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. **

Since 2004, Zoo Town Surfers has been running high quality Lochsa river rafting trips. In addition to the Lochsa, they offer Alberton Gorge, Black Foot, and Clark Fork rafting trips.

Mile 2.77 – Big Stew Creek: River Left. Big Stew creek comes in right below Morning Glory.

Mile 3.41 – House Wave: Class III. Also known as House Rock. This is a fun wave train with large waves at high water. Road mile 117.

Mile 4.30 – Grim Reaper: Class IV. Grim Reaper becomes more technical at lower water, with powerful waves at all flows. The right of center line is always open, but be mindful of laterals. Keep yur eyes peeled for the nasty hole at the bottom left of this rapid. Road mile 116.

Mile 5.00 – Shoestring: Class IV. There are large holes at low water and waves at high water that punctuate this rapid. The left of center is the usual line, with right of center being viable as well. Road mile 115.4

Mile 5.16 – Cedar Hole: At medium flows there’s a fun surf hole here.

Mile 5.25 – Jones’ Wave: Class III. Large wave train that gets larger as the river volume increases. Running outside or inside the wave train is an easy sneak at low flows, and becomes much trickier at high flows. Be ready for flips with safety in place to prepare for Horsetail rapid just downstream. Road mile 115.1

Mile 5.65 – Horsetail Falls: Class III. At low flows, the line is river left moving right. As the water comes up it changes to a right of center run. The pin rock in the center at low flows becomes a monster hole at high water. Road mile 114.8

Mile 6.21 – Lochsa Falls: Class IV. A large hole on the left turns into a crashing wave as the water rises. The wave that comes off of this is the meat of Lochsa Falls. Be prepared for a flip, as you have a 50/50 chance of making it through this river wide feature. Square up to this v-wave and paddle hard. Road mile 114.1 Learn more about Lochsa Falls.

Mile 6.42 – Picking Up the Pieces: Class III. The current pushes you to the right around some small holes, waves and rocks depending on the flows. Get your swimmers from the falls together quickly to avoid missing the beach on river left after this rapid, marked by a huge cedar on the downstream end of the beach. Road mile 113.9

Mile 8.72 – Split Creek: Class III. Right of center moving left is the line at all flows, with variations depending on ability.

Once you enter right, drive hard towards the left under the center holes to avoid car crash hole on the bottom river right of the rapid. Road mile 111.7
