Lochsa River Rafting Guidebook

If you were to argue which river was the best day trip in Idaho, the Lochsa would probably be at the top. Pool drop Class III and IV whitewater that seemingly goes on for miles. Don’t forget the incredible roadside access that makes logistics easy. And finally, it’s also beautiful, wild, and remote. Hard to beat that anywhere else.

About this guide

This guide outlines “Section Three” from Fish Creek to Split Creek. Importantly, we are using our own mileage and not the roadside mileage that tends to be seen elsewhere. However, the roadside mileage has been noted, but is not the primary marker.

River Info

The river begins at the confluence of Colt Kill creek and Crooked Fork. Colt Kill creek gathers its name from the Lewis and Clark expedition, where they killed a horse to eat it during their expedition. The Lochsa ends its journey at its confluence with the Selway, where they become the Clearwater. The Lochsa was one of the original eight rivers to be protected under the Wild and Scenic Rivers Act of 1968.


It’s easy to get into trouble quickly on the Lochsa, especially so at high water. Pay attention, wear adequate gear (the water is cold) and stay within your skill level.


Permits are not required.

Lochsa River Madness

Lochsa River Madness is an informal but very real event that occurs annually over Memorial Weekend. It’s a celebration of boaters kicking off the rafting season. The gathering spot is highway mile marker 114, Lochsa Falls. This YouTube search will show you what you’re in for.

While there is an online gauge linked here, the gauge that everyone goes by is the one painted underneath the Lowell bridge. Between 2 – 5 feet and you’re good to go. Less than two is pretty low and above five is starting to get high. So how do you get the flow? You ask around or call the Lohsa Ranger District. Even the USGS recommends you call with this notice posted on their website:

** NOTE TO WHITEWATER RAFTERS: This stage reading is from the USGS gaging station 0.7 miles upstream from Lowell bridge. USGS stage reads between 2-3 feet higher than the stage reading on the staff gage at Lowell bridge, depending on the river stage.


For the most current stage reading from Lowell bridge, please call the Lochsa Ranger District at 208-926-4274. **

We do not have a preferred partner (yet) for the Kennebec River. If you are a commercial outfitter with an excellent reputation we would love to hear from you.

Mile 3.04 – House Wave: Class IV. Also known as House Rock. Run House up the middle of the V wave at most flows, but be sure to hit this wave straight on. Can be snuck to the right if you’re feeling conservative. This is one of the largest waves on the river at high flows. Road mile 117.

Mile 6.47 – Picking Up the Pieces: Class III. After Lochsa Falls awaits another Class III (at normal flows you have ample cleanup time). Road mile 113.9
