We did that run in August a couple years ago.
6 of us in tandem canoes, a couple and their dog in a 16 ft self bailer and one man in a super puma.
We did the trip in style with the rafts taking a couple of ice filled coolers for cold drinks and comforts of home.
Camps were just awesome except that last section was the pits. Seems like there had been a big ice dam the previous winters and all the camps were basically torn down. Other camps were awesome. Most camps had cottonwoods and other trees with plenty of shade. We made our miles early and had long cocktail time in the shade.
We were just astounded as we had winds pushing us down stream almost all of the time. There was also plenty of current and the two rafters mostly floated little time on the oars. Could not believe this.
Scenery runs from mind building rock structures reminding me of medieval castles to rolling hills. I live in Oklahoma and thought we were the wheat capital of the world. Montana tho has us beat. As we drove around we saw mile upon mile of golden wheat fields.
Look into the steam boats that used to run this river up to Ft Benton. Just awesome for me to see how they "walked" these boats up these shallow rapids. On the other hand, all the cottonwood trees were cut for miles from the river to run the boilers. The Rangers are working to replace cottonwood trees along the banks and I very much appreciate their efforts.
We had a couple awesome lightning and rain storms mostly in the evenings. Take good tents and even better tent stakes. Storms were awe inspiring with wind, rain and lightening bolts out the yeng yang. The best part is the storms were usually short in duration.
If you are a lewis and clark fan (all of us are) this float is a treat. History every where. On the way up we stopped at the Great Falls historical site. Do not miss this for the falls and the displays.
I am hoping to make this float again as it was that enjoyable.
Lots of range cattle to deal with but most of the camps are fenced off from them.
River is wide but not that deep, we could wade out to midstream at most of the camps.
You need to carry drinking water, river has all sort of fertilizer run off and not recommended you drink.
Ft Benton is a nice little town. Good little grocery store. We stayed there an extra rig day. Really nice camping at the fair grounds. Several neat places to eat. We used a local outfitter for shuttle and he was great to deal with.
There is a nice Ranger station there in Ft Benton with all the information you need plus it has some nice displays as well.
All I can say is do this trip. I sure hope to do that run again. The Breaks is a float that needs doing multiple times in my opinion. August was a good time. Warm to hot days but cool nights. There are a lot of river camps with shelters. Very nice however, several were just loaded with biting fly insects. If you use them, take plenty of bug spray.
bottom line is go and do this float. I do not know if the current and downstream wind we had is there every August but it worked just great for us.
