Gauge Information

River Description

The Clackamas River is well known as one of the classic whitewater runs of the Pacific Northwest with plenty of great class III intermediate whitewater. AW has been a stakeholder in the relicensing of Portland General Electric's (PGE) hydropower project on this river where we have been working with the local paddling community to advocate for river and fisheries restoration, improved public access to the river, enhanced and expanded gauge information, and a study of a playboating feature to mitigate for lost opportunities and impacts of the project.

When paddlers refer to the Upper Clackamas they mean the waters upstream of North Fork Resevoir which is part of PGE's hydropower facilties on the river. The run from Sandstone Bridge (Three Lynx) down to the Memaloose Weigh Station just above the reservoir makes a great 13.5 mile day trip although many kayakers focus on the 4.2 mile middle section from Fish Creek to Bob's Hole which serves up the best whitewater and some fine playboating. This section is also the site of the annual Bob's Hole Rodeo and races (downriver, slalom, and head-to-head) that take place at Carter Bridge.

The character of the run is mostly pool-drop class III rapids which can develop class IV hydraulics as the river rises during intense winter storms. Good consistent flows are available throughout the winter with rain and into spring as snowmelt. The river drops low in the summer but can still be enjoyed as a technical boating experience and a wonderful escape into the National Forest just an hour from downtown Portland. With Highway 224 running along the entire length of this run road scouting is easy and the road itself provides only a minimal intrusion to what is an incredible scenic journey along a forested river. Several Forest Service campgrounds, particularly in the area of Carter Bridge, make this a great weekend destination and you can build your own adventure by exploring upstream sections of the Clackamas or any of the many tributaries.

The run starts out at the Sandstone Bridge which is upstream of the Three Lynx Powerhouse. Powerhouse is a significant rapid upstream of the powerhouse which is located on river right and typically adds another shot of water to the river.

As you pass beneath the Three Lynx Bridge the river continues on with more fun class II and III and you soon reach the Narrows where the river is squeezed within a mini basalt gorge. The next significant rapid is Hole-in-the-Wall where the river slams up against the bedrock wall on river left. There have been accidents here as boaters became trapped in the recirculating current up against the wall so be sure to stay right. The road is above this rapid on river right and it's worth taking a look on the way to the put-in if you have any questions regarding the preferred line.

You will soon come to pass under another bridge and see the Fish Creek boat slide on river left. This is a good alternate put-in for a shorter run particularly at the lower range of flows. After a couple class II rapids you will come to one of the bigger drops on the run which is Carter Bridge Rapid. This rapid is upstream of the Carter Bridge and it also the site of annual races held as part of the Upper Clackamas Whitewater Festival.

After Carter Bridge the river passes through a couple more class II rapids including Slingshot before the river pools up at Big Eddy. Just below Big Eddy is Rock 'n Roll and then comes Toilet Bowl which is the last of the significant drops on the run and one of the few not easily visible from the road.

As you see the road along river right, and a line of cars parked along the shoulder, you're be at Bob's Hole. Line up on river left for you chance to surf this feature. Bob's Hole is at one of those sites along the river that is subject to change with floods and each year you can expect it to be a little different. It changed significantly in the 1996 floods and will likely change again. Many kayakers enjoy the playboating at Bob's Hole and take-out but you can continue on downstream and some even put-in here for an easier class II float of about 3 miles down to the Memaloose Weigh Station. As the river passes the weigh station it settles in behind the slackwaters of the reservoir.

Logistics

The Clackamas is reached by taking Highway 224 east out of Portland and this run is a short distance east from Estacada. The highway runs along the river providing a number of options for easy roadside access for this section of the Upper Clackamas. Although you can come up with alternatives to the options below and scramble down at any of a number of places along the river, the primary access points are designated by Highway 224 mile marker as follows:

• Mile 31.0: PGE's Promatory Park which is actually on the reservoir but has been used for river festivals in the past.
• Mile 33.5: Memaloose Weigh Station which provides good access that can also accomodate rafts and is a good access before the river settles into the slackwaters of the reservoir.
• Mile 36.7: Bob's Hole with roadside parking making this a popular park-and-play site. It's a bit of a scramble over rock rip rap to get to the river from the road.
• Mile 37.4: Big Eddy which provides a take-out above the Toilet Bowl with a good trail to the river. The site provides easy access for kayaks and you can make it work for a raft.
• Mile 38.8: Carter Bridge provides easy access to the river for rafts or kayaks on the downstream river left side of the bridge and below Carter Bridge Rapid. This is also the site of river festivals.
• Mile 39.2: Fish Creek access is reached by turning off the highway at mile 39.2 and continuing 0.3 miles to the Fish Creek river access. There is plenty of parking here and a ramp to slide rafts down to the river. There have been ongoing problems with vehicle break-ins at this site over the years.
• Mile 45.0: Three Lynx bridge downstream of the Three Lynx powerhouse is sometimes used as a river access.
• Mile 45.7: Sandstone Bridge upstream of the Three Lynx powerhouse is generally considered the start of this section and offers decent river access for all craft.
