Downstream Campground, operated by the Army Corps of Engineers, requires advance reservations through Recreation.gov before arrival. The campground features four loops with sites that accommodate various camping styles. Electric hookups are predominantly 30-amp, with approximately one-third offering 50-amp service. No water hookups are available at individual sites, though water spigots are distributed throughout the campground for filling tanks. The reservation system can be challenging for first-time visitors unfamiliar with the campground layout.

One visitor notes, "It's a short walk to a really wonderful interpretive center - definitely worthwhile to visit! And there's a great trail system to walk on and enjoy the views."

What campers like
Generous site spacing: Campers consistently praise the layout and spaciousness of the campground. Dave K. shares, "Sites were level and paved and had lots of space. Spacing between sites was very generous and campground was clean and well maintained."

What you should know
Advance registration required: Walk-up camping is not possible at this federal facility. One camper advises, "Need to pre-register online or by phone. The app was acting up so I called and got everything straightened out at the gate."
Limited hookups: While electric hookups are available, there are no full-service sites. Clayton B. explains, "There is no water at the sites, however, spigots are scattered throughout the camp, if one has 50 feet of hose they can probably get to a spigot to 'top off the tank'... There is a dump station on the road into the camp."
Weather considerations: Cottonwood Inn and RV Park provides an alternative glamping option near Nashua, Montana during extreme weather. The area experiences significant temperature variations with summer highs reaching mid-90s and potential for strong winds across the high prairie landscape.
