The grill in the shelter building needs to be fixed. Only half of the grill worked and that half was intermittent. Made it difficult to cook for a large group of people. I did report the problem to the cleaning staff, so hopefully they forwarded it on.

Visit campground every year for multi family fishing trip. It was nice having everything so green this year and we enjoyed our camping trip!

This is a nice level campground, electric included. Water is available throughout the campground so you can use your hose to fill your tank. A dump station is located just outside the park so you can dump when you leave. I also have a senior pass, so I got in for half price. A word of caution, this park fills up consistently, so plan ahead and reserve your site ahead. We took a brief automobile tour of the dam and lake beyond. I'd definitely do this park again if I were in the area.

Love the trees, play grounds for the grandkids, fishing ponds, and the Interpretive Center close by. We enjoyed swimming at the dredges in the heat of the day. Very kid friendly, as well as adult friendly campsite.

Beautiful treed park. Lots of space. We enjoyed driving across the earthen dam. We loved getting out and having dinner at the Marina. They had a favorite Montana IPA on tap. On our departure the state forecast very high winds, and we were able to reserve a site and stay. That lead us to visit Glasgow and the Museum.

Clean, well maintained campground. The sites are well laid out, never felt crowded or lacking in privacy. The wind on the other hand...
