We haven't personally camped here. Everything below is pulled from public land data, USGS maps and OpenStreetMap — a real place on U.S. Bureau of Reclamation land, but not field-checked by us. Confirm road conditions, current access, stay limits and fire restrictions before you go.

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.

Confidence
Likely — The record is good enough to put a pin on, but thin in places. Treat the details as a starting point, not gospel.
How it was placed
Provenance: USBR facilities record for Clark Canyon Reservoir, Fees block verbatim: "Area Entrance no / Campgrounds no / Picnic Areas no / Boat Launch Facilities no / Parking no / Other yes" with "Campgrounds 9 / Campsites 96"; Cooperator (managing entity) = "Bureau of Reclamation, 1200 Highway 41 East, Dillon MT 59725" (usbr.gov/gp/recreation/ccrrec.html, page states "Last Updated: 9/29/17"). Reclamation's Clark Canyon brochure covers Barretts Diversion Dam on the same project and states verbatim: "Even today many people stop and use the facilities offered free to the public. Day use as well as limited overnight camping is available." The Reclamation MTAO project page (usbr.gov/gp/mtao/clarkcanyon/, "Last Updated: 3/16/23") confirms recreation on Clark Canyon Reservoir AND Barretts Diversion Dam is managed by the Bureau of Reclamation. Rated 'med' NOT 'high' because the free-ness and the camping are asserted in two separate sentences and no fee table entry is specific to Barretts. No stay limit is published by Reclamation in the facilities record, the brochure or the map, and recreation.gov's Clark Canyon gateway contains none of the words free/fee/night/stay/limit. The widely repeated "free for up to a 14 night stay" is aggregator-only and is NOT asserted here. Coordinate from OpenStreetMap node/12113075963 ("Barretts Station Campground", tourism=camp_site), which lies 390 ft from OSM node/357923686 "Barretts Dam"; that this OSM object is Reclamation's site is INFERRED FROM POSITION and is not stated by either source -- flagged in field_note.

What we don’t know

A land record can put you within a few metres of a spot. It cannot tell you any of this — so check it yourself, and treat anything below as the open question it is.
