SR 531 - Edgecomb Creek - Fish Passage - Project Photos

Edgecomb Creek used to pass through a round culvert under State Route 531 in Arlington. The culvert was replaced with a larger box culvert to improve stream conditions for migratory fish.

The old culvert that channeled Edgecomb Creek under State Route 531 was a barrier to fish. Flows were often too fast or too shallow for fish to swim through.
