Crabtree Creek (South Santiam River tributary)

Crabtree Creek is a tributary of the South Santiam River in Linn County in the U.S. state of Oregon. It begins in the western foothills of the Cascade Range at Crabtree Mountain near Crabtree Lake. From there it flows generally west to meet the larger stream about 3 mi upstream of where the South Santiam merges with the North Santiam River to form the Santiam River.

Oregon Route 226 crosses the creek between Crabtree on the south and Scio on the north about 8 mi from the mouth. The unincorporated community of Lacomb lies south of the creek, along one of its tributaries slightly west of the Cascade foothills.

Bridges
In addition to the Route 226 bridge, the creek flows under two covered bridges. Larwood Bridge carries Fish Hatchery Road over the creek at Larwood Wayside Park, about 3 mi north of Lacomb and 16 mi by water from the creek mouth. Further downstream, Hoffman Bridge carries Hungry Hill Drive over the creek about a mile north of Crabtree and 5 mi from the mouth.

Recreation
Larwood Park lies at the confluence of Roaring River with Crabtree Creek about 16 mi by water from the creek mouth. Covering 6 acre, it has picnic tables, river views, a footbridge, a waterwheel that formerly powered a mill at the site, as well as places to fish and swim. Ripley's Believe It or Not! once listed the confluence as the only one in the world where a stream named "river" emptied into a stream named "creek". This was, however, incorrect. Fall River is a tributary of Clear Creek in Colorado.

Fishing for wild cutthroat trout in the creek is permitted on a catch-and-release basis; fishing for steelhead is not allowed. The creek is not stocked with hatchery fish.

Whitewater enthusiasts sometimes run parts of Crabtree Creek in kayaks or other craft. A 10 mi run from the North Fork Bridge to Larwood Park, is rated class 3T or 4 (intermediate or advanced) on the International Scale of River Difficulty. The 15.5 mi run below that is less difficult. Hazards include rocks, logs, overhanging limbs, and a dangerous barbed-wire fence across most of the river a few miles downstream of the Route 226 bridge.
