Not much to do without a power boat. Kids fishing ponds are algae choked and probably bare of fish. Power house and museum closed except weekends. RV dump water barely flows, and one faucet not working.

We love Downstream Campground. It is our favorite campground from all we have tried. The sites are spaced apart by at least 15 feet giving you privacy from your neighbors. There are lots of large trees providing shade. The bathrooms and bathhouse are very clean. Electricity hookups are available in many sites. Reservations are encouraged as the campground has been full all four years that we have been there. The camp hosts are nice people and we look forward to seeing them each summer. There is a walking path around the whole park that takes you by the water and the campground is close to the Ft. Peck power plant which has a wonderful visitors center that gives the history of the area and building of the dam which was quite an accomplishment in the 30’s. The town of Ft. Peck is up the hill and offers a summer theater with musicals and plays on the weekends. The reservoir is huge and beautiful and contains many varieties of fish including walleye, northern pike, salmon, and bass. We also fish in the dredge cuts when the water on the lake is too choppy. There is a free dump station as you leave the campground and there are a couple of spots to use to fill your water tanks on the property if you are not wanting the extra weight of traveling with your tanks full.

This was a wonderful campsite to stay for the night. I had a tent and the site host moved me to a more shaded spot at the temps were in the low 100s and the evening was only going to be in the low 70s. This was a big help. The nearby showers and restrooms were clean and easy to access. I will definitely consider reserving other state park campgrounds. Having a reserved space and quiet hours which are complied with are a welcome benefit. Thanks for making this so easy to schedule and reserve.

Camp sites were close together. At some sites more than one family was occupying the site and had two to four vehicles some with boats parked crowding our site. The showers and bathrooms are separate The new showers had little water pressure and it took forever to rinse the soap out of your hair. No soap in the bathrooms with covid-19 warnings posted?
