Barretts Diversion Dam Camping Area
Free camping at Bureau of Reclamation's Barretts Diversion Dam on the Beaverhead River, about 8 miles south of Dillon and 11 miles north of Clark Canyon Dam, just off I-15. READ THIS CAREFULLY BEFORE YOU RELY ON IT: Reclamation's brochure says of Barretts that "many people stop and use the facilities offered free to the public" and that "Day use as well as limited overnight camping is available." Those are two separate sentences -- Reclamation plainly says the facilities are free and plainly says overnight camping is allowed, but it never says in one breath that the camping itself is free, so we have listed this at lower confidence than the Clark Canyon campgrounds. The word "limited" is Reclamation's, not ours: this is a small site, not a campground loop. A large group-use shelter on the south side of the river is popular for weddings and family reunions and can be reserved through the Dillon Field Office, so it may well be booked. The site has historic interest -- Lewis and Clark wrote about the "Rattlesnake Cliffs" here, and between 1866 and 1880 this was a toll road, post office and store. Reclamation does not publish a stay limit for these campgrounds anywhere we could find -- you will see "14 nights" repeated on camping websites, but that number does not appear in any Reclamation document, so treat it as unconfirmed and ask the Dillon Field Office. Call the Dillon Field Office at (406) 683-6472 and confirm both the price and that overnight camping is still allowed before you count on this one. We have not visited it.
