Washington’s legendary volcanoes – Mount Rainier, Mount St. Helens, and Mount Adams – are the source of wild, free-flowing rivers and streams that cascade over big drops and through deep basalt canyons on their way to the Columbia River. Rivers like the Clear Fork of the Cowlitz, Cispus, Green, [...]Read More

Fun rapids, scenic canyons, and an easy shuttle make this a great run, particularly after a good rain event. The run starts gently with wide, shallow Class II water. The first defined drop below Road 7300 is a nice Class III boulder garden with some decent gradient. From there, the run gradually steepens and the canyon tightens. The action builds to consistent Class III with a nice variety of small ledges and boulder gardens. Waterfalls and cascading side streams add flow throughout the run. Many folks get familiar with the river by running from Road 7300 to Road 6600 a few times before attempting the harder rapids in the lower canyon.
After passing under the bridge at Jacks Creek, you are about a mile upstream of Double Drop. There is one steep ledge above DD, and then immediately above it there's a short, quiet pool. Double Drop can be scouted on the left, though the view is not ideal. There is also a trail down to it on river right, but finding that might require local guidance. At low flows the first drop can be arduously portaged on the left. Double Drop begins with a straightforward lead-in as the river narrows into a tight channel and a powerful ledge. Below the ledge, a midstream boulder forces a choice: left is the cleanest line, while right will take you through some big holes. A long recovery pool sits below the drop.
Below Double Drop, Class III water continues before easing back to Class II as you approach the takeout.
Access Logistics: The takeout is located at the gate below Jack's Creek. Follow Bennett’s directions up Kalama River Road. If you have a permit, you can continue upriver to a variety of put-in options depending on the length of run you want. The gate provides access to the Weyerhaeuser Mt. St. Helens Tree Farm and while it was opened during hunting season in the past it is now only available through a limited-entry pe
...A 38' waterfall at the headwaters of the Kalama River.
Access point at the 7200 Bridge, a short distance downstream of Kalama Falls.
The river leaves the road and becomes more remote as you pass through the boulder garden at Wolf Creek.
Access point at the Weyerhaeuser 6600 Bridge that crosses the river at the Jacks Creek confluence. This is a potential exit point for those seeking to avoid Double Drop located approximately 1.5 miles downstream of this bridge.
A take-out is available on upstream river right of the bridge. This is the take-out described in Bennett's guidebook. It is just upstream of Gobar Creek and the Weyerhaeuser gate.

I was one of the lucky few to get invited on a spring Upper Kalama Kampout by this year's permitholders. The river is a delightful with fantastic water quality, good clean rapids, and pretty scenery with cliffs and eagles. The bigleaf maples were just leafing out, and the dogwoods were in full bloom.
We ran it two days in a row at 440 and 420 cfs on the gauge below. I would call this low, but not very low, because there are still multiple clean lines through every drop. You could certainly go lower--not sure what the minimum is. Before the gate was closed we used to come in here without a gauge and run it high--it has a lot less playful features when high. This time I brought my half slice and did not regret it; there were lots of fun surfing waves and moves to make in the rapids.
The URL for the gauge changed last year, and currently it's https://www.licor.cloud/dashboards/public/4c98589d-ef81-4d4f-9573-bc6062d4aae0/true?filters={%22davra-timeselector%22:{%22type%22:%22relative%22,%22unit%22:%22weeks%22,%22value%22:1,%22live%22:false}}.
Double drop is, IMO, more challenging at low water than high. Perhaps this is because folks told me to run right: I found the right side of the ledge terrifying due to perceived pin risk (between R wall and whatever rock is causing the water pile in the middle). On day 2 I ran left and it looks to me like left or center can lead to a good boof and controlled exit. Some folks went straight over the woop-dee-woo (pile of water) in the middle and of those, a high proportion got awesome backenders and more excitement in the hole.
