Willamina Creek

Willamina Creek is a tributary, about 20 mi long, of the South Yamhill River in the U.S. state of Oregon. Beginning in the Northern Oregon Coast Range in Yamhill County, it briefly enters and exits a small part of eastern Tillamook County, then flows generally south to meet the larger stream at Willamina, near the border with Polk County.

Course
From its source northeast of Stony Mountain, the creek flows south, passing under Willamina Creek Road about 18 mi above the mouth. The road follows the creek from here to Willamina. Turning west, the creek passes over Willamina Falls between river miles (RM) 17 and 16 (river kilometers 27 and 26) and enters Tillamook County. Veering south again, it flows through segments of Tillamook State Forest before re-entering Yamhill County about 13 mi from the mouth. It passes Buck Hollow Cemetery and then flows through Blackwell Park at about RM 5 (RK 8). Turning east at Willamina, it enters the South Yamhill River about 43 mi from the larger stream's mouth. Named tributaries of Willamina Creek from source to mouth are Cedar, East, Coast, and Tindle creeks.

Waterfall
The Northwest Waterfall Survey describes Willamina Falls as a "veiling plunge" that is 40 ft high and 20 ft wide. It estimates the average discharge at this point at 150 cuft/s with the highest flows in winter and spring. The waterfall is on private land.

Recreation
Blackwell Park is a county recreational area along Willamina Road and the creek about 4.5 mi north of Willamina. The 6 acre site offers stream views, picnic sites, fishing, barbecue pits, and a public toilet. Two families named Blackwell donated the land for the park in 1957.

Fishing in Oregon calls the creek "a good little trout stream". The creek offers catch-and-release fishing for wild cutthroat up to 11 in long.
