The Upper Deadwood is one of Idaho's classic backcountry runs. Flowing from the base of Deadwood Dam through a remote canyon, it offers a full day of great class IV whitewater punctuated by some Class V rapids, all set within an exceptionally scenic and isolated landscape. Many of the rapids are frequently affected by large wood, and the combination of continuous whitewater, cold water, remoteness, and ever-changing wood hazards makes this a serious run that demands experienced boaters with strong group judgment.
Historically, the Upper Deadwood ended at the Julie Creek Bridge, but the road to Julie Creek washed out decades ago and has never reopened. As a result, boaters now continue directly into the Lower Deadwood and paddle the entire river to the South Fork Payette, making for a backcountry trip of more than 20 river miles. While most parties complete the run in a long day, it also makes an excellent overnight trip with camping opportunities along the river.
The run begins below Deadwood Dam with several miles of swift Class I-II current through a forested valley. This section provides an opportunity to settle into the rhythm of the river before the gradient gradually increases and the first significant rapids appear.
A concentrated section of challenging whitewater begins shortly thereafter. Boaters should be prepared to scout major horizon lines and portage where wood hazards or changing river conditions make rapids unsafe to run. After this initial section, the river eases near the mouths of Ninemile and Scott Creeks, providing a welcome respite before entering another challenging section of technical whitewater that continues downstream toward the former Julie Creek Bridge.
Large woody debris is the defining hazard on the Deadwood. Unlike many free-flowing mountain rivers, the regulated flows below Deadwood Dam rarely produce the flushing events needed to clear fallen trees from the channel. Wood hazards can develop anywhere on th
...The old Julie Creek Campground is the traditional end point for the upper and start of the lower. Because there is no longer vehicle access to this old campground, boaters doing the upper will continue on the lower. This is a possible camp location for an overnight trip.
Because there is no longer vehicle access to Julie Creek, boaters on the Upper Deadwood will continue their runs another 9 miles on the Lower Deadwood and continue to the take-out for that run at Deadwood Campground on river left just upstream of the confluence with the South Fork Payette.

Brian Vogt --
Ran the Deadwood River in July of 2008 at a low-medium flow of 500 or so. This was a great IV level. No clean V on the run. The ranger station out of Lowman has good info on the best routes to access the putin. We headed up Canyon Creek out of Lowman, through Big Meadows/Bear Valley, then dropped down and around the reservoir. We had several portages; most for wood. There's one right off the bat in the first 1/2 mile with few eddies.
There's a IV broken ledge that kicks off the whitewater. It was clean, as was double drop. Several of the good IVs are wood choked and mandatory portages however. The V is just choked with a cats cradle of logs, and not readily apparent from the river.
The inner gorge and continuous III-IV below the one V drop was stellar. The action below the bridge was also excellent. A big log jam has blown out in the lower run, and it's obvious where. Be ready for some sketchy corners and wood for 1/2 mile below here as the old log jam has filled the next section with logs.
This is a stellar run -- one of the most scenic I've seen in a long time. Highly recommended.
