Peterson Creek Fish Passage Project Tillamook, Oregon

Dedicated to conserving and restoring Tillamook County’s estuaries and watersheds, the Tillamook Estuaries Partnership is a nonprofit organization addressing the critical problems of habitat loss, decreased water quality, sedimentation, and flooding.

A Bridge Designed to Replace a Fish Barrier

In conjunction with Tillamook County Public Works and the Salmon Superhighway Partnership, the county hired Otak to lead design of a fish passage/culvert replacement project on Peterson Creek, a tributary to the Miami River on Oregon’s North Coast. A 60-foot span bridge will replace a six-foot culvert that blocks fish passage upstream, opening up several miles of potential habitat. Since this is an emergency evacuation route, the replacement structure will be constructed in stages to keep traffic and freight moving.
