Central Oregon’s Wild and Scenic Crooked River flows through stunning basalt canyons in Central Oregon’s high desert. The region attracts outdoor lovers from around the state and the region, and provides one of the most challenging and outstanding whitewater runs in the West. The Crooked, which is a major [...]Read More
In high water this reach is often run as a continuation of the Upper Crooked, particularly by rafts that don't have a practical means of taking out at Crooked River Ranch. Known locally as the Lower Crooked.
At base flow, this reach can be run by itself as springs provide sufficient inflow through the summer for kayakers and packrafters. With some boney rapids, the one mile hike in, and an option for a two mile hike out this makes a great packraft day trip. The best gauge to refer to is Crooked River at Osborne Canyon, or COBO. This will give you an idea of how much flow you will start at China Dam with. Springs will add ~1000cfs throughout the run. Anything over 100 cfs is runnable, though over 150 is even better. Rafts would not have such a good time at summer flows. The primary issue for either rafts, or kayaks doing this section is access which is less than ideal on both ends of the run.
The dam at Opal Springs generates hydropower and is a 4.3 MW project licensed by the DeschutesValley Water District as FERC Project 5891. The project was licensed in 1982, constructed in 1985, andwill be eligible for relicensing in 2032 when the current license expires.
Logistics
To reach the put-in from Terrebone, head north on Highway 97 but before you cross the river headwest at Highway 97 mile 115.3 on Lower Bridge Road towards Crooked River Ranch. Follow Lower Bridge Rd. 2.1 miles and turn right on NW 43rd St. Continue 1.8 miles to the T junction and turn left onNW Powey Ave. Continue on this road, which becomes Chinook Dr., for 3.2 miles as it drops down tothe golf course and turn right on Clubhouse Rd. Drive in 0.4 mile heading right at the church and pastthe cabins to parking along a fence a short distance from the gorge rim. From this parking spot, youcan hike the old Hollywood Road which is the gate to the east of where you park. The road is no longeraccessible be vehicles
...In low flows, you'll want to put in somewhere below China Dam
This is the first challenging low water rapid, I call it Entry Mank because springs have not yet filled in the flow and rocks are difficult to avoid. Over 200 cfs it gets easier. Can be portaged on rocks on river left.
At low flows this is the crux rapid of the Lower Crooked. You'll enter a flat lake of water that is stopped up behind the rockfall that creates the rapid. Get out and scout on river left. The main run is full of boulders and pin rocks, and is known to catch wood regularly. Portage is fairly easy on river left across boulders. At higher flows the Wave has a tongue right of center and a large standing wave at the bottom.
Steep at first, switchbacks up river and into a gully, and then flat trail to Otter Bench Trailhead. A nice two mile walk suitable for packrafters to make the shuttle easy.

Small hydropower project requiring a portage around the dam. This can also be used as an access point for those willing to hike up the private access road to the rim (it is gated so personal vehicles can not be used to drive down to river level).
