. We stayed in the group site, which had a large fire pit and lots of room for everyone. The view of the lake and nesting Ospreys with their fledglings was an awesome added bonus. The showers lost hot water pretty quickly if you didn't get one in early. The pit toliet by us was clean but didn't have much ventilation besides leaving the door open during the day. Other than that I have nothing but positives to say about this place. Well maintained. Nice staff. Dog friendly. Nice Playground and little beach. Dry firewood. Definitely will be back.

It's super nice here. All the flowers are amazing. Enjoyed seeing all the pollinators enjoying the native growth. Whoever came up with this idea, and whoever plants and maintains these flowers all deserve a raise.
