Flood in Yamhill County, Oregon

The South Yamhill River flooded near McMinnville, where flood damage was mainly limited to parks. Damage was done to several bridges and roads throughout the county. The town of Willamina had minor flood damage, and 120 homes along with businesses and churches were damaged in Sheridan. NOTE: Damage estimates are for the entire Yamhill county.

Two very powerful storms with origins in the Tropics brought hazardous weather to the Pacific Northwest. The entire forecast area experienced heavy rainfall for an extended period of time. As an example of the extreme accumulations, over fourteen inches of rain fell at Lees Camp in the north Coast Range in a period of about 60 hours. This abnormally long period of consistently heavy rainfall led to widespread flooding, with the worst hit areas in the Coast Range and areas draining from the Coast Range to the Pacific Ocean. Five rivers in northwest Oregon surpassed major flood stages, fueling the extensive flood damage across the region.
